I am trying to build an app from a simple server hosted web assembly (https://github.com/MarkStega/BlazorApp1). I have not yet been able to reproduce the issue. I will keep adding content from the failing project until I can reproduce…

@TanayParikh We have a similar report on EF Core (https://github.com/dotnet/efcore/issues/29491) that has regressed our Migration Bundles feature in 7.0. The bundle is a separate project that references the Blazor app. It fails when calling dotnet publish on the bundle project.
