I'm attempting to use Unity for the first time and I think I might have bitten off more than I can chew. We have a n-tier application that has a base library with several abstract types and then several business scenario specific libraries on top of it w/ concrete types.

Hi, I'm wondering if there are any .NET libraries (ideally open-source) that deal with guitar chords (e.g. given either a chord or a set of fret/string combinations it can retrieve the corresponding fret/string combination or chord respectively). I'm having some trouble searching because "C#" is a note and there is a concept of "progra...

We have discovered that one of our auto generated assemblies is throwing a StackOverflowException on new(). This class has (bear with me please) 400+ simple properties that are initialised (most by default(string) etc) in a constructor. We notice that its fine on 64 bits but on 32 bits it goes bang! We need to test if it's reasonable ...
