If it is just about your connection-string (is it?), you may want to check this answer, which basically suggests this code in your startup-project (not in your migrations-project):

var myConnectionString = Configuration.GetConnectionString(myConnectionStringName);
services.AddDbContext(options => options.UseSqlServer(
    myConnectionString ,
    x => x.MigrationsAssembly(myDbContextAssemblyName)));
