# .NET Core Runtime (CoreRT)
This repo contains the .NET Core runtime optimized for AOT compilation

## Platform Support

This is a work in progress. The current state of platform support:
- Windows x64 w/ RyuJIT codegen: Simple ASP.NET apps compile and run with some [workarounds](https://github.com/dotnet/corert/issues/4444#issuecomment-328206168)
- MacOS and Linux x64 w/ RyuJIT codegen: Same as Windows, the libraries are less complete.
- Linux ARM w/ RyuJIT codegen: ["Hello world"](https://github.com/dotnet/coreclr/pull/14090#issuecomment-330933768)
- CppCodeGen (targets all platforms that support C++): Simple C# programs. The big missing features are [reflection](https://github.com/dotnet/corert/issues/2035), [garbage collection](https://github.com/dotnet/corert/issues/2033) and [exception handling](https://github.com/dotnet/corert/issues/910).
- WebAssembly: Early prototype that compiles and runs very trivial programs only. Many features are [not yet implemented](https://github.com/dotnet/corert/issues?q=is%3Aissue+is%3Aopen+label%3Aarch-wasm).
