Bump the dotnet group with 3 updates by dependabot[bot] · Pull Request #76 · preechapon250/.NET-docs

Abstractions for remote MCP servers; response/approval flow support via new experimental types
Function approvals via new experimental types (e.g., ApprovalRequiredAIFunction, user input/approval request & response content).
Reasoning text streaming for OpenAI Responses ChatClient streaming.
AIFunction split into a base class to improve extensibility.
IChatReducer moved to Microsoft.Extensions.AI.Abstractions.
Updated to OpenAI 2.4.0 and genai standard convention 1.37.
Coalescing logic now treats ChatMessage.Role changes as new messages.
GetResponseAsync<T> now reads only the last message (bug fix).
OpenTelemetry ChatClient/EmbeddingGenerator logs raw additional properties (no key mangling).
Fixed empty annotated text chunk handling in streaming with OpenAI Assistants.

Telemetry & Diagnostics

HTTP diagnostics log query string params with proper redaction (emitted on url.query).
server.address telemetry emits host only (per OpenTelemetry semantic conventions).
Heuristics added to detect well-known model hosts.
Resource monitoring can consider Environment.CpuUsage.

Mark RunSessionHandler experimental (MCPEXP002) #1383
- HttpServerTransportOptions.RunSessionHandler is now annotated with [Experimental("MCPEXP002")]
- Code that references RunSessionHandler will produce a compile-time warning (or error with TreatWarningsAsErrors); suppress with #pragma warning disable MCPEXP002
- Consider using ConfigureSessionOptions as an alternative; RunSessionHandler may be removed or change signatures in a future release

Full Changelog: modelcontextprotocol/csharp-sdk@v1.0.0-rc.1...v1.0.0

1.0.0-rc.1

This release candidate completes a full API surface area audit ahead of the 1.0.0 stable release, with more changes to public APIs to ensure consistency and long-term maintainability. Protocol DTO types are updated to match the MCP specification, deprecated filter APIs are removed, and bug fixes improve transport reliability and JSON handling.

Breaking Changes

Refer to the C# SDK Versioning documentation for details on versioning and breaking change policies.

Address asymmetry in McpServerHandlers/McpClientHandlers and make all filter properties settable #1337
- Seals McpClientHandlers to match the already-sealed McpServerHandlers
- Makes McpServerOptions.Handlers, McpServerOptions.Filters, and all IList<T> filter properties settable with null validation
Remove server back-references from protocol DTO types #1345
- Removes Tool.McpServerTool, Prompt.McpServerPrompt, Resource.McpServerResource, and ResourceTemplate.McpServerResource properties
- Use McpServerPrimitiveCollection.TryGetPrimitive() for name-based lookups instead
Make Tool.Name required to match other protocol types #1351
- Adds required modifier to Tool.Name, matching Prompt.Name, Resource.Name, and other IBaseMetadata implementations
- Callers must now specify Name in object initializers
Make LoggingMessageNotificationParams.Data required per MCP spec #1353
- Changes LoggingMessageNotificationParams.Data from JsonElement? to required JsonElement per the MCP specification
Fix CreateMessageRequestParams.Metadata type to JsonObject #1354
- Changes CreateMessageRequestParams.Metadata from JsonElement? to JsonObject? to match all other _meta/Meta properties in the SDK
Normalize CallToolResult.StructuredContent to JsonElement? #1357
- Changes CallToolResult.StructuredContent from JsonNode? to JsonElement? for consistency with the rest of the SDK
- Use JsonSerializer.SerializeToElement() to produce a JsonElement
Unify service configuration for ISseEventStreamStore, IMcpTaskStore, and ISessionMigrationHandler #1362
- Consistent options + DI pattern: explicit options property > DI resolution
Add explicit [Experimental] protected constructors to McpClient and McpServer #1363
- Protected constructors on McpClient and McpServer now require suppressing MCPEXP002 to subclass
Remove MCP9002 obsolete APIs and document obsolete diagnostics #1366
- Removes the 13 AddXxxFilter extension methods on IMcpServerBuilder (e.g. AddCallToolFilter, AddListToolsFilter) that were deprecated under diagnostic MCP9002

0.9.0-preview.2

This release focuses on API surface consistency and correctness ahead of 1.0.0. Public collection properties are now typed as IList<T> instead of concrete List<T> or T[], and Root.Meta is aligned with the rest of the protocol DTOs by using JsonObject?. Other improvements include new experimental Extensions support for capabilities, missing ResourceLinkBlock properties, improved mimeType handling, and several documentation and test reliability fixes.

We plan to release the stable 1.0.0 release early in the week of February 23, 2026.

Breaking Changes

Refer to the C# SDK Versioning documentation for details on versioning and breaking change policies.

Replace concrete collection types with interfaces in public API surface #1326
- List<T> and T[] properties on ProtectedResourceMetadata, ToolResultContentBlock, ListTasksResult, and DynamicClientRegistrationResponse changed to IList<T>. Replace .Length with .Count and cast to List<T> if List<T>-specific members are needed.
Fix Root.Meta to use JsonObject instead of JsonElement #1341
- Root.Meta changed from JsonElement? to JsonObject?. Replace meta.Value.GetProperty("key").GetString() with (string?)meta["key"].
Make UrlElicitationRequiredErrorData.Elicitations consistent with other Protocol DTOs #1335
- Elicitations changed from IReadOnlyList<ElicitRequestParams> with init to IList<ElicitRequestParams> with set. Code using List<T> is unaffected since it implements both interfaces.
