Release notes

6.1.6

This update brings the following changes since the 6.1.5 release:

Added

WAM broker support for the supported Entra ID authentication modes (Windows only)

What Changed:

• Added support for the Web Account Manager (WAM) broker for the supported Microsoft Entra ID authentication modes. A new ActiveDirectoryAuthenticationProviderOptions options bag and a corresponding ActiveDirectoryAuthenticationProvider(ActiveDirectoryAuthenticationProviderOptions options) constructor were introduced, exposing a UseWamBroker property (alongside ApplicationClientId and DeviceCodeFlowCallback).
  (#​4288, #​4387)
• Added a cross-platform SetParentActivityOrWindowFunc(Func<object> parentActivityOrWindowFunc) method so callers can supply a parent window handle on Windows or a parent Activity/UIViewController on Android/iOS/MAUI.

Who Benefits:

• Applications using ActiveDirectoryInteractive and other supported Entra ID authentication modes on Windows benefit from the WAM broker's improved security (tokens are brokered by the OS), single sign-on with the logged-in Windows account, and support for Conditional Access and Windows Hello.

Impact:

• When you supply your ApplicationClientId, WAM is opt-in via ActiveDirectoryAuthenticationProviderOptions.UseWamBroker. Consider enabling it when you want OS-brokered tokens, single sign-on with the signed-in Windows account, Windows Hello, and Conditional Access support.
• UseWamBroker is a Windows-only setting and has no effect on non-Windows platforms, where interactive Entra ID flows always use the system browser.
• Prefer the new options-bag constructor over the positional-argument overloads in new code.

var options = new ActiveDirectoryAuthenticationProviderOptions
{
    ApplicationClientId = "<your-app-client-id>",
    // Enable WAM (Windows only) for OS-brokered tokens, SSO, Windows Hello, and Conditional Access.
    UseWamBroker = true,
};
var provider = new ActiveDirectoryAuthenticationProvider(options);
// Supply the parent window/activity that owns the interactive sign-in prompt.
provider.SetParentActivityOrWindowFunc(() => parentWindowHandle);
SqlAuthenticationProvider.SetProvider(SqlAuthenticationMethod.ActiveDirectoryInteractive, provider);

Changed

Hardened TDS token parsing with data-length bounds checks

What Changed:

• Added bounds checking when parsing TDS token data lengths. The parser now validates the declared length of incoming token data against the available buffer before reading, rejecting malformed or out-of-range length values instead of reading past the intended boundary.
  (#​4340, #​4359)

Who Benefits:

• All consumers benefit from improved resilience against malformed or hostile TDS responses. A server (or man-in-the-middle) sending an invalid token length can no longer drive the parser to read beyond the declared payload.

Impact:
... (truncated)

6.1.5

This update brings the following changes since the 6.1.4 release:

Fixed

• Fixed a connection performance regression where SPN (Service Principal Name) generation was triggered for non-integrated authentication modes (e.g., SQL authentication) on the native SNI path, causing unnecessary DNS lookups and significantly slower connection times. Only affects .NET on Windows (not .NET Framework). (#​3523, #​3946)
• Fixed ExecuteScalar to properly propagate errors when the server sends data followed by an error token. Previously, errors such as conversion failures during WHERE clause evaluation were silently consumed during SqlDataReader.Close() instead of being thrown to the caller, which could result in transactions being unexpectedly zombied. (#​3736, #​3947)
• Fixed SqlDataReader.GetFieldType and SqlDataReader.GetProviderSpecificFieldType to return the correct type (SqlVector<float>) for vector float32 columns. Previously, these methods did not follow the same type-resolution logic as GetValue, returning an incorrect type for vector columns. (#​4104, #​4151)

6.1.4

This update brings the following changes since the 6.1.3 release:

Fixed

• Fixed NullReferenceException issue with SqlDataAdapter when processing batch scenarios where certain SQL RPC calls may not include system parameters.
  (#​3877)
• Fixed connection pooling issue where extra connection deactivation was causing active connection counts to go negative.
  (#​3776)

Added

AppContext Switch for enabling MultiSubnetFailover

What Changed:

• Added new AppContext switch Switch.Microsoft.Data.SqlClient.EnableMultiSubnetFailoverByDefault to set MultiSubnetFailover=true by default in connection string.
  (#​3851)

Who Benefits:

• Applications that need MultiSubnetFailover enabled globally without modifying connection strings.

