Sorry for what is probably a silly question but it's bugging me... int[] i = {3, 2, 1}; //why Array.Sort(i); //instead of i.Sort(); char c = 'c'; //why char.IsLetter(c); //instead of c.Isletter(); ...

What are the main advantages of switching to DLR for my scripting language?
I have written a DSL using Antlr to generate a lexer and parser from my grammar file.

How does the Entity Framework tell whether a multiplicity of "one" or "zero or one" should be used on a relationship?
I'm programmatically creating an edmx file as part of our code generation process and I'd like to know how the designer decides to use "1" or "0..1" for a relationship when you "Update model from database". Any insight on this? Thanks Edit: Ok, I think it uses "0..1" when the "many" side is a nullable foreign key and "1" if it's not nu...
