How can I use IdentityServer 4 and SQL Server?

I followed http://docs.identityserver.io/en/latest/quickstarts/7_entity_framework.html#database-schema-changes-and-using-ef-migrations to use SQL Server with IdentityServer 4

Getting error while try creating Database, IdentityServer4

Microsoft.Data.SqlClient.SqlException (0x80131904): Cannot insert the value NULL into column 'Id', table 'is4aspiddb.dbo.AspNetUserClaims'; column does not allow nulls. UPDATE fails.
