Steps to reproduce

Get-DscResource doesn't show class-based DSC resources if the PSD1 has all of these CmdletsToExport, FunctionsToExport, AliasesToExport. To mitigate the issues, one of them has to be commented.
This is a bug introduced during the PowerShell performance related changes. Andrew Menagarishvili has looked into the code and confirmed this bug.

Expected behavior

Get-DscResources should return DSC resources

Actual behavior

Get-DscResource doesn't show the DSC resource

Error details

No error.

Environment data

Observed with OpenSSH V7.1+.

Visuals

Get-DSCResource doesn't show the class-based DSC resource

With workaround by commenting functionsToExport, Get-DscResource shows the class-based DSC Resource

Possible temporary workarounds until the bug is fixed:

1. comment out any of CmdletsToExport / FunctionsToExport / AliasesToExport (for example, it it is an empty array)
2. specify a wildcard for any of CmdletsToExport / FunctionsToExport / AliasesToExport

I have just experiences the issue and it took some time to find out what it was caused by that bug. Are there plans to fix it?
