Updated Microsoft.Extensions.ServiceDiscovery from 10.7.0 to 10.9.0.

Release notes

Sourced from Microsoft.Extensions.ServiceDiscovery's releases.

10.9.0

Version 10.9.0 is headlined by changes in these areas:

• AI: New experimental routing APIs center on the abstract RoutingChatClient base class, with SemanticRoutingChatClient as a concrete semantic-routing implementation. Separately, the abstract FailoverChatClient specialization and its concrete OrderedFailoverChatClient implementation add failover routing.
• AI Evaluation: The generated report gains redesigned Overview, Cases, History, and Comparison views.
• ASP.NET Core and HTTP diagnostics: The release adds HTTP request latency log enrichment and fixes configuration binding, response-body logging, request-path redaction, and resilience package version handling.
• Source-generated logging and service discovery: Fixes cover classification type qualification, thread-local state cleanup, and DNS query suffix handling.

Experimental API Changes

New Experimental APIs

• New experimental API: HTTP request latency log enrichment (EXTEXP0013) #​7602
• New experimental API: Chat client routing and failover (MEAI001) #​7662

What's Changed

AI (Microsoft.Extensions.AI, Microsoft.Extensions.AI.Abstractions, and Microsoft.Extensions.AI.OpenAI)

• Add extensible chat client routing #​7662 by @​joshuajyue (co-authored by @​Copilot)
• Pass the request's options to the selected client #​7685 by @​joshuajyue (co-authored by @​jozkee @​Copilot)
• AI.Abstractions: fix ExcludeFromSchema dropped under concurrent AIFunction creation #​7677 by @​jozkee (co-authored by @​Copilot)
• Cap OpenAI dependency version (b10f9c0) by @​jeffhandley (co-authored by @​Copilot)

Note: Microsoft.Extensions.AI.OpenAI constrains its dependency for OpenAI to 2.12.x, preventing OpenAI updates to 2.13.0+ due to an incompatibility. We expect to release Microsoft.Extensions.AI.OpenAI version 10.9.1 during the week of August 17 to address this issue.

HTTP Resilience and Diagnostics (Microsoft.Extensions.Http.Resilience and Microsoft.Extensions.Http.Diagnostics)

• Fix Grpc.Net.ClientFactory version range check - Fixes #​7565 #​7566 by @​Ghost93
• Fix response body logging under debugger #​7678 by @​Rimobul
• Redact outgoing path when route is unknown #​7687 by @​Rimobul
• Fix HTTP client logging config binding #​7691 by @​Rimobul

ASP.NET Core Extensions (Microsoft.AspNetCore.Diagnostics.Middleware)

• Rename HttpLatencyTelemetry extensions class and drop redundant TFM guard #​7645 by @​EasyL0ver (co-authored by @​Copilot)
• Add HTTP request latency log enricher (experimental) #​7602 by @​EasyL0ver (co-authored by @​Copilot)

Logging Source Generator (Microsoft.Gen.Logging)

• [Microsoft.Gen.Logging] Clear thread-local state when logging throws #​7682 by @​Rimobul

• [Microsoft.Extensions.AI.Evaluation.Reporting] Evaluation report redesign #​7609 by @​grafanaKibana

Project Templates (Microsoft.McpServer.ProjectTemplates)

• Remove MCP server project template #​7680 by @​jeffhandley (co-authored by @​Copilot)

10.8.4

This servicing update refreshes the .NET AI project templates ahead of the July 30, 2026 retirement of GitHub Models — removing the GitHub Models provider option and updating template dependencies.

As a result, both the AI Chat Web (aichatweb) and AI Agent Web API (aiagent-webapi) templates now require the AI service provider to be chosen explicitly via --provider; there is no longer a default. One of the following must be selected:

• --provider azureopenai — Azure OpenAI
• --provider ollama — Ollama (for local development)
• --provider openai — OpenAI Platform

Packages in this release

Package	Version
Microsoft.Extensions.AI.Templates	10.8.4-preview.3.26379.3
Microsoft.Agents.AI.ProjectTemplates	1.13.0-preview.1.26379.3

What's Changed

Project templates

• Removed the GitHub Models provider from the AI Chat Web and AI Agent Web API templates, ahead of GitHub Models being fully retired on July 30, 2026. The --provider option is now required with no default (#​7667).
• Updated AI template dependencies — bumped Aspire.Hosting.AppHost to 13.4.6 and CommunityToolkit.VectorData.SqliteVec to 1.0.0-preview.4 (aligned System.Linq.AsyncEnumerable to 10.0.9), replacing earlier workaround package pins (#​7639).

10.8.3

Packages in this release

Package	Version
Microsoft.Extensions.AI	10.8.3
Microsoft.Extensions.AI.Abstractions	10.8.3
Microsoft.Extensions.AI.OpenAI	10.8.3

Experimental API Changes

Experimental API behavior updates

• Updated serialization behavior for experimental ToolApprovalRequestContent.RequiresConfirmation so it no longer leaks into consumer source-generated AIContent JSON metadata unless approval APIs are intentionally used (#​7659).

What's Changed

AI abstractions and serialization

• Fixed MEAI001 leakage from RequiresConfirmation in source-generated AIContent contexts by using an internal JSON-included backing member while keeping the public experimental member ignored for source-generation metadata (#​7659).

Test Improvements

• Added stabilization regression coverage to verify consumer source-generated List<AIContent> contexts compile and round-trip without requiring MEAI001 suppression (#​7659).

10.8.2

This servicing release updates Microsoft.Extensions.VectorData.ConformanceTests to 10.8.2 and includes targeted test framework migration fixes.

Packages in this release

Package	Version	Note
Microsoft.Extensions.VectorData.Abstractions	10.8.2	Published August 7, 2026
Microsoft.Extensions.VectorData.ConformanceTests	10.8.2

Update: August 7, 2026
The Microsoft.Extensions.VectorData.Abstractions package was initially excluded from this release by mistake. Because Microsoft.Extensions.VectorData.ConformanceTests has a dependency on Microsoft.Extensions.VectorData.Abstractions, that led to failures when updating to Microsoft.Extensions.VectorData.ConformanceTests 10.8.2.

Microsoft.Extensions.VectorData.Abstractions was published August 7, 2026 to resolve that issue.

What's Changed

AI

• Move Microsoft.Extensions.VectorData.ConformanceTests to xUnit 3 #​7636 by @​adamsitnik (co-authored by @​Copilot)

10.8.1

This servicing release updates the Microsoft.Extensions.AI, Microsoft.Extensions.AI.Abstractions, and Microsoft.Extensions.AI.OpenAI packages to 10.8.1 with two targeted fixes: correct tool-call/tool-result ordering when resuming approval-gated functions with service-managed chat history, and preservation of the OpenAI Responses reasoning item id for stateless (store=false) encrypted reasoning.

Packages in this release

Package	Version
Microsoft.Extensions.AI	10.8.1
Microsoft.Extensions.AI.Abstractions	10.8.1
