>>However if value is changed it's only 'definitions' class that you need a recompile (other classes obtain value at runtime despite compile time if it's a field and not a constant). Also with constants and fields you're not limited to simple types and could get the value using a method (and say read from a txt,xml file or ask to user etc). ie:

That is suggested by Bill Wagner as well in his excellent books "Effective C#" and "More Effective C#". In fact it is the second of 50 tips in the first book: "Prefer readonly to const".

Good books, BTW. The second one focuses on new features in C# 3.0 and 3.5. He is probably running like a hamster on a wheel on another volume, covering C# 4.0, even as we speak ;-)
