I've been reading a bit about immutable structures such as string. Simply put, they don't change state once they've been created (so for instance asking for a substring gives you a new string). Now, I was wondering whether the CLR "knows" that a certain type is immutable, and uses this fact to do something clever at runtime, or is immut...
I'm trying to make a .NET wrapper for an REPL (specifically Scheme, but I haven't got to where it matters).

In an Android app, I am looking for the functionality of the .NET string function [Trim('aaa')] which will trim off the text "aaa" off a string.

I'm working an a form with a progressbar, which is meant to have certain colors (foreground and background). On my XP machine, the colors are correct. On my Windows 7 machine, the form looks all sexified (just like all the other windows 7 windows) and the color is not what I had set in the designer. Is there some sort of style option th...
I don't know much about the CIL, except that there is metadata in assemblies that record the type information. Would it be possible to create some reflecting tool that is able to read a C# or VB.NET assembly and change its metadata so that all class members become public? Would it be straightforward (e.g. change one or two bytes for ea...
