Calling back into the default expression evaluator doesn't work with arrays about concordextensibilitysamples HOT 1 OPEN

After poking at this some more, I think VS2019 shows the same behavior. I'm not sure why it appeared to be working previously. Probably something with the extension not being updated/replaced properly.

When I have an array variable the root visualized expression name is L"[0]" and the full name is L"()[0],nd". I use the full name to create a language expression and hand that to EvaluateExpressionCallback. Obviously, it doesn't know what do with that expression.

It's only the display string on the root that is messed up. When I expand it the root visualized expression full name is L"avDefault[0]" as expected. Though it does mean that the name shows up funny in the Watch window.

I see a similar issue if I have a pointer value and I use ,1 to tell the Watch window it's an array. Name and full name are both L"" when expanding the root object.

Note that the VSIX project may not load. I added the Microsoft.VSSDK.BuildTools nuget package and added Microsoft.VsSDK.targets as a build customization. When redistributing the project (without the nuget package directory) the project won't load because the targets file is missing. The targets file can't be downloaded unless you can load the project and let nuget re-download packages. Fun chicken and egg problem.
