C# Implementation Tracker

[silesmo]

This is an issue to track the implementation progress of C# with the mono runtime as well as the Native ahead of time LLVM compiled implementation.

• [x] Worlds
• [x] Interfaces
• [x] Functions
• [x] Integers
• [x] Floating point numbers
• [x] Strings
• [ ] Mono runtime tests - Dependent on (If we don't want to create 2 completely separate implementations to be able to support mono) https://github.com/dotnet/runtime/issues/86985 and https://github.com/dotnet/runtime/issues/86984
• [x] Native AoT LLVM runtime tests
• [x] Results - https://github.com/bytecodealliance/wit-bindgen/pull/807
• [x] Options
• [x] List - https://github.com/bytecodealliance/wit-bindgen/pull/807
• [x] Enum
• [x] Records
• [x] Flags
• [x] Variants - https://github.com/bytecodealliance/wit-bindgen/pull/807
• [x] Tuples
• [x] Resources
  • [x] Handles
  • [x] Static Functions
  • [x] Methods
• [ ] Usage instructions
• [ ] Put shared types in a C# lib - https://github.com/bytecodealliance/cm-dotnet
• [x] Runtime tests
• [x] Code Generation tests
  • [x] Enabled skipped tests in https://github.com/bytecodealliance/wit-bindgen/blob/5f903613cfb70364b89bbab92d62e85db16cf4e8/crates/csharp/tests/codegen.rs#L15
• bugs
  • [x] https://github.com/bytecodealliance/wit-bindgen/issues/777
  • [x] https://github.com/bytecodealliance/wit-bindgen/issues/778
  • [x] return pointer alignment - in some cases get error might be related to https://github.com/dotnet/runtimelab/pull/2531 (https://github.com/bytecodealliance/wit-bindgen/pull/807)
  • [ ] #963

future work:

• [ ] Streams
• [ ] Integration with GC proposal. Related: https://github.com/WebAssembly/gc/issues/77, https://github.com/dotnet/runtime/issues/94420
• [ ] Exception handling https://github.com/WebAssembly/exception-handling/tree/master
• [ ] Shared everything dynamic linking https://github.com/WebAssembly/component-model/blob/9c43f51ebf775e8397469a744d97c8575a7b7386/design/mvp/examples/SharedEverythingDynamicLinking.md

Lower priority items:

• [ ] fix c# namespacing to be idomatic c#. Right now things are a mix of lower and upper case
• [x] make options implementation use c# generics - Resolved in: https://github.com/bytecodealliance/wit-bindgen/pull/807
• [ ] fix imports so they are only included if needed
• [ ] create a cli option to generate the csproj and replace that for the tests.
• [ ] only use version info if required (https://github.com/bytecodealliance/wasmtime/pull/7656#issuecomment-1847540814)
