Windows: Windows.Desktop v10.0.19043.1415
Package: Microsoft.DesktopAppInstaller v1.17.3411.0
Looks like I found the issue:
The import fails, because an error is thrown in Get-Version.ps1 in the line
$Result = [version](& "winget" $WinGetArgs).trimstart("v") .
The cast of winget --version into an object of type System.Version fails in case of a preview version (e.g. "1.2.3411-preview") as the constructor of System.Version does not accept a string of this format.
A string containing the major, minor, build, and revision numbers, where each number is delimited with a period character ('.'). MS Docs
As a consequence version "0.0.0.0" gets returned by the catch block and WinGet.Client reports a version mismatch.
Good catch! We've recently re-introduced "-preview" at the end of the versioning for preview versions.
This issue has been resolved with the latest version of the WinGet Client and the Microsoft.WinGet.Client module.
