The repository is building a Linux arm/arm64 VM in WSL2 so you can play with .NET core debugging on arm/arm64 system as the below without buying a real hardware.

Two goals of the project:

1. Lower the gate to play .net core app on Linux arm/arm64.
2. Provide a "All-In-One" package and a "Full Stack" debugging experience in OSS world(from qemu,linux kernel,clang/llvm,lldb/gdb,sos,.net core app)

The target arm/arm64 VM contains:

• The linux system (6.0.x) - build by the buildroot gcc toolchain
• The gdb (12) - build by the buildroot gcc toolchain
• The lldb (15.0.x) - build by the buildroot gcc toolchain
• The SOS lldb plugin (main branch) - build by the clang/llvm(for native part) + MS compilers(for managed part)
• A selfcontained .NET core applciation with the .NET core runtime (.net core 6.0 or 7.0-dev) - build by the host clang/llvm(for native part) and MS compilers(for managed part))

Also have the following tools built for the host x86-64:

• The qemu (7.1.0) - build by the buildroot gcc toochain, which is used to host the arm/arm64 vm built.
• The latest clang/llvm (main branch) - build by buildroot gcc toolchain, which is used to cross compile the above SOS lldb plugin and the native part of the .NET core runtime for arm/arm64 target.

There are two ways to get the VM package to play:

1. build arm/arm64 VM (Linux + GDB + LLDB + SOS + .NET Core applcation) from scratch
   Building from scratch could take several hours or even longer, it depends on how powerful of the hardware is.
   or
2. You can donwload the released VM and use it directly

After build or download the VM package, you can

1. .net core app on arm64 vm debugging
2. .net core app on arm vm debugging
3. publish a .net core app to vm for debugging
4. host qemu debugging
5. linux lernel debugging
6. lldb sos plugin debugging
