Actually, -X:ExceptionDetail is the more important option. Could you try that?
It will you the System.Exception stack trace.
Hmmm... still not sure it is more useful.

Michael, what is the CLR stack trace (-X:ShowClrExceptions)?
Not much more useful I'm afraid.

Adding Luke Hoban, the F# ninja at Microsoft =)
Luke, any ideas? Swing by my office if you are confused.

Subject: [IronPython] Viewlets: Any F# experts here?
The viewlets that come with VSLab look *really* cool. They're based on
F# so I decided to see if they could be used from IronPython.
http://www.codeplex.com/vslab
The dependencies are pretty hefty. You need F# installed *and* Managed
DirectX (June 2008 SDK ~450mb seems to fulfil the dependency).
To get at the viewlet assemblies you need Visual Studio Pro installed
as
well, but they can be extracted from the VSLabs msi installer without
VS
Pro.
Ok, so with all the dependencies installed I attempt to use them - and
*boom*. Anyone here got any ideas?

Interesting that the explosion is inside winforms. Referencing that
assembly first makes knows difference.
