NuGet package version 3-beta-1, 2.0.1

Runtime version .net core 2.2 and 3.1

Additional context Perhaps it is related to the IncludeRazorContentInPack variable in the build pipeline.

I’ve been digging around without finding any answer to this. Maybe it will be solved if we move to Razor pages? I can see that the package Microsoft.AspNetCore.Identity.UI uses Razor class library with the same convention as us, but they do Razor pages instead of Controllers. Maybe that will solve it? We do consider moving to Razor pages as part of the refactoring that will be done in 4.0.0.

Microsoft.AspNetCore.Identity.UI does some scary magic things with the build pipeline in their csproj file, but I don’t think that will solve it either. Looks like stuff to handle booth bootstrap 3 and bootstrap 4.

This seems to be solved now. Let me know if you disagree @span 😃
