Open a pdf with default windows behaviour from a WPF application

I want to open a PDF with the default windows behaviour the user has saved (e.g. internet explorer, adobe, whatever).

I found this solution Opening a .pdf file in windows form through a button click

and implemented it here:

        ProcessStartInfo startInfo = new ProcessStartInfo("MyPdfPath");
        Process.Start(startInfo);

Sadly I got an Error:

   System.ComponentModel.Win32Exception: "The specified executable is not a valid application for this OS platform."

I tried to google this error, but nothing of the first ten solution ideas worked.

The system is treating it like an executable, one way to get the document behavior is to set UseShellExecute to true:

ProcessStartInfo startInfo = new ProcessStartInfo("MyPdfPath");
startInfo.UseShellExecute = true;
Process.Start(startInfo);
