Issues with migration EF Core + ASP Identity + IdentityServer4 - asp.net-core

Question

Trying to implement the IdentityServer 4 with Asp Core Identity and EF Core.
This tutorial to be precise (done every other before it as required): AspIdentity with EF Core
Everything is great until i have to run the migrations, which throws error:
An error occurred while calling method 'BuildWebHost' on class 'Program'. Continuing without the application service provider. Error: Invalid object name 'Clients'.
No DbContext named 'ConfigurationDbContext' was found.

}
context.SaveChanges();
}
}
}
}
NOTE: I started brand new project in ASP Core 2 framework so no migration from 1.x to 2.0 was needed.
What am i doing wrong?

Answer 1

To run an Entity Framework migration you need to disable the InitialiseDatabase call.
Once the migration has been created you can enable it again.

Answer 2

I know it's not your answer but if anyone else runs into this I found another cause. I was adding the ConfigurationDbContext to the DI container before adding it to IdentityServer and that caused the migration to not get added via IdentityServer.
Startup:
var migrationsAssembly = typeof(Startup).GetTypeInfo().Assembly.GetName().Name;
var optionsContextBuilder = new Action<DbContextOptionsBuilder>(options => options.UseSqlServer(authConnectionString, sql => sql.MigrationsAssembly(migrationsAssembly)));
// This caused my migration to not get run
services.AddDbContext<ConfigurationDbContext>(options => options.UseSqlServer(authConnectionString));
services.AddSingleton(sp => new ConfigurationStoreOptions { ConfigureDbContext = optionsContextBuilder });
// The above two lines needed to be moved below these lines
identityServerBuilder
.AddSigningCredential(certificate)
.AddConfigurationStore(options => options.ConfigureDbContext = optionsContextBuilder)
.AddOperationalStore(options => options.ConfigureDbContext = optionsContextBuilder)
Hope this helps someone else!
