mutex

Using C# and WPF under .net (rather than WindowsForms or console), what is the correct way to create an application that can only be run as a single instance? I know it has something to do with some mythical thing called a mutex, rarely can I find someone that bothers to stop and explain what one of these are.

The code needs to also inform the already running instance that the user tried to start a second one, and maybe also pass any command line arguments if any existed.

In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More
