macOS build with VS for Mac

[bruno-garcia]

Builds with dotnet CLI but fails with Visual Studio for Mac

I'm hitting this issue on macOS 10.13.6 with Visual Studio for Mac 7.7 preview (build 1282)

Mono version:

17:04 $ mono --version
Mono JIT compiler version 5.16.0.151 (2018-06/5e81afa90df Fri Sep  7 12:05:47 EDT 2018)

Seems related to dotnet/Nerdbank.GitVersioning#224

[tmat]

Do you use both SourceLink and Nerdbank.GitVersioning in your project?

[bruno-garcia]

@tmat I use only:

<PackageReference Include="Microsoft.SourceLink.GitHub" Version="1.0.0-beta-63127-02" PrivateAssets="All" />

I think both at the end use libgit2sharp

[bording]

In both issues, the problem is coming from when things are being run from Mono, but the stack traces are showing that it's coming from different parts of LibGit2Sharp.

I wish there was a way to tell which method was causing the problem here.

[tmat]

This seems like the native library is failing to load. The stack trace is the same as if I delete the library.

Let's track all Mono issues here: #155
