The tool loop maintains its own message list internally and never re-reads from the provider. + +2. **`ChatMiddleware` modifies copies**: `ChatMiddleware` receives a **copy** of the message list each iteration. Clearing/replacing `context.messages` in middleware only affects that single LLM call — the tool loop's internal message list keeps growing with each tool result. + +3. **`FunctionMiddleware` wraps tool calls, not LLM calls**: `FunctionMiddleware` runs around individual tool executions, not around the LLM call that triggers them.

Any middleware-based approach only affects individual LLM calls but the underlying list keeps growing. + +### Message-list correctness constraint: Atomic group preservation + +A critical correctness constraint for any compaction strategy: **tool calls and their results must be kept together**. LLM APIs (OpenAI, Azure, etc.) require that an assistant message containing `tool_calls` is always followed by corresponding `tool` result messages. A compaction strategy that removes one without the other will cause API errors. This is extended for reasoning models, at least in the OpenAI Responses API with a Reasoning content, without it you also get failed calls. + +Strategies must treat `[assistant message with tool_calls] + [tool result messages]` as atomic groups — either keep the entire group or remove it entirely.

Instead, compaction should only trigger when a threshold is exceeded. There are several approaches to consider: + +1. **Message count threshold**: Trigger when the message list exceeds N messages. Simple to implement and predictable, but message count is a poor proxy for token usage — a single tool result can contain thousands of tokens while counting as one message. + +2. **Character/token count threshold**: Trigger when the estimated token count exceeds a budget. More accurate but requires a token counting mechanism (exact tokenization is model-specific and expensive; character-based heuristics like `len(text) / 4` are fast but approximate). + +3. **Iteration-based**: Trigger every N tool loop iterations (e.g., every 10th iteration). Predictable cadence but doesn't account for actual context growth — 10 iterations with small results may not need compaction while 3 iterations with large results might. + +4. **Strategy-internal**: Let the `CompactionStrategy.compact()` method decide internally — it receives the full message list and can return it unchanged if no compaction is needed. This is the simplest integration point (always call `compact()`, let the strategy no-op when appropriate) but has the overhead of calling into the strategy every iteration. + +The recommended approach is **strategy-internal with a lightweight guard**: the `compact()` method is called after each tool result, but strategy implementations should include a fast short-circuit check (e.g., `if len(messages) < self.threshold: return False`) to minimize overhead when compaction is not needed. This keeps the tool loop simple (always call `compact()`) while letting each strategy define its own trigger logic. + +The following example illustrates this for Variant A (in-place flat list).

At that moment in the run, the message list is passed to the strategy's `compact()` method, which returns whether compaction occurred (and depending on the variant, either mutates in place or returns a new list). +1. The caller continues with the (potentially reduced) list for the next steps (sending to the model, saving to storage, or continuing the tool loop with the reduced context) +1. We need to decide how to handle a failed compaction (e.g., the strategy raises an exception) — likely we should have a fallback to continue without compaction rather than failing the entire agent run. + +#### Compaction on existing storage + +ADR-0016's `HistoryProvider.save_messages()` is an **append** operation — `after_run` collects the new messages from the current invocation and appends them to storage. There is no built-in way to **replace** the full stored history with a compacted version. + +For compaction on existing storage (and pre-write compaction that rewrites history), we need a way to overwrite rather than append.

For measuring **consistency** (does the same query produce reliable results?), use `num_repetitions` to run each query N times independently: + +**Python:** + +```python +evals = FoundryEvals( + project_client=client, + model_deployment="gpt-4o", + evaluators=[FoundryEvals.RELEVANCE, FoundryEvals.COHERENCE], +) + +results = await evaluate_agent( + agent=my_agent, + queries=[ + "What's the weather in Seattle?", + "Plan a weekend trip to Portland", + "What restaurants are near Pike Place?", + ], + evaluators=evals, +) +for r in results: + r.assert_passed() +``` + +**C#:** + +```csharp +var evals = new FoundryEvals(chatConfiguration, FoundryEvals.Relevance, FoundryEvals.Coherence); + +AgentEvaluationResults results = await agent.EvaluateAsync( + new[] { + "What's the weather in Seattle?", + "Plan a weekend trip to Portland", + "What restaurants are near Pike Place?", + }, + evals); + +results.AssertAllPassed(); +``` + +`evaluate_agent` returns one `EvalResults` per evaluator. Each result contains per-item scores with the evaluated response for auditing: + +``` +# results[0] (FoundryEvals) +EvalResults(status="completed", passed=3, failed=0, total=3) + items[0]: EvalItemResult( + query="What's the weather in Seattle?", + response="It's currently 72°F and sunny in Seattle.", + scores={"relevance": 5, "coherence": 5}) + items[1]: EvalItemResult( + query="Plan a weekend trip to Portland", + response="Here's a 2-day Portland itinerary...", + scores={"relevance": 4, "coherence": 5}) + items[2]: EvalItemResult( + query="What restaurants are near Pike Place?", + response="Top restaurants near Pike Place Market: ...", + scores={"relevance": 5, "coherence": 4}) +``` + +#### Measure consistency with repetitions + +Run each query multiple times to detect non-deterministic behavior: + +**Python:** + +```python +results = await evaluate_agent( + agent=my_agent, + queries=["What's the weather in Seattle?"], + evaluators=evals, + num_repetitions=3, # each query runs 3 times independently +) +# results contain 3 items (1 query × 3 repetitions) +``` + +**C#:** + +```csharp +AgentEvaluationResults results = await agent.EvaluateAsync( + new[] { "What's the weather in Seattle?" }, + evals, + numRepetitions: 3); // each query runs 3 times independently +// results contain 3 items (1 query × 3 repetitions) +``` + +#### Evaluate a response you already have + +When you already have agent responses, pass them directly to skip re-running the agent. Each query is paired with its corresponding response: + +**Python:** + +```python +queries = ["What's the weather?", "What's the capital of France?"] +responses = [await agent.run([Message("user", [q])]) for q in queries] + +results = await evaluate_agent( + responses=responses, + evaluators=evals, +) +``` + +**C#:** + +```csharp +var queries = new[] { "What's the weather?" }; +var responses = new List(); +foreach (var q in queries) + responses.Add(await agent.RunAsync(new[] { new ChatMessage(ChatRole.User, q) })); + +AgentEvaluationResults results = await agent.EvaluateAsync( + responses: responses, + evals); +``` + +Each `AgentResponse` already contains the conversation (query + response), so the evaluator extracts query/response from the conversation. When you pass `responses` without `queries`, the conversation is the source of truth. + +#### Evaluate with conversation split strategies + +By default, evaluators see only the last turn (final user message → final assistant response). For multi-turn conversations, you can control how the conversation is factored for evaluation: + +**Python:** + +```python +results = await evaluate_agent( + agent=agent, + queries=["Plan a 3-day trip to Paris"], + evaluators=evals, + conversation_split=ConversationSplit.FULL, # evaluate entire trajectory +) + +# Or per-turn: each user→assistant exchange scored independently +results = await evaluate_agent( + agent=agent, + queries=["Plan a 3-day trip to Paris"], + evaluators=evals, + conversation_split=ConversationSplit.PER_TURN, +) +``` + +**C#:** + +```csharp +// Full conversation as context +AgentEvaluationResults results = await agent.EvaluateAsync( + new[] { "Plan a 3-day trip to Paris" }, + evals, + splitter: ConversationSplitters.Full); + +// Per-turn splitting +var items = EvalItem.PerTurnItems(conversation); // one EvalItem per user turn +var results = await evals.EvaluateAsync(items); +``` + +With `PER_TURN`, a 3-turn conversation produces 3 scored items: + +``` +EvalResults(status="completed", passed=3, failed=0, total=3) + items[0]: query="Plan a 3-day trip to Paris" scores={"relevance": 5} + items[1]: query="What about restaurants?" scores={"relevance": 4} + items[2]: query="Make it budget-friendly" scores={"relevance": 5} +``` + +#### Evaluate a multi-agent workflow + +**Python:** + +```python +result = await workflow.run("Plan a trip to Paris") +eval_results = await evaluate_workflow( + workflow=workflow, + workflow_result=result, + evaluators=evals, +) + +for r in eval_results: + print(f" overall: {r.passed}/{r.total}") + for name, sub in r.sub_results.items(): + print(f" {name}: {sub.passed}/{sub.total}") +``` + +**C#:** + +```csharp +WorkflowRunResult result = await workflow.RunAsync("Plan a trip to Paris"); + +IReadOnlyList evalResults = await result.EvaluateAsync(evals); + +foreach (var r in evalResults) +{ + Console.WriteLine($" overall: {r.Passed}/{r.Total}"); + foreach (var (name, sub) in r.SubResults) + Console.WriteLine($" {name}: {sub.Passed}/{sub.Total}"); +} +``` + +Workflows return one result per evaluator, with sub-results per agent in the workflow: + +``` +EvalResults(status="completed", passed=2, failed=0, total=2) + sub_results: + "planner": EvalResults(passed=1, total=1) + "researcher": EvalResults(passed=1, total=1) +``` + +#### Mix multiple providers + +**Python:** + +```python +@evaluator +def is_helpful(response: str) -> bool: + return len(response.split()) > 10 + +foundry = FoundryEvals( + project_client=client, + model_deployment="gpt-4o", + evaluators=[FoundryEvals.RELEVANCE, FoundryEvals.COHERENCE], +) + +results = await evaluate_agent( + agent=agent, + queries=queries, + evaluators=[is_helpful, keyword_check("weather"), foundry], +) +``` + +**C#:** + +```csharp +IReadOnlyList results = await agent.EvaluateAsync( + queries, + evaluators: new IAgentEvaluator[] + { + new LocalEvaluator( + EvalChecks.KeywordCheck("weather"), + FunctionEvaluator.Create("is_helpful", (string r) => r.Split(' ').Length > 10)), + new FoundryEvals(chatConfiguration, FoundryEvals.Relevance, FoundryEvals.Coherence), + }); +``` + +Multiple evaluators return one result each — `results[0]` is the local evaluator, `results[1]` is Foundry. + +#### Custom function evaluators + +**Python:** + +```python +@evaluator +def mentions_city(response: str, expected_output: str) -> bool: + return expected_output.lower() in response.lower() + +@evaluator +def used_tools(conversation: list, tools: list) -> float: + # ... scoring logic + return score + +local = LocalEvaluator(mentions_city, used_tools) +``` + +`@evaluator` uses **parameter name injection** — the function's parameter names determine what data it receives from the `EvalItem`.

Per-agent breakdown in `sub_results`. Also accepts `num_repetitions=` | + +### Core: Conversation Split Strategies + +Multi-turn conversations must be split into query (input) and response (output) halves for evaluation. How you split determines *what you're evaluating*: + +**Last-turn split** — split at the last user message. Everything up to and including it is the query context; the agent's subsequent actions are the response: + +``` +conversation: user1 → assistant1 → user2 → assistant2(tool) → tool_result → assistant3 +query_messages: [user1, assistant1, user2] +response_messages: [assistant2(tool), tool_result, assistant3] +``` + +This evaluates: "Given all the context so far, did the agent answer the latest question well?" Best for response quality at a specific point in the conversation. + +**Full-conversation split** — the first user message is the query; everything after is the response: + +``` +query_messages: [user1] +response_messages: [assistant1, user2, assistant2(tool), tool_result, assistant3] +``` + +This evaluates: "Given the original request, did the entire conversation trajectory serve the user?" Best for task completion and overall conversation quality. + +**Per-turn split** — produces N eval items from an N-turn conversation. Each turn is evaluated with its cumulative context: + +``` +item 1: query = [user1], response = [assistant1] +item 2: query = [user1, assistant1, user2], response = [assistant2(tool), tool_result, assistant3] +``` + +This evaluates each response independently. Best for fine-grained analysis and pinpointing where a conversation goes wrong. + +These factorings produce different scores for the same conversation. The framework ships all three as built-in strategies, defaulting to last-turn. Developers can also provide a custom splitter — a function (Python) or `IConversationSplitter` implementation (.NET) — and override the strategy at the call site or per evaluator. + +### Azure AI: FoundryEvals + +`Evaluator` implementation backed by Azure AI Foundry: + +```python +class FoundryEvals: + def __init__(self, *, project_client=None, openai_client=None, + model_deployment: str, evaluators=None, ...) + async def evaluate(self, items, *, eval_name) -> EvalResults +``` + +**Smart auto-detection in `evaluate()`:** +- Default evaluators: relevance, coherence, task_adherence +- Auto-adds `tool_call_accuracy` when items have tools/`tool_definitions` +- Filters out tool evaluators for items without tools + +### Azure AI: FoundryEvals Constants + +```python +from agent_framework_azure_ai import FoundryEvals + +evaluators = [FoundryEvals.RELEVANCE, FoundryEvals.TOOL_CALL_ACCURACY] +``` + +Categories: Agent behavior, Tool usage, Quality, Safety. + +### Azure AI: Foundry-Specific Functions + +| Function | What it does | +|---|---| +| `evaluate_traces()` | Evaluate from stored response IDs or OTel traces | +| `evaluate_foundry_target()` | Evaluate a Foundry-registered agent or deployment | + +### Core: LocalEvaluator and Function Evaluators + +`LocalEvaluator` implements the `Evaluator` protocol for fast, API-free evaluation.

Evaluators that accept the full `EvalItem` or `conversation` parameter can access this content today. However, the convenience shortcuts — `query`/`response` string projections and the `FunctionEvaluator` string overloads — are text-only. Multi-modal-aware evaluators should use the full-item path (`Func` in .NET, `conversation: list` parameter in Python). + +## .NET Implementation Design + +### Key Difference: MEAI Ecosystem + +Unlike Python, the .NET ecosystem already has `Microsoft.Extensions.AI.Evaluation` (v10.3.0) providing: + +- `IEvaluator` — per-item evaluation of `(messages, chatResponse) → EvaluationResult` +- `CompositeEvaluator` — combines multiple evaluators +- Quality evaluators — `RelevanceEvaluator`, `CoherenceEvaluator`, `GroundednessEvaluator` +- Safety evaluators — `ContentHarmEvaluator`, `ProtectedMaterialEvaluator` +- Metric types — `NumericMetric`, `BooleanMetric`, `StringMetric` + +The .NET integration uses MEAI's `IEvaluator` directly — no new evaluator interface.

Key differences from the legacy VSTest runner: + +- **`dotnet test` requires `--project`** to specify a test project directly (positional arguments are no longer supported). +- **Test output** uses the MTP format (e.g., `[✓112/x0/↓0]` progress and `Test run summary: Passed!`). +- **TRX reports** use `--report-xunit-trx` instead of `--logger trx`. +- **Code coverage** uses `Microsoft.Testing.Extensions.CodeCoverage` with `--coverage --coverage-output-format cobertura`. +- **Running a test project directly** is supported via `dotnet run --project `. This bypasses the `dotnet test` infrastructure and runs the test executable directly with the MTP command line. + +- **Running tests across the solution** with a filter may cause some projects to match zero tests, which MTP treats as a failure (exit code 8). Use `--ignore-exit-code 8` to suppress this: + +```bash +# Run all unit tests across the solution, ignoring projects with no matching tests +dotnet test --solution ./agent-framework-dotnet.slnx --no-build -f net10.0 --ignore-exit-code 8 +``` + +- **Running tests with `--solution` for a specific TFM** requires all projects in the solution to support that TFM. Not all projects target every framework (e.g., some are `net10.0`-only). Use `./dotnet/eng/scripts/New-FilteredSolution.ps1` to generate a filtered solution: + +```powershell +# Generate a filtered solution for net472 and run tests +$filtered = ./dotnet/eng/scripts/New-FilteredSolution.ps1 -Solution dotnet/agent-framework-dotnet.slnx -TargetFramework net472 +dotnet test --solution $filtered --no-build -f net472 --ignore-exit-code 8 + +# Exclude samples and keep only unit test projects +./dotnet/eng/scripts/New-FilteredSolution.ps1 -Solution dotnet/agent-framework-dotnet.slnx -TargetFramework net10.0 -ExcludeSamples -TestProjectNameFilter "*UnitTests*" -OutputPath dotnet/filtered-unit.slnx +``` + +```bash +# Run tests via dotnet test (uses MTP under the hood) +dotnet test --project ./tests/Microsoft.Agents.AI.UnitTests -f net10.0 + +# Run tests with code coverage (Cobertura format) +dotnet test --project ./tests/Microsoft.Agents.AI.UnitTests -f net10.0 --coverage --coverage-output-format cobertura --coverage-settings ./tests/coverage.runsettings + +# Run tests directly via dotnet run (MTP native command line) +dotnet run --project ./tests/Microsoft.Agents.AI.UnitTests -f net10.0 + +# Show MTP command line help +dotnet run --project ./tests/Microsoft.Agents.AI.UnitTests -f net10.0 -- -? +``` diff --git a/dotnet/Directory.Packages.props b/dotnet/Directory.Packages.props index 1b1e0daa08..fa54be567c 100644 --- a/dotnet/Directory.Packages.props +++ b/dotnet/Directory.Packages.props @@ -11,19 +11,18 @@ - - + + - - - - - + + + + @@ -33,18 +32,19 @@ - + - + + - - + + - - - + + + @@ -63,12 +63,12 @@ - - - - + + + + - + @@ -76,11 +76,11 @@ - + - + @@ -94,24 +94,25 @@ - + - - + + - + + - + - + @@ -125,7 +126,7 @@ - + @@ -140,15 +141,14 @@ - - - - - - + + + + + @@ -187,4 +187,4 @@ runtime; build; native; contentfiles; analyzers; buildtransitive - \ No newline at end of file + diff --git a/dotnet/agent-framework-dotnet.slnx b/dotnet/agent-framework-dotnet.slnx index 9801ccc105..576d2c5c54 100644 --- a/dotnet/agent-framework-dotnet.slnx +++ b/dotnet/agent-framework-dotnet.slnx @@ -56,10 +56,30 @@ + + + + + + + + + + + + + + + + + + + + @@ -103,6 +123,7 @@ + @@ -284,8 +305,13 @@ + + + + + @@ -311,7 +337,6 @@ - @@ -348,6 +373,10 @@ + + + + @@ -413,6 +442,10 @@ + + + + @@ -506,4 +539,4 @@ - \ No newline at end of file + diff --git a/dotnet/agent-framework-release.slnf b/dotnet/agent-framework-release.slnf index ebd33c0767..1c8f477b16 100644 --- a/dotnet/agent-framework-release.slnf +++ b/dotnet/agent-framework-release.slnf @@ -14,6 +14,7 @@ "src\\Microsoft.Agents.AI.Declarative\\Microsoft.Agents.AI.Declarative.csproj", "src\\Microsoft.Agents.AI.DevUI\\Microsoft.Agents.AI.DevUI.csproj", "src\\Microsoft.Agents.AI.DurableTask\\Microsoft.Agents.AI.DurableTask.csproj", + "src\\Microsoft.Agents.AI.FoundryMemory\\Microsoft.Agents.AI.FoundryMemory.csproj", "src\\Microsoft.Agents.AI.Hosting.A2A.AspNetCore\\Microsoft.Agents.AI.Hosting.A2A.AspNetCore.csproj", "src\\Microsoft.Agents.AI.Hosting.A2A\\Microsoft.Agents.AI.Hosting.A2A.csproj", "src\\Microsoft.Agents.AI.Hosting.AGUI.AspNetCore\\Microsoft.Agents.AI.Hosting.AGUI.AspNetCore.csproj", diff --git a/dotnet/eng/MSBuild/Shared.props b/dotnet/eng/MSBuild/Shared.props index 9b4771a64e..94ac5b417b 100644 --- a/dotnet/eng/MSBuild/Shared.props +++ b/dotnet/eng/MSBuild/Shared.props @@ -8,6 +8,9 @@ + + + diff --git a/dotnet/eng/scripts/New-FilteredSolution.ps1 b/dotnet/eng/scripts/New-FilteredSolution.ps1 new file mode 100644 index 0000000000..de6a8f9d1d --- /dev/null +++ b/dotnet/eng/scripts/New-FilteredSolution.ps1 @@ -0,0 +1,145 @@ +#!/usr/bin/env pwsh +# Copyright (c) Microsoft.

