Please Sir May I Have a Linker?

Joel Spolski: "For some reason, Microsoft's brilliant and cutting-edge .NET development environment left out one crucial tool... a tool that has been common in software development environments since, oh, about 1950, and taken so much for granted that it's incredibly strange that nobody noticed that .NET doesn't really have one.

The tool in question? A linker. Here's what a linker does. It combines the compiled version of your program with the compiled versions of all the library functions that your program uses. Then, it removes any library functions that your program does not use. Finally, it produces a single executable binary program which people can run on their computers."
