How low do you go?

Recently, a couple of incidents have made me think about .NET and programming in general. Sam wondered if there was a way to find out if an assemlby was already registered in the GAC. I knew that the Fusion API had something to do with it, but it was undocumented (and I was also looking at the wrong DLL; if I would've looked at mscorcfg.dll I would've ILDasm/Anakrino'ed the sucker). So I grabbed the output of "gacutil /l" and created a couple of classes to search through the list. While this did the job, Mattias showed the true way.

Another incident revolves around the VB .NET compatiability layer. Someone suggested using StrDup(), but Drew showed via ILDasm that using one of String's custom constructors was the way to go. Essentially, StrDup() is just a wrapper method with some extra code bloat to boot, so why not use the constuctor?

On the one hand, I love it that it's easy to figure out what is really going on in a method in .NET. Tools like ILDasm, Reflector, and Anakrino make it painless to discover the hidden behaviors of a method. At the same time, though, I find myself wondering, "aren't methods supposed to hide those details from us anyway?" The intent of Design-By-Contract (DBC) is desirable. To know what the method expects from me and what it will uphold when it's done without having to see the source code would make development time easier. In essence, I'd like to know the method's behaviour without having to see it. I just find it funny how OO development is supposed to encapsulate implementations and you end up needing ILDasm to figure out what the encapsulated behavior is!
