IndexOutOfRangeException in WpfFactories

[psfinaki]

I keep occasionally getting this exception when opening VisualFSharp solution:

System.IndexOutOfRangeException: Index was outside the bounds of the array.

I don't have a proper repro yet. A few thoughts and observations:

1. This generally doesn't seem to have any catastrophic influence on the repo behavior
2. I feel this is happening only when opening the solution after the fresh build using build.cmd
3. I feel this might be related to the colorization issues in VS, it takes very long to get my colors in VS
4. I couldn't get into the error when trying to debug things using VisualFSharpDebug

I might look closer into that, for now just poking around if anyone has ideas or has also seen this.

#17602 ?
building vsix from main (9rc1) should fix it, I think.

However, I too did notice the IDE is unusually sluggish recently.

Right, that might be related. Let's probably wait with this then :)

Not related, and not our issue. If happens in latest main, please report to wpf
