- Adds `LanguagePrimitives.IsNullLike()` method to account for `DBNull.Value` and `NullString.Value` so that they can be considered the same as a null value where sensible in PowerShell.
- Updates `-ne` and `-eq` binders to treat `DBNull.Value` and `NullString.Value` as equal to null/AutomationNull.
- Update code paths for comparing objects in LanguagePrimitives to ensure consistency with how the `-eq` and `-ne` binders work when calling LanguagePrimitives methods to do the comparisons.
- Make `LanguagePrimitives.IsNull()` and `LanguagePrimitives.IsNullLike()` public methods.
- Added tests for null behaviours in `NullRepresentatives.Tests.ps1`
PowerShell serialization has a list of known PowerShell types. When an object is deserialized containing a known type it tries to deserialize the object to that specific type and throws an exception if it can't succeed. SemanticVersion only exists in PSCore6 so when remoting from Windows PowerShell or importing clixml generated from PSCore6 that contains SemanticVersion, it fails.
With this fix, it will be rehydrated as a "PSObject" with "Deseriealized.System.Management.Automation.SemanticVersion" in the 'TypeNames' in both Windows PowerShell and PowerShell Core.
Convert ShouldBeErrorId to Should -Throw -ErrorId in PowerShell tests.
Get rid of try { } catch { } formula to assert that errors were thrown.
Small fixes in tests to obey the new Pester -Parameter syntax.
Based on standard practices, we need to have a copyright and license notice at the top of each source file. Removed existing copyrights and updated/added copyright notices for .h, .cpp, .cs, .ps1, and .psm1 files.
Updated module manifests for consistency to have Author = "PowerShell" and Company = "Microsoft Corporation". Removed multiple line breaks.
Separate PR coming to update contribution document for new source files: #6140
Manually reviewed each change.
Fix#6073
1. The individual test files (.ps1) in `/test/powershell/engine` are moved to the corresponding subfolders.
2. The test asset file `test/powershell/Common/TestTypeFile.ps1xml` is moved to `test/powershell/Common/engine/Api/assets/` so that it's next to the test that is using the file.
