Dotnet webapi doesn't compile on fedora 32 podman

Note: All works fine outside of podman, as you can see here:

[dell@localhost webApi]$ cd Podman/test/
[dell@localhost test]$ dotnet build

# Dotnet webapi doesn't compile on fedora 32 podman

When I just try to compile a webapi project created from CLI, i'm getting this message:
> /usr/lib64/dotnet/sdk/3.1.108/NuGet.targets(123,5): error : '32 (Container Image)' is not a valid version string. (Parameter 'value') [/home/dell/Escritorio/webApi/Podman/test/test.csproj]

Be as descriptive as you can with your title.

With my Fedora .NET Core package maintainer hat on, the bug is not in podman. It probably can be worked around in toolbox. But the real culprit is .NET Core/msbuild, as I say in the linked .NET Core issue.

Thanks for opening and the issue! Based on the last comment, I will close the issue as it appears to be unrelated to Podman.
