Are there any built-in mechanisms in .Net that would allow us to write two programs, A and B. A is a process with special hooks onto which B attaches itself. This would allow B to gather whatever information those hooks provided. In particular, it would be nice to be able to dial into another of our process and gather suchs metrics li...
