Unable to resolve service for type

Radzen Studio Angular
1

I have create new Application "Test4"
Infer Database worked, pages were generated.

But when I try to start "Test4" I get error message saying that "Test3....." can not be found
Why my Application "Test4" want to access "Test3" code ?

dotnet: fail: Microsoft.AspNetCore.Diagnostics.DeveloperExceptionPageMiddleware[0]
An unhandled exception has occurred while executing the request
System.InvalidOperationException: Unable to resolve service for type 'Test3.Data.Test3Context' while attempting to activate 'Test3.Controllers.Test3.ArtikelstammsController'.

App starts but I can not read or write data, I get error "Unable to create new record"

Did you create the application in the same directory as Test3? If this is the case delete the server and client directories (only leave meta). It looks that the old code from the Test3 application still remains. Radzen will not delete any existing code.

I deleted server and client directories now it works
