Writing C# code is very easy now days. Having few months of experience and you can write a code, which compiles and runs. But developing a good application is not all about writing a code, which compiles and runs. Writing an efficient code or what we call "Production Quality" code requires having some coding standards in place.
These are the two C# coding standards which I liked. I am not saying everyone should use this but can have a look before making C# coding standards for their applications.
