"IEnumerable Visualizer" support for our language

[RobertvanderHulst]

@sae42 Simon THANK YOU. You're the best!
This works indeed.
For those of you that are reading along:

[$RootKey$\AD7Metrics\ExpressionEvaluator\{GuidLanguage}\{GuidVendor}]
"ClrCustomVisualizerVSHost"="{E82F32A8-074E-465A-86E5-D68A87284F61}"

It would be really nice if all these registry settings could be documented somewhere!
I found a lot of settings in for example VCSharp_EE_Registry.pkgdef, but we could really use some documentation about this.

What do get from the troubleshooting logs when you try to open the visualizer?

@gregg-miskelly I was not aware of these troubleshooting logs. I'll try this and report back what I find. Thanks for the tip!

@RobertvanderHulst After seeing this issue I noticed this visualizer also didn't work for our EE. It seems you should be able to get it working by adding an extra registry entry for your EE (it worked for me at least):
"ClrCustomVisualizerVSHost"="{E82F32A8-074E-465A-86E5-D68A87284F61}"

I couldn't find much documentation on this entry but searching for ClrCustomVisualizerVSHost turned up this similar issue #26

Now that this is working, I have an additional question:
Why is the IENumerable viewer showing columns for properties and fields that are marked with [DebuggerBrowsable(DebuggerBrowsableState.Never)]. That really does not make sense, and makes the display really ugly.
Or do I need to implement a DebuggerTypeProxy for these types?

I put out a PR to fix these in the Iris sample: #109