Impact:

• Applications can now enable MultiSubnetFailover globally using one of the following methods:

// In application code
AppContext.SetSwitch("Switch.Microsoft.Data.SqlClient.EnableMultiSubnetFailoverByDefault", true);

// In runtimeconfig.json
{
  "configProperties": {
    "Switch.Microsoft.Data.SqlClient.EnableMultiSubnetFailoverByDefault": true
  }
}

<!-- In App.Config -->
<runtime>
  <AppContextSwitchOverrides value="Switch.Microsoft.Data.SqlClient.EnableMultiSubnetFailoverByDefault=true" />
</runtime>

Changed

• Optimized SqlStatistics execution timing by using Environment.TickCount instead of more expensive timing mechanisms.
  ... (truncated)

6.1.3

This update includes the following changes since the 6.1.2 release:

Added

App Context Switch for Ignoring Server-Provided Failover Partner

What Changed:

• A new app context switch Switch.Microsoft.Data.SqlClient.IgnoreServerProvidedFailoverPartner was introduced to let the client ignore server-provided failover partner info in Basic Availability Groups (BAGs). When the switch is enabled, only the failover partner specified in the connection string is used; server-supplied partner values are skipped. This context switch was introduced in PR #​3702.

Who Benefits:

• Applications connecting to SQL Server BAGs using TCP and custom ports, especially where the server's provided partner name lacks the protocol, host, or port. This avoids connection failures when the server-provided partner is incompatible or incomplete.
• Teams who manage availability groups and rely on client-side control of failover behavior in heterogeneous networking environments.

Impact:

• If your environment might be affected (i.e., you operate a BAG with custom ports, or have experienced failures after failover), you can enable the new switch in your application:

AppContext.SetSwitch("Switch.Microsoft.Data.SqlClient.IgnoreServerProvidedFailoverPartner", true);

• Then, ensure your connection string includes your preferred failover partner (with correct tcp:host,port) so that the client uses that instead of the server's suggestion.
• Without enabling this, by default, the client continues to prefer the server-provided partner, maintaining backwards compatibility.

Fixed

• Fixed an issue to ensure reliable metrics initialization during startup, preventing missed telemetry when EventSource is enabled early. (#​3718)

Target Platform Support

• .NET Framework 4.6.2+ (Windows ARM64, Windows x86, Windows x64)
• .NET 8.0+ (Windows x86, Windows x64, Windows ARM64, Windows ARM, Linux, macOS)

• Fixed an issue where a Custom SqlClientAuthenticationProvider was being overwritten by default implementation. #​3651
• Fixed a concurrency issue in connection pooling where the number of active connections could be lower than the configured maximum pool size. #​3653

  ... (truncated)

10.7.0

v10.7.0 graduates the Microsoft.Extensions.Diagnostics.ResourceMonitoring.Kubernetes package to stable. The package registers a Kubernetes-aware ResourceQuotaProvider that reads the pod's CPU and memory requests and limits and exposes them to Microsoft.Extensions.Diagnostics.ResourceMonitoring as baseline and maximum quotas, which then feed the request and limit dimensions of the published resource utilization metrics. The companion ResourceQuota and ResourceQuotaProvider types in Microsoft.Extensions.Diagnostics.ResourceMonitoring graduate to stable in the same change so that consumers can implement custom quota providers without taking an experimental dependency.

