            Bug ID: 52852
           Summary: Retrieving all properties from wmi class with
                    "Select-object *" fails (in powershell core)
           Product: Wine
           Version: 7.6
          Hardware: x86-64
               URL: https://github.com/PowerShell/PowerShell/releases/down
                    load/v7.0.3/PowerShell-7.0.3-win-x64.msi
                OS: Linux
            Status: NEW
          Keywords: dotnet, download
          Severity: normal
          Priority: P2
         Component: wmi&wbemprox

(prerequisite: winetricks -q dotnet48)

The following code retrieves all properties from a class in PS Core on Windows
(tested with a few common classes):

([wmiclass]'\\.\root\cimv2:win32_logicaldisk').GetInstances() |Select-Object *

In all classes in wine I get:

"format-default: Error code: 0x80041002"

With the hack at the end of this post it works in wine too for most classes, so
maybe it might be easy to fix (?). Returning anything else then an error that
starts with 0x8* works really I found by trial and error.

However the hack also doesn`t work (breaks) cases like win32_process where the
count is more then one, so I guess the fix might be more complicated after all:

([wmiclass]'\\.\root\cimv2:win32_process').GetInstances() |Select-Object *

Output (with hack):

Select-Object: Z:\home\louis\ramdisk\a.ps1:1
Line |
   1 |  … class]'\\.\root\cimv2:win32_process').GetInstances() |Select-Object *
     |                                                          ~~~~~~

     | The following exception occurred while retrieving members:
     | "Object reference not set to an instance of an object."


Steps to reproduce:

-   winetricks -q dotnet48
-   Install PS Core from downloadlink.
-   Save the following line in a file called for example a.ps1:

([wmiclass]'\\.\root\cimv2:win32_logicaldisk').GetInstances() |Select-Object *

-   Then: 'wine pwsh -file a.ps1'


Hack:
