Ben Thomas c79f886dc3 .NET: Align Foundry sample environment variables and credentials. (#6422)
* dotnet: refresh Foundry sample guidance

Carry forward the still-relevant sample guidance and Foundry-specific documentation fixes from the old stacked sample migration work, adapted to the current repo layout and policy.

* dotnet: drop SAMPLE_GUIDELINES.md from this PR

Defer the guidelines doc and its cross-link to a follow-on PR to avoid broken-link failures in CI.

AgentWithCodeAct_Step02_ToolEnabled

Demonstrates adding provider-owned tools to HyperlightCodeActProvider. Those tools are only available to code running inside the sandbox via call_tool("<name>", ...) — they are never exposed to the model as direct tools. This lets the model orchestrate multiple tool calls in a single Python block.

One tool (send_email) is wrapped in ApprovalRequiredAIFunction, which causes the entire execute_code invocation to require user approval when that tool is configured.

Configuration

Variable Description
AZURE_OPENAI_ENDPOINT Azure OpenAI endpoint. Required.
AZURE_OPENAI_DEPLOYMENT_NAME Azure OpenAI deployment. Defaults to gpt-5.4-mini.
HYPERLIGHT_PYTHON_GUEST_PATH Absolute path to the Hyperlight Python guest module (.wasm or .aot file). Required.

Run

cd AgentWithCodeAct_Step02_ToolEnabled
dotnet run

Planned follow-up

A more realistic "upload a file (e.g. an Excel workbook), have the agent analyze it with code" sample is planned as a separate step that will use HostInputDirectory together with a guest tool capable of reading the uploaded file. It will be added in a follow-up PR once the corresponding guest module support is in place.
