- Fix PSScriptAnalyzer warnings of type PSAvoidUsingCmdletAliases for 'ForEach-Object' (alias is '%' or 'foreach') - Fix PSScriptAnalyzer warnings of type PSAvoidUsingCmdletAliases for 'Where-Object' (alias is '?' or 'where') - Fix PSScriptAnalyzer warnings of type PSAvoidUsingCmdletAliases for 'Select-Object' (alias is 'select') - Fix PSScriptAnalyzer warnings of type PSPossibleIncorrectComparisonWithNull. Essentially, $null has to be on the left-hand side when using it for comparison. - A Test in ParameterBinding.Tests.ps1 needed adapting as this test used to rely on the wrong null comparison - Replace a subset of tests of kind '($object -eq $null) | Should Be $true' with '$object | Should Be $null'
