well, C# is faster than VB.Net at least.
At doing what? Unless you've got unsafe code involved, I can't think
of
many things off-hand that you can't do exactly the same way in VB.NET,
resulting in virtual identical IL.
Try following code and Compare the results. Remember compare "remarked"
code also.
I would said C# is not a "superior" but "faster" language.
Sorry for ugly C# code, I'm not skillful in C#. (^^;)
