401a552735 .NET: Support ClaimsIdentity-based scoping of agent sessions (#5696)
* feat: Add DelegatingAgentSessionStore

Add helper for decorator pattern for AgentSessionStore

* feat: Add UserIdentityScopedSessionStore

Add support for using the ASP.Net Core ambient `ClaimsIdentity` User, along with a user-specified claim type to scope the session store based on authenticated identity.

* fix: Harden scope mapping

* fix: Add UserIdentityScopeSessionStoreOptions to avoid future breaking changes

* Split UserIdentityScopedSessionStore into a separate IsolationKeyProvider and IsolationKeyScopedSessionStore

* Add GetService<>() capabilities to interrogate AgentSessionStore delegation chain

* Harden default for A2A hosting by using an IsolationKeyScopedAgentSessionStore when no store is available.

* Pipe isolation through Hosting helper extension methods

* Add comment to samples about adding SessionIsolationKeyProvider

* Fix isolation key provider nullability semantics

* fix A2A defaults

* fixup

* remove unneeded keyProvider requirement test

* Add trust-model XML docs to AgentSessionStore, InMemoryAgentSessionStore, MapAGUI, A2A entry points

Quickstart

Basic Agent - .NET

using Azure.AI.OpenAI;
using Azure.Identity;
using Microsoft.Agents.AI;
using OpenAI.Responses;

var endpoint = Environment.GetEnvironmentVariable("AZURE_OPENAI_ENDPOINT")!;
var deploymentName = Environment.GetEnvironmentVariable("AZURE_OPENAI_DEPLOYMENT_NAME")!;

var agent = new AzureOpenAIClient(new Uri(endpoint), new AzureCliCredential())
    .GetResponsesClient(deploymentName)
    .AsAIAgent(name: "HaikuBot", instructions: "You are an upbeat assistant that writes beautifully.");

Console.WriteLine(await agent.RunAsync("Write a haiku about Microsoft Agent Framework."));
