Description

I'm making a VSIX extension that does Git operations, I ran into this issue while trying to get the corresponding repo for the active document. When testing in the LLVM repo, doing Repository.Discover() on the active file C:\Users\<my_user_name>\source\repos\llvm-project\clang\lib\Format\UnwrappedLineParser.cpp throws in Release mode, but on Debug mode it correctly gets the repository path of C:\Users\<my_user_name>\source\repos\llvm-project\.git\

Reproduction steps
  • Create Visual Studio Extension project and add a command, set build to Release mode
  • Within the command, get active document with DTE applicationObject = (DTE)await AsyncServiceProvider.GlobalProvider.GetServiceAsync(typeof(SDTE));
  • Get full file path with var filePath = applicationObject.ActiveDocument.FullName
  • Call var repoPath = Repository.Discover(filePath)
Expected behavior

repoPath holds the path of the repository

Actual behavior

Exception is thrown with the message The type initializer for 'LibGit2Sharp.Core.NativeMethods' threw an exception.

Version of LibGit2Sharp (release number or SHA1)

0.30.0

Operating system(s) tested; .NET runtime tested

Windows 11, .NET Framework 4.8

Research direction

Start by reproducing the Release-mode failure from the Visual Studio extension command, using Repository.Discover(filePath) with the active LLVM source file. Inspect the NativeMethods type initializer and compare the Release and Debug behavior on Windows 11 with .NET Framework 4.8. Done means Repository.Discover returns the repository path in the Release build without throwing.
