I start VS2022 developer command prompt as administrator, and issue command "C:\Program Files\Git\bin\sh.exe" build.sh -configuration Release -platform x64 -target-framework net8.0 to build. Then I got following link errors:

Seems like it was caused by this commit: bbb0693
It is strange because its building fine on CI, it should be using this package for LLVM: https://github.com/mono/CppSharp/releases/download/CppSharp/llvm-6eb36a-windows-vs2022-x64-RelWithDebInfo.7z

But in your case its not finding the correct symbols.

Did you previously build CppSharp on this machine?

This is the first time to build CppCSharp on this machine. Actually, the correct LLVM package was downloaded:

C:\Users\CZhang6\Downloads\CppSharp-1.1.2\build>"C:\Program Files\Git\bin\sh.exe" build.sh -configuration Release -platform=X64 -target-framework net8.0
net8.0
Archive llvm-6eb36a-windows-vs2022-x64-RelWithDebInfo.7z already exists.
