What are the alternatives to System.Diagnostics API for running external EXE or BAT files under IIS hosted web application? I would like to run external EXE program from my ASP.NET-MVC web application. I don't need to wait till the program exits. I just want to start the program. The execution can take some time or it may crash, so I would like to run it separatelly from IIS in such a way that the web application only triggers its execution.
