In EntityFramework Core 8.
I’d like to change the default PK for UsersRoles table, currently set as follows:

table.PrimaryKey("PK_UsersRoles", x => new { x.UserId, x.RoleId });

to something else (e.g. including an additional column)

Is there a way to achieve the result using Migrations?

I can change table configuration using sql DDL but I don’t know if it is feasible to do it using migrations.
