That "dir" error is a known problem with beta 3 -- and as you
might imagine, sky-high in priority on our list of things to fix
for beta 4.
Viewlets appear to be user controls; you probably need to host one
in a Form.

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

It's static, and in the vslabfsicore module.
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.
