* Improve progress reporting
- Enable injecting an `IProgress<>` into a tool call to report progress when the client has supplied a progress token
- Add a custom type for ProgressToken and ProgressNotification to map to the schema
- Simplify RequestId to match ProgressToken's shape
- Serialize StdioClientTransport's SendMessageAsync implementation
- Add strongly-typed names for all request methods
- Change all request IDs created by McpJsonRpcEndpoint to include a guid for that endpoint
* Address PR feedback
* Supporting resource templates with read resource callback
Fixes#123
* Aligning the resource data structures with the 2024-11-05 schema
- Introducing separate classes for Text and Blob ResourceContents
- Custom JSON converter to allow those types to be returned, making it easier to follow the type system against the spec
- Updated tests
* Apply suggestions from code review

- This also paves the way for better multi-session support
- We should definitely rethink names for the transport API
- For now, I kept the names similar as possible, so we can
focus on the API shape

* Fix some issues with Native AOT
- An anonymous type was being used in McpClient for the initialize result message. Switched to use the type for that purpose that already existed.
- A bunch of the request params / result types were not in the source context or referenced from types that were or from custom converters. Added all the request/result types to the context.
- Improved the warning message for WithTools.
* Overhaul tool handling
- Renames [McpTool{Type}] to [McpServerTool{Type}], in order to distinguish representations of tools on the server from tools on the client.
- Enables [McpServerTool] methods to have arguments injected from DI, as well as a specific set of types from the implementation directly, like IMcpServer.
- Renames WithTools to WithToolsFromAssembly.
- All of the WithToolsXx methods now publish each individual McpServerTool into DI; other code can do so as well. The options setup code gathers all of the tools from DI and combines them into a collection which is then stored in McpServerOptions and used to construct the server.
- The server tools specified via DI as well as manually-provided handlers, using CallToolHandler as a fallback in case the requested tool doesn't exist in the tools collection, and ListToolsHandler augments the information for whatever tools exist.
- The tools are stored in McpServerOptions in a new McpServerToolCollection type, which is a thread-safe container that exposes add/removal notification. Adding/removing tools triggers a change notification that in turn sends a notification to the client about a tools update.
- The ServerOptions are exposed from the server instance.
- Removed cursor-based APIs from McpClientExtensions.
- Changed McpClientExtensions APIs to return `Task<IList<...>` rather than `IAsyncEnumerable<...>`.
I'm sure this will need to evolve further before we're "done", but it's a significant improvement from where we are now. One area I'm not super happy with is the notifying collection; that might work ok for a stdio server, where you can grab the created collection from the server's options and mutate it, but I don't know how well that's going to work for sse servers.
* Make McpServerTool{Collection} extensible
* Fix README.md example
* Add notifications test
* Address feedback
* fix: Enforce UTF-8 encoding for stdio transport
This change replaces the default system encoding with an explicit UTF8Encoding (without BOM)
for both client and server transports. This ensures proper handling of Unicode characters,
including Chinese characters and emoji.
- Use UTF8Encoding explicitly for StreamReader and StreamWriter.
- Add tests for Chinese characters ("上下文伺服器") and emoji (🔍🚀👍) to confirm the fix.
Fixes#35.
* Remove relaxed JSON encoder
* Address PR feedback

The server was throwing if this handler wasn't specified, and it should probably be optional anyway.
