Background: I get a lot of traffic looking for details on running a process and collecting the process output. If you haven’t already done so, you should read “How to use System.Diagnostics.Process correctly“. It outlines the major pitfalls of using this class. Another post on “Using the ProcessRunner class” will demonstrate using the helper class [...]

The problem is that hard-coding the full path to the exe isn’t always the best option. This is why there is [...]

On occasion I would get fancy in one project or another and build something sorta-generic; however, every time it came to creating the next command-line tool I started from scratch. Finally I said [...]
