10/24/2023, 2:10 PMHey Im currently stuck on a problem which is driving me crazy :/. I tried to upgrade my Umbraco from 12.0.1 to 12.2. Everything went correctly but when the new Umbraco started an error popped up which said that there is "no database provider". The Umbraco Backoffice is still working but my custom database which i added in the startup.cs via "services.addUmbracoEfCoreContext" does not work. I dont know why. Could the problem be because of the EntityFramework Version?

10/25/2023, 12:09 PMYea you can but you'd have to change how you're calling the UseSqlServer

options.UseSqlServer(connectionString, builder =>
{
builder.MigrationsAssembly(typeof(SomethingInYourMigrationAssembly).Assembly.GetName().FullName);
});u

10/25/2023, 12:16 PMhmm I see. Thank you very much for that input. I generated a test migration via "dotnet ef" and it seems to be working fine. The only "problem" that occurs is that dotnet ef can find more than one DbContext but with "--context" it fixes the problem.