On the AI side, Microsoft.Extensions.AI.OpenAI moves to OpenAI 2.11.0 and fixes a deserialization bug in ToolJson.AdditionalProperties so that JSON Schema additionalProperties values shaped as sub-schema objects (for example {"type":"string"}) are preserved instead of throwing during deserialization. HostedFileContent.SizeInBytes and HostedFileContent.CreatedAt graduate to stable since both values are consistently available across hosted-file providers, while Purpose and Scope remain experimental as provider-shaped vocabulary. FunctionInvokingChatClient drops a backward-compat path that auto-marked ToolApprovalResponseContent entries with InformationalOnly: true; consumers that need to continue accepting sessions serialized before #​7468 can use the sample ApprovalHistoryNormalizingChatClient middleware added in the test project.

Experimental API Changes

What's Changed

Microsoft.Extensions.VectorData.Abstractions

• Minor fixes to MEVD.Abstractions: correct StorageName behavior when external serialization is enabled, and disable a warning for net462. (by @​roji in #​7475)

Full Changelog: dotnet/extensions@v10.5.1...v10.5.2

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.

Microsoft.Agents.AI.ProjectTemplates	1.3.0-preview.1.26251.3

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;

... (truncated)

10.5.0

HTTP Logging Middleware APIs in Microsoft.AspNetCore.Diagnostics.Middleware are now stable. This release also transfers Microsoft.Extensions.VectorData.Abstractions and Microsoft.Extensions.VectorData.ConformanceTests from the Semantic Kernel repository into dotnet/extensions, jumping from 10.1.0 to 10.5.0 for consistent versioning. The release also delivers fixes across the AI libraries, AI Evaluation, and Service Discovery.

Breaking Changes

1. Rename VectorStoreVectorAttribute constructor parameter #​7460
   • The Dimensions parameter was renamed to dimensions (lowercase). This is a source-breaking change only — binary compatibility is preserved.
   • If you use the named argument syntax new VectorStoreVectorAttribute(Dimensions: 1536), update it to new VectorStoreVectorAttribute(dimensions: 1536).

Experimental API Changes

Now Stable

• HTTP Logging Middleware APIs are now stable (previously EXTEXP0013): AddHttpLogEnricher<T>, IHttpLogEnricher, and RequestHeadersLogEnricherOptions.HeadersDataClasses #​7380

10.3.0

Experimental API Changes

Now Stable

• IChatReducer interface — graduated from experimental to stable. The interface is now stable; concrete implementations (MessageCountingChatReducer, SummarizingChatReducer, ReducingChatClient) remain experimental. #​7235 by @​jeffhandley
• FunctionCallContent and FunctionResultContent unsealed — changed from sealed class to class, enabling derivation. #​7229 by @​stephentoub (co-authored by @​Copilot)

Breaking Changes to Experimental APIs

• Experimental diagnostic ID reorganization — the blanket MEAI001 diagnostic ID was split into feature-specific constants. OpenAI-specific experimental APIs now use OPENAI001, OPENAI002, or SCME0001 instead of MEAI001. Consumers who suppressed MEAI001 for OpenAI APIs may need to suppress OPENAI001/OPENAI002 instead. #​7116 by @​jeffhandley (co-authored by @​Copilot), #​7235 by @​jeffhandley

New Experimental APIs

• Chat reduction implementations — MessageCountingChatReducer, SummarizingChatReducer, ReducingChatClient, and UseChatReducer builder extension. #​7235 by @​jeffhandley
• OpenAI Responses/Assistants/Realtime/Image/Audio integrations — assigned feature-specific experimental diagnostic IDs (OPENAI001, OPENAI002). #​7235 by @​jeffhandley
• ImageGenerationToolCallContent and ImageGenerationToolResultContent — added to JSON serialization infrastructure. #​7275 by @​stephentoub (co-authored by @​Copilot)

10.7.0

v10.7.0 graduates the Microsoft.Extensions.Diagnostics.ResourceMonitoring.Kubernetes package to stable. The package registers a Kubernetes-aware ResourceQuotaProvider that reads the pod's CPU and memory requests and limits and exposes them to Microsoft.Extensions.Diagnostics.ResourceMonitoring as baseline and maximum quotas, which then feed the request and limit dimensions of the published resource utilization metrics. The companion ResourceQuota and ResourceQuotaProvider types in Microsoft.Extensions.Diagnostics.ResourceMonitoring graduate to stable in the same change so that consumers can implement custom quota providers without taking an experimental dependency.

