What version of .NET are you using? i.e. what do you get if you enter dotnet --version at a command prompt?
I'm not seeing these errors after downloading a fresh zip of the repo, extracting and running run.bat

[xcom169]

I think I have multiple versions installed.
Maybe it's too fresh ? v5.0.203

[csinkers]

It won't be that then, mine's working with v5.0.203
The file path of the first file is odd: netstandard2.0.NETStandard,Version=v2.0.AssemblyAttributes.cs
There should be a \ in there after "netstandard2.0" (build\UAlbion.Api\obj\Debug should only contain a netstandard2.0 directory, no files).

None of that looks like it should be causing a problem, if I download a fresh copy it works and github action builds are working on windows, linux and mac so it must be some weird environmental thing. Some things to try:

• cloning it with git rather than downloading the zip
• building with Visual Studio rather than run.bat / the dotnet cmdline utility (Community Edition or VS Code should both work)
• if those don't work, try compiling using dotnet with full verbosity and I can take a look (upload the results to https://gist.github.com/ or something and link to it, it'll be too long for a comment). Running dotnet run --project src\ualbion -v diag >build.log should compile and write everything to "build.log".
