I have a static object at runtime that is basically a list of other objects (ints, strings, Dictionary, other objects, etc). Is there way to determine the memory used by my static "list of other objects" object at runtime? This would be handy for instrumentation and reporting purposes. ...

C# .NET 3.5. I'm trying to understand the intrinsic limitation of the C# Action object. Within the lamda (are those, in fact, lamdas?), we can perform assignments, call functions, even execute a ternary operation, but we can't execute a multi-statement operation. Is this because the single-statement execution is just syntactic sugar f...
I remember reading a post about a year or so ago by Scott Hanselman (maybe by scott guthrie) about how Linq evolved. It remember it showing that anyonymous types led to lambda expressions which then led to Linq in some way. I can't seem to find it on google. Does anyone else remember this post?
