.NET Runtime Lab

This repo is for experimentation and exploring new ideas that may or may not make it into the main dotnet/runtime repo. Encouraging .NET Runtime Experiments describes reasons that motivated creating this repository.

Active Experimental Projects

Currently, this repo contains the following experimental projects:

DllImportGenerator - Roslyn Source Generator used for generating P/Invoke IL stubs.
JsonCodeGen - Code generation for JSON.
NativeAOT - .NET runtime optimized for ahead of time compilation.
Utf8String - A new UTF-8 String data type in the runtime.
RegexSRM - Incorporating MSR's Symbolic Regex Matcher (SRM) into System.Text.RegularExpressions
FreeBSD - Port of .NET runtime to FreeBSD
s390x - Port of .NET runtime (Mono) to the s390x architecture
NativeAOT-LLVM - LLVM generation for Native AOT compilation (including Web Assembly)
NativeAOT-interpreter - Native AOT with interpreter to support runtime codegen
ManagedQuic - Fully managed implementation of QUIC protocol
