What is the quickest way to find out which .net framework linq methods (e.g .IEnumerable linq methods) are implemented using deferred execution vs. which are not implemented using deferred execution. While coding many times, I wonder if this one will be executed right way. The only way to find out is go to MSDN documentation to make su...

I've created a class named Room and I am using a PropertyGrid to allow users to see and edit the properties of the Room instances. A few properties are restricted to a set of standard values.
