C# getting optional parameters
By Arthur Correa • Author
Scott Guthrie just posted about a few new features in C# 4.0. Optional parameters are now part of the language. These are something that I've missed since I made the switch to C# from C++ back in 2001 (Dont' get me wrong, it wasn't the end of the world, its easy enough to work around when you dont' have them, but its nice to have them back).
He also shows an example of how you could use them with ASP.Net MVC. All in all, like usual, he has some good info so check it out.
