"No DbContext named 'ConfigurationDbContext' was found" error

[Tony20221]

The instructions says to run these from Migrator folder
dotnet ef migrations add Init --context AdsDbContext -o Migrations/AdsDb
dotnet ef migrations add Init --context ConfigurationDbContext -o Migrations/ConfigurationDb
dotnet ef migrations add Init --context PersistedGrantDbContext -o Migrations/PersistedGrantDb

The last two gives errors:
No DbContext named 'ConfigurationDbContext' was found.
No DbContext named 'PersistedGrantDbContext' was found.

And the first one while it didn't give any errors, it didn't create any tables in the database.

Close this as IdentityServers were moved to a separate folder /src/IdentityServer
