While “industry practices” are hard to discuss in an industry that has yet to even ship its first release, Microsoft has released some guidelines to its own naming conventions, used predominantly in the Framework Class Library; even if you and your development shop choose to use alternative conventions, understanding the naming conventions of the FCL is key to using it effectively.

There are three elements of naming guidelines:

  • Case (capitalization)