In a production scenario you would raise the thresholds to match your model's context window and cost requirements. + +## Customizing the Pipeline + +### Using a single strategy + +If you only need one compaction strategy, pass it directly to `CompactionProvider` without wrapping it in a pipeline: + +```csharp +CompactionProvider provider = + new(new SlidingWindowCompactionStrategy(CompactionTriggers.TurnsExceed(20))); +``` + +### Ad-hoc compaction outside the provider pipeline + +`CompactionProvider.CompactAsync` applies a strategy to an arbitrary list of messages without an active agent session: + +```csharp +IEnumerable compacted = await CompactionProvider.CompactAsync( + new TruncationCompactionStrategy(CompactionTriggers.TokensExceed(8000)), + existingMessages); +``` + +### Using a different model for summarization + +The `SummarizationCompactionStrategy` accepts any `IChatClient`. Use a smaller, cheaper model to reduce summarization cost: + +```csharp +IChatClient summarizerChatClient = openAIClient.GetChatClient("gpt-4o-mini").AsIChatClient(); +new SummarizationCompactionStrategy(summarizerChatClient, CompactionTriggers.TokensExceed(4000)) +``` + +### Registering through `ChatClientAgentOptions` + +`CompactionProvider` can also be specified directly on `ChatClientAgentOptions` instead of calling `UseAIContextProviders` on the `ChatClientBuilder`: + +```csharp +AIAgent agent = agentChatClient + .AsBuilder() + .BuildAIAgent(new ChatClientAgentOptions + { + AIContextProviders = [new CompactionProvider(compactionPipeline)] + }); +``` + +This places the compaction provider at the agent level instead of the chat client level, which allows you to use different compaction strategies for different agents that share the same chat client. + +> Note: In this mode the `CompactionProvider` is not engaged during the tool calling loop. Agent-level `AIContextProviders` run before chat history is stored, so any synthetic summary messages produced by `CompactionProvider` can become part of the persisted history when using `ChatHistoryProvider`. If you want to compact only the request context while preserving the original stored history, register `CompactionProvider` on the `ChatClientBuilder` via `UseAIContextProviders(...)` instead of on `ChatClientAgentOptions`. diff --git a/dotnet/samples/02-agents/Agents/README.md b/dotnet/samples/02-agents/Agents/README.md index 116cbfc06b..4ac53ba246 100644 --- a/dotnet/samples/02-agents/Agents/README.md +++ b/dotnet/samples/02-agents/Agents/README.md @@ -44,6 +44,7 @@ Before you begin, ensure you have the following prerequisites: |[Deep research with an agent](./Agent_Step15_DeepResearch/)|This sample demonstrates how to use the Deep Research Tool to perform comprehensive research on complex topics| |[Declarative agent](./Agent_Step16_Declarative/)|This sample demonstrates how to declaratively define an agent.| |[Providing additional AI Context to an agent using multiple AIContextProviders](./Agent_Step17_AdditionalAIContext/)|This sample demonstrates how to inject additional AI context into a ChatClientAgent using multiple custom AIContextProvider components that are attached to the agent.| +|[Using compaction pipeline with an agent](./Agent_Step18_CompactionPipeline/)|This sample demonstrates how to use a compaction pipeline to efficiently limit the size of the conversation history for an agent.| ## Running the samples from the console diff --git a/dotnet/samples/02-agents/FoundryAgents/FoundryAgents_Evaluations_Step01_RedTeaming/Program.cs b/dotnet/samples/02-agents/FoundryAgents/FoundryAgents_Evaluations_Step01_RedTeaming/Program.cs index 60a859c28f..1e1e48d54b 100644 --- a/dotnet/samples/02-agents/FoundryAgents/FoundryAgents_Evaluations_Step01_RedTeaming/Program.cs +++ b/dotnet/samples/02-agents/FoundryAgents/FoundryAgents_Evaluations_Step01_RedTeaming/Program.cs @@ -60,7 +60,7 @@ Console.WriteLine();

Submit a request to the agent through the playground interface. For example, you may enter a prompt such as: "I need a hotel in Seattle from 2025-03-15 to 2025-03-18, budget under $200 per night." +4.

Open the VS Code Command Palette and run the `Microsoft Foundry: Deploy Hosted Agent` command. +2. Follow the interactive deployment prompts. The extension will help you select or create the container files it needs. +3. After deployment completes, the hosted agent appears under the `Hosted Agents (Preview)` section of the extension tree. You can select the agent there to view details and test it using the integrated playground. + +**What the deploy flow does for you:** + +- Creates or obtains an Azure Container Registry for the target project. +- Builds and pushes a container image from your workspace (the build packages the workspace respecting `.dockerignore`). +- Creates an agent version in Microsoft Foundry using the built image. If a `.env` file exists at the workspace root, the extension will parse it and include its key/value pairs as the hosted agent's environment variables in the create request (these variables will be available to the agent runtime). +- Starts the agent container on the project's capability host. If the capability host is not provisioned, the extension will prompt you to enable it and will guide you through creating it. + +## MSI Configuration in the Azure Portal + +This sample requires the Microsoft Foundry Project to authenticate using a Managed Identity when running remotely in Azure.
