Release notes

Sourced from Microsoft.Extensions.AI's releases.

10.5.1

Version 10.5.1 of the Microsoft.Extensions.AI packages stabilizes CodeInterpreter, WebSearch, and ImageGeneration tool content types. The release adds new experimental tool search and OpenAI request policy hooks. And the OpenTelemetry gen-ai semantic conventions are updated to align with v1.41.

The 'aiagent-webapi' project template in Microsoft.Agents.AI.ProjectTemplates is updated to align with v1.3.0 of Agent Framework, updating the OpenTelemetry dependencies within the template projects as well.

Experimental API Changes

Now Stable

The following types previously emitted the MEAI001 experimental diagnostic and are now stable.

• CodeInterpreter and WebSearch tool content types are now stable #​7493
  • CodeInterpreterToolCallContent
  • CodeInterpreterToolResultContent
  • WebSearchToolCallContent
  • WebSearchToolResultContent
• ImageGeneration tool content types and tool are now stable #​7476
  • ImageGenerationToolCallContent
  • ImageGenerationToolResultContent
  • HostedImageGenerationTool
  • ImageGenerationOptions
  • ImageGenerationResponseFormat (the Hosted enum value remains experimental)
  • IImageGenerator and the rest of the image generation infrastructure also remain experimental

New Experimental APIs

The following new APIs emit the MEAI001 experimental diagnostic.

• New experimental API: HostedToolSearchTool with DeferredTools for tool-search-driven deferred tool loading #​7471
• New experimental API: OpenAIRequestPolicies extension hook for appending System.ClientModel.PipelinePolicy instances to outgoing OpenAI requests #​7495

Breaking Changes to Experimental APIs

• WebSearchToolResultContent.Results was renamed to Outputs as part of the stabilization in #​7493, aligning with CodeInterpreterToolResultContent.Outputs. The original Results property was included in version 10.4.0 and 10.5.0; this is a binary breaking change and consumers need to update to consume the updated property.

  WebSearchToolResultContent content = ...;
  - IList<AIContent>? items = content.Results;
  + IList<AIContent>? items = content.Outputs;
