Keep Your Azure Functions Up to Date: Identify Apps Running on Retired Versions

A couple comments:

The following line:

  $ver -notlike 'v7*' -and $ver -notlike 'v8*' 

should actually be:

  $ver -notlike 'v8*' -and $ver -notlike 'v9*' 

In addition, anywhere you see:

  'dotnet'

you might want it to be for both types.  I.e.:

{@('dotnet', 'dotne-isolated') -contains $_}

As well, I'm seeing the powershellversion value come back consistently as ''.  Is there a better way to get that information?
