Exception after fresh install of VirtualDesktop 1.18

[neilkatin]

I tried running VirtualDesktop 1.18 today (downloaded from the github release folder). I get this error when I run it:

Downloads/VirtualDesktop11 /list

Unhandled Exception: System.TypeInitializationException: The type initializer for 'VirtualDesktop.DesktopManager' threw an exception. ---> System.InvalidCastException: Specified cast is not valid.
   at VirtualDesktop.IServiceProvider10.QueryService(Guid& service, Guid& riid)
   at VirtualDesktop.DesktopManager..cctor()
   --- End of inner exception stack trace ---
   at VDeskTool.Program.Main(String[] args)

I tried both VirtualDesktop11 and VirtualDesktop11-24H2 (I don't think I'm running the win11-24h2 patch, but I wanted to see if it made a difference).

I apologize in advance if this is a RTFM issue.

Just for background info: PSVirtualDesktop also didn't work, so there may be an issue with my machine relative to VirtualDesktop assumptions.

Hello @neilkatin,

sorry this does not work. Can you please post the Windows version you're using (as seen with Winver.exe) and the Powershell version (just execute $PSVersionTable and post the PSVersion).

Greetings

Hi Markus.

Windows 11, V21H2 OS Build 22000.2538

Powershell 7.4.3

[FuPeiJiang]

I could reproduce this issue and get the same error message on: 22000.2538,

the IID for this version should be: b2f925b9-5a0f-4d2e-9f4d-2b1507593c10

VirtualDesktop21H2.cs would work
https://github.com/MScholtes/VirtualDesktop/releases/download/V1.16/VirtualDesktop11-21H2.exe
https://github.com/MScholtes/VirtualDesktop/releases/tag/V1.16

I did: git grep b2f925b9-5a0f-4d2e-9f4d-2b1507593c10 $(git rev-list --all)

refer to https://github.com/FuPeiJiang/Windows-BuildNumber-VirtualDesktop/blob/main/byVersion.txt for which IID and which
method indexes are used for each windows build version range

the README.md offers a more simplified view: https://github.com/FuPeiJiang/Windows-BuildNumber-VirtualDesktop/blob/main/README.md

since the binary VirtualDesktop11.exe is only 65kb, you could do an all-in-one version using if statements and it'd still be small

VirtualDesktop-All.exe ?

Hello @neilkatin,

I apologise for the late reply, I was on holiday.

Windows 11 21H2 is out of support (https://learn.microsoft.com/en-gb/lifecycle/announcements/windows-11-21h2-end-of-servicing), so I removed the code for this version from VirtualDesktop. Please update.

@FuPeiJiang: I make an all-in-one-version in the compagion repository PSVirtualDesktop (https://github.com/MScholtes/PSVirtualDesktop), it is much more effort to maintain.

Greetings

First of all: no need at all to apologize for having a life apart from this project; I appreciate
you making it available at all.

Unfortunately my machine running win11 21h1 died, I spun up a new machine running 23h2 and the 1.18 release works fine, as you expected.

I assume that the issue no longer exists as there is no feedback.
