.Net Core support (again)

[MathiasMagnus]

Hi!

I revisited your module, to pimp up my own Import-VisualCommandPrompt module with VS15 support. (Once I'm done, I'll put it in a public repo.) However, your scripts fail to launch inside PS Core for some reason.

PS C:\Users\Matty\Source\Repos> $PSVersionTable

I tried tracking down the issue, but couldn't. The namespaces and the types it complains about exist in PS Core.

PS C:\Users\Matty\Source\Repos\msvs-com-helper> [System.Text.RegularExpressions.Regex]

IsPublic IsSerial Name                                     BaseType
-------- -------- ----                                     --------
True     False    Regex                                    System.Object

The docs say this type lives in the namespace it should. Also, my shell is running Core CLR, so this type should exist (even from C# I guess).

PS C:\Users\Matty\Source\Repos\msvs-com-helper> $IsCoreCLR
True

Any ideas what is the problem? Should you want to test, grab an installer or zip file from Powershell releases. Needs no install, just unpack and run powershell.exe.

@MathiasMagnus hi, sorry I missed your posting till now. As you might have noticed the modules gravitated towards wrapping vswhere.
If there is still interest, comment and I'll dig into the Regex issue.
