kodraus/bootleg-dotnet repository overview

GitHub repository⁠

A local debug build of some of the fundamental pieces of a dotnet toolchain:

• csc: A C# to IL compiler from roslyn⁠.
• ilc: An IL to native code compiler from corert⁠.
• corerun: An entry point to the runtime from coreclr⁠.
• ildasm: A tool for examining the IL in managed DLLs from coreclr⁠.
• crossgen: An IL to Ready-to-run DLL compiler from coreclr⁠ (based on corert⁠).
• r2rdump: A tool for examining the native code in Ready-to-run DLLs from coreclr⁠.

Other sources include:

• corefx⁠ for build-time core libraries.
• llilc⁠ for LLVM dependencies used by ilc and crossgen.
• diagnostics⁠ for debugging managed code with lldb.

Some tools you might be used to working with are notably absent:

• dotnet
• msbuild
• nuget

That seems pretty limiting... but there's still plenty of capability packed into the tools that are there! To give you an idea, this project includes its own bootleg dotnet-like CLI built on the same tools listed previously that dotnet itself uses. It's called dnb (which stands for Azure .NET Bootleg Core 5, to fit with expected .NET 5 naming):

$ dnb
Azure .NET Bootleg Core 5

Usage: dnb restore
Usage: dnb build [--restore] [--kind=il|r2r|aot]
Usage: dnb run [--restore] [--build=il|r2r|aot]
