Why does Mutex instantiation throw System.IO.DirectoryNotFoundException when I use a path for the name parameter?

When I do this:

using (Mutex MyMutex = new Mutex(true, Environment.CurrentDirectory))
{

}

A System.IO.DirectoryNotFoundException is thrown. I see other questions on here addressing how to avoid that which is to replace \ with something else like . or -, but I want to know why it's doing that. Why is it try to resolve the mutex name as a path? It doesn't try to resolve asdf as a path. What is going on here?

The Mutex is created within a store called the ObjectDirectory, all Mutex keys are actually paths within this store. The fact that you've given an absolute path, means the implementation will try to resolve that. Take a read of the win32 document here
