Error loading DLL git2-3f4182d on Windows (module not found)

[donk7413]

I'm developing a Visual Studio 2022 extension that uses LibGit2Sharp to retrieve Git repository information (such as the current branch name) and to manage open documents based on the active branch. However, when running my extension on Windows, I encounter the following error:

Unable to load DLL 'git2-3f4182d': The specified module could not be found. (Exception from HRESULT: 0x8007007E)

I noticed that the LibGit2Sharp.dll.config file only contains dllmap entries for Linux and macOS, with no mapping for Windows. Despite installing the LibGit2Sharp.NativeBinaries package and verifying that the project’s platform configuration (x86 vs x64) matches the deployed binaries, the error persists.

I'm running on .net 4.7.2. The code is pretty simple since it's an R&D POC.

string testDir = "";
try
{
    using (var repo = new Repository(_repoPath))
    {
        testDir = repo.Head?.FriendlyName;
    }
}

_repoPath is not empty, and it exists as the current Git repository. (with an .git folder)

Having the same problem any solutions?

Hey @donk7413 , I would like to inform you that it got solved when we downloaded that dll and put it under the "C:\Windows\System32" folder.

@cbarkinozer-softtech thanks for feedback, I will check it :)

I'm having this issue too. My application needs to run on multiple platforms so copying the dll is not a solution unless I package it and add platform specific code, is that the recommended approach and is there an example.

Thanks

I tried looking at the code to see where it loads libraries from and it looks inconsistent. When I compile, all the native libraries are copied into a lib directory, but LibGit2Sharp doesn't load anything from there. On Windows under .NET 8, it tries to load from win-x64\ directory in the bin directory.

Some documentation about how the directory structure for the native libraries should be organized would be nice. Currently, I have monitor my process to see. I'm not sure I'll be able do that on Linux/mac OS because my tool is Windows only.

Hopefully, I can ship all the native binaries together in my app because I can't create a unique version for each platform.
