Question

I am trying to restart an application in WPF.

I tried the following:

Process.Start(Application.ExecutablePath);
Process.GetCurrentProcess().Kill();

And it doesn’t work because the application is setup as a single instances application.

Then I tired this:

Process.GetCurrentProcess().Kill();
Process.Start(Application.ExecutablePath);

And it doesn’t work because once we Kill the process it will not hit line 2

Is there a way to schedule a the .Start so that I don’t run into issue #1.

Answer 1

You could launch a secondary application that would then re-launch your main program after the delay. When I wrote a self-updater a few years ago, that was the implementation path that I took. It was just a simple program that took the executable as a command line arg, would sleep for a tenth of a second, then .Start it.

A better implementation path than I took would be to have the newly-launched program wait for the process that launched it to terminate. Waiting the arbitrary length of time could complicate matters. In order to accomplish this, I would probably pass the process ID to the re-launcher so that it would know exactly which process to wait on.
