Am I missing something in the build?
could you share which repo and project that you are trying to run? Skclusive.Samples?
Yes, Skclusive.Blazor.Samples repo. I see that the Dashboard.Browser.Host project is set as the startup project.
could you try the same in dotnet cli? i do not have windows machine to reproduce the issue.
