Pass parameter to function via reflection

I have an extesion method with the following signature

public static void AddConfiguration<TEntity>(this ModelBuilder builder, EntityTypeConfiguration<TEntity> configuration)
    where TEntity : class
{
    ...
}

I want to pass the parameter via Reflection and tried this method:

var ctors = type.GetConstructors(BindingFlags.Public);
modelBuilder.AddConfiguration(ctors[0].Invoke(new object[] { }));

And this way:

modelBuilder.AddConfiguration(Activator.CreateInstance(type));

Both return an object so the method does not accept them. Is there any way to do that?
