Same problem in .NET 8.0.0-rc.1.

Same problem in .NET 8.0.0-rc.1.

I had the same problem.
I succeed to do it by using the .NET CLI instead of the Visual Studio. It seems it's when we define the DbContext. Without it, it works well.

Not working :
dotnet aspnet-codegenerator identity -dc OCuverie.Data.OCuverieAuthContext --files "Account.Register;Account.Login;Account.Logout"

Working :
dotnet aspnet-codegenerator identity --files "Account.Register;Account.Login;Account.Logout"

After commenting out app.MapRazorComponents(); in Program.cs, the scaffolding worked.

Did not work for me using "Blazor Web App" project template under .NET 8.0.0-rc.1.

Did not work for me using "Blazor Web App" project template under .NET 8.0.0-rc.1.

Also needed to comment out using .Components. You end up with razor pages and a directory structure that needs work. Probably not that useful in a Blazor app.

Hey,
I just merged a fix for this, will be available in 8.0.0-rc2.

Is there a work around while we are waiting for 8.0.0-rc2?
