I found a nice C# coding best practices doc from DotNetSpider today: http://www.dotnetspider.com/tutorials/BestPractices.aspx
Great to use as a starting point for your own standards.
A couple things I’d change:
1. There should only be 1 exit point in a method. The word return should only appear once, and it should be the last line in the method.
2. The Public regions should appear before Private regions in a class. When navigating to a business method from a UI class it seems more natural to jump into the top of a file and work your way down.
