 Why create yet another coding standard document?

There have been numerous attempts to document C# Coding Standards since the language was released, but most are either overly verbose, too restrictive, or try to cover every single scenario.  This is my attempt to start from scratch and write a new standards document that is concise, simple to read & use, and creates a pragmatic balance of rule enforcement.  Having said that, I'm sure that many of you will have just as many disagreements with this document as I have with others, but I am always up for a good debate. :)

Goals and objectives:

  • Cover all major C# Language features.
  • Provide guidelines on coding style & language usage (but not syntax)
  • Demonstrate all rules in code where applicable.
  • Describe rules in structure that is easy to read & use.
  • Define clear & concise rules.
  • Use consistent terminology & rule patterns.
  • Only provide rules where there is a clear cut best practice.
  • Lead developers to a "pit of success" and avoid common "pits of failure"
