The  Process class in  System.Diagnostics allows you to launch a new process.

For security reasons, the  Process class is not available in the

Metro profile, and you cannot start arbitrary processes. Instead,

you must use the  Windows.System.Launcher class to “launch” a

URI or file to which you have access, e.g.:

Launcher.LaunchUriAsync (new Uri ("http://albahari.com"));

var file = await KnownFolders.DocumentsLibrary.GetFileAsync ("foo.txt");

Launcher.LaunchFileAsync (file);

This opens the URI or file, using whatever program is associated

with the URI scheme or file extension. Your program must be

in the foreground for this to work.

The static  Process.Start method has a number of overloads; the simplest accepts a

simple filename with optional arguments:

Process.Start ("notepad.exe");

Process.Start ("notepad.exe", "e:\\file.txt");

You can also specify just a filename, and the registered program for its extension

will be launched:

Process.Start ("e:\\file.txt");
