CoreRT is an experimental .NET Core runtime and compiler toolchain optimized for ahead-of-time (AOT) compilation, producing native single-file executables or native libraries from managed .NET applications. The project has been superseded by the NativeAOT experiment in dotnet/runtimelab and is no longer actively developed.

Use cases

compile a .NET app into a native single-file executable
build a standalone native library from C# code consumable by other languages
deploy .NET apps without requiring a runtime install
reduce startup time of .NET console apps via AOT
compile ASP.NET Core apps to native binaries
experiment with running C# on WebAssembly

When to choose

you need native AOT compilation of .NET code and are studying the predecessor design
you want to compile .NET to a native library callable from C/C++
you are researching AOT runtime architecture in .NET

When to avoid

you want production AOT support - use NativeAOT in modern .NET instead
your app relies on Assembly.LoadFile, Reflection.Emit, or COM/WinRT interop
you need an actively maintained project
you need full garbage collection or exception handling via the CppCodeGen backend
