PowerShell -MatchOption default should be EqualsCaseInsensitive

[ThomasNieto]

Brief description of your issue

PowerShell is a case insensitive language, matching by case is opt-in. The MatchOption parameter default should be EqualsCaseInsensitive to have the standard PowerShell experience.

Steps to reproduce

Find-WinGetPackage -Id microsoft.powershell

Expected behavior

Only the matching Id is returned.

Find-WinGetPackage -Id microsoft.powershell

Name               Id                           Version Source
----               --                           ------- ------
PowerShell         Microsoft.PowerShell         7.4.4.0 winget

Actual behavior

The preview package is also being returned which should not happen unless PowerShell wildcards are used to do a like comparison instead of equals.

Find-WinGetPackage -Id microsoft.powershell

Name               Id                           Version Source
----               --                           ------- ------
PowerShell         Microsoft.PowerShell         7.4.4.0 winget
PowerShell Preview Microsoft.PowerShell.Preview 7.5.0.3 winget

Environment

Name                    Version
----                    -------
Microsoft.WinGet.Client 1.8.1911

The default behavior is to use a Substring search, which matches the WinGet CLI

@ThomasNieto, thanks for creating the issue. I'm still learning the PowerShell way and wouldn't have been likely to catch that once since I'm so used to the CLI experience. We should look to pass the right parameters via PowerShell to the COM API so the PowerShell experience matches the expectations here.

[ThomasNieto]

While testing some more it would be ideal to use the PowerShell way and use PowerShell wildcards. Right now even with the proposed setting it still returns other results other than the case insensitive match.

There is a class called WildcardPattern that you can use to ensure the match to the PowerShell way.
