A bit of quality time with Reflector shows that there's a

need to call VSLabFSICore.Viewlets.Init() first. It's static, and in

Thanks Curt - your reflector-fu is greater than mine. I should spend
some quality time with it.
Your advice gets me to the next step, I can make a GraphControl flash
momentarily into view (on creation), but attempting to show it causes
another explosion:

The code that produces this is:
import clr
clr.AddReference('vslabfsicore')
clr.AddReference('vslabviewlets')
from VSLabFSICore import Viewlets
from GraphViewlet import GraphControl
Viewlets.Init()
g = GraphControl()
g.Show()
If instead of 'g.Show()' I attempt 'dir(g)' I get a very odd error!

Incidentally, even when installed with VS Pro I can't get VSLab to work
*anyway* (this is Vista 64bit FWIW), so the code may not be ready for
prime time.
I may try firing up reflector myself and see where it takes me.

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.

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.
