Can we get this merged soon? Turns out this is the reason every status query fails with the most recent dotnet runtime (5.0.7).

Thanks!

Hi @bording, I'm tagging you here, because you seem to be the member of libgit2 who most recently interacted with this repository. Quite a few people are affected by this issue here. Any chance you can release a new (preview) version after merging this PR?

Thanks
Stefan

Thank you so much, @bording. Now libgit2sharp is working again with the most recent dotnet runtime. Awesome!
