When Group-Object is used with the switch AsHashTable and Property
specified as a string expression then the result hashtable indexer
($table[key]) does not find expected entries.
Other expressions, i.e. not strings, may produce expected results.
Scripts
- Test-1.property.string.ps1 - expected results with a property name
- Test-2.expression.string.ps1 - unexpected results with the seemingly same string expression, fixed in v6.1.0-preview.4
- Test-3.expression.number.ps1 - expected results with a numeric expression
