How do I run PowerShell scripts in debug mode in PowerGUI under .NET 4 Framework?

Question

I've read the whole thread about running PowerShell under .NET 4.0, including the warnings about what happens when using the registry keys to make the scripts run under that framework.

So far, I only get the desired result with the registry keys. Is anyone aware of a way to make this work without changing the registry keys? When I checked PowerGUI's discussion boards, even they pointed to the stackoverflow thread. Has anyone come up with something better since April 2010?

1- Go to: "C:\Program Files (x86)\PowerGUI" and create a "ScriptEditor.exe.config" file.

2- Paste this xml in the file

<?xml version="1.0"?> 
<configuration> 
    <startup useLegacyV2RuntimeActivationPolicy="true"> 
        <supportedRuntime version="v4.0.30319"/> 
        <supportedRuntime version="v2.0.50727"/> 
    </startup> 
</configuration>

3- Enjoy

This way, your change won't alter the whole machine.

RE "something better" - short of PowerGUI being recompiled to target .NET 4.0 - no. Out of curiousity, what .NET 4.0 feature are you trying to access in .NET 4?

Oh, bignum support would be quite nice to have natively. Some Project Euler tasks are awkward to do otherwise. – Joey Jul 14 '10 at 22:25
We have some custom cmdlets we're using for UI automation that are compiled under .NET 4. – Scott Lawrence Jul 15 '10 at 14:11

I'm not a dev but maybe you create a config file for powergui. Check this page:

The config file only applies for PowerShell ISE. I've already made that configuration file change. – Scott Lawrence Jul 15 '10 at 14:09
