What I have tried: I tried changing the name of the property, as well as the data type; nevertheless I got the same result. Additionally, I tried re-starting Visual Studio but once again, I got the same result.The issue now, is the even though the first method inside InitializeApplication (CreateRoles) is being executed normally, the second method does not seem to get executed (Break point didn't hit, and the expected database modification didn't happen).What I have tried:I tried changing the name of the property, as well as the data type; nevertheless I got the same result.

Add an implementation of IDesignTimeDbContextFactory[^]Looks like you’re trying to seed the data in the wrong place. You’re calling CreateModerator from your Configure method. That won’t work - the EF Core tools need to run that method in order to initialize the DbContext to discover what changes need to be added to the migration. Microsoft’s recommendation is to use the HasData method from OnModelCreating: Data Seeding - EF Core | Microsoft Docs[^] Alternatively, you could hook into the application lifetime, and seed the data when the application is started: asp.net core - Check conditions on startup - Stack Overflow[^] Personally, I prefer to have the migrations in a separate console application, with any seed data added there. I don’t like the idea of a web application connecting to SQL as a user with permissions to create and alter databases.Looks like you're trying to seed the data in the wrong place.