On the AI side, Microsoft.Extensions.AI.OpenAI moves to OpenAI 2.11.0 and fixes a deserialization bug in ToolJson.AdditionalProperties so that JSON Schema additionalProperties values shaped as sub-schema objects (for example {"type":"string"}) are preserved instead of throwing during deserialization. HostedFileContent.SizeInBytes and HostedFileContent.CreatedAt graduate to stable since both values are consistently available across hosted-file providers, while Purpose and Scope remain experimental as provider-shaped vocabulary. FunctionInvokingChatClient drops a backward-compat path that auto-marked ToolApprovalResponseContent entries with InformationalOnly: true; consumers that need to continue accepting sessions serialized before #​7468 can use the sample ApprovalHistoryNormalizingChatClient middleware added in the test project.

Full Changelog: dotnet/extensions@v10.5.2...v10.6.0

10.5.2

This patch release ships a single fix to Microsoft.Extensions.VectorData.Abstractions, correcting StorageName resolution when external serialization is enabled. Microsoft.Extensions.VectorData.ConformanceTests, Microsoft.Extensions.AI.Abstractions, Microsoft.Extensions.AI, and Microsoft.Extensions.AI.OpenAI are published alongside it for version coherency — they contain no code changes from 10.5.1.

Packages in this release

Package	Version
Microsoft.Extensions.VectorData.Abstractions	10.5.2
Microsoft.Extensions.VectorData.ConformanceTests	10.5.2
Microsoft.Extensions.AI.Abstractions	10.5.2
Microsoft.Extensions.AI	10.5.2
Microsoft.Extensions.AI.OpenAI	10.5.2

What's Changed

Microsoft.Extensions.VectorData.Abstractions

• Minor fixes to MEVD.Abstractions: correct StorageName behavior when external serialization is enabled, and disable a warning for net462. (by @​roji in #​7475)

Full Changelog: dotnet/extensions@v10.5.1...v10.5.2

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.

Packages in this release

Package	Version
Microsoft.Extensions.AI	10.5.1
Microsoft.Extensions.AI.Abstractions	10.5.1
Microsoft.Extensions.AI.OpenAI	10.5.1
Microsoft.Extensions.AI.Templates	10.5.1-preview.3.26251.3
Microsoft.Agents.AI.ProjectTemplates	1.3.0-preview.1.26251.3

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;

... (truncated)

10.5.0

HTTP Logging Middleware APIs in Microsoft.AspNetCore.Diagnostics.Middleware are now stable. This release also transfers Microsoft.Extensions.VectorData.Abstractions and Microsoft.Extensions.VectorData.ConformanceTests from the Semantic Kernel repository into dotnet/extensions, jumping from 10.1.0 to 10.5.0 for consistent versioning. The release also delivers fixes across the AI libraries, AI Evaluation, and Service Discovery.

Breaking Changes

1. Rename VectorStoreVectorAttribute constructor parameter #​7460
   • The Dimensions parameter was renamed to dimensions (lowercase). This is a source-breaking change only — binary compatibility is preserved.
   • If you use the named argument syntax new VectorStoreVectorAttribute(Dimensions: 1536), update it to new VectorStoreVectorAttribute(dimensions: 1536).

Experimental API Changes

Now Stable

• HTTP Logging Middleware APIs are now stable (previously EXTEXP0013): AddHttpLogEnricher<T>, IHttpLogEnricher, and RequestHeadersLogEnricherOptions.HeadersDataClasses #​7380
