We’ve seen an issues with projects created using the Blazor Tailwind template due to it still referencing the ServiceStack MyGet package sources in the template itself.
Recent changes to ServiceStack.Blazor currently deployed in MyGet will interfere with code existing in the template. The fix is to delete the NuGet.Config file in the base directory and not reference the ServiceStack MyGet from your machine wide config.
The template has been updated to resolve this issue, so newly created projects won’t have this problem. If you experience any other build issues with this template, let us know.
