App layering 2206, missing citrix wmi classes.

Sergio Masone1709161115 · June 29, 2022

I dont know if this happened to anyone else, but i recently updated our ELM to 2206, and published a new image, so far ive had to strange issues,

1. one of my app layers had office runtimes installed which addded some folders in C:\Windows\Microsoft.NET\assembly\GAC_MSIL\Microsoft.VisualStudio.Tools.Office.Runtime.Internal, when publishing the image, the visual studio runtime shows as installed but the files from that layer are missing, it always was fine previous publishes..

2. all citrix WMI classes are not registered that come from the platform layer. the .mof files are all there, but the classes missing, have to manually register them.

I already have a ticket opened with citrix, but curious if others had something similar..

We have some similar issues after upgrading the ELM to 2206

If I check the old situation we had 591 folder showing up in C:\Windows\Microsoft.NET\assembly\GAC_MSIL

After the upgrade there are only 369 folders left in C:\Windows\Microsoft.NET\assembly\GAC_MSIL

Our SCOM Management Console and SCCM Agent wont run, It looks like same issue.

If I start the SCOM Manager it shows an error:

The exception message was: Could not load file or

assembly Microsoft.EnterpriseManagement.OperationsManager

And this folders/folders are also located in:

C:\Windows\Microsoft.NET\assembly\GAC_MSIL

We having same issue here.

Published different images and some seem not to have complete assemblies, which cause applications to be failing to launch on some images.

I thought the main thing in v2206 is migration of remaining menu items to Edge, with the discontinuation of IE.

It more than that has been done in this particular version

We got the same issue. Planning a rollback to 2204 right now und creating a ticket...

We had the issue here too. First noticed when Ms Visual Studio 2019 AppLayer not merged/composited correctly, This caused Vda registrations to fail as a missing entry in GAC_MSIL (Microsoft.VisualStudio.Diagnostics.ServiceModelSink) which is referenced in 'C:\Windows\Microsoft.NET\Framework64\v4.0.30319\Config\machine.config' caused the BrokerAgent to fail. Initially we implemented a workaround to remove <commonBehaviors><endpointBehaviors><Microsoft.VisualStudio.Diagnostics.ServiceModelSink.behavior/></endpointBehaviors> from the machine.config.

We have subsequently rolled back to 2204 without issue.

Out of curiosity, do you guys see this issue if you leave the OS layer on the old build tools? Wondering if it's the actual appliance upgrade or the OS tools (or both, I guess).

Bodo Borchers · July 11, 2022

Does your Layer Export work in 2206? It always tells me there is not enough space 0GB left. I think it is an issue with the appliance because the published machines in 2206 does not work with or without Machine OS Tools. Machine is full of errors and not registering to DDC.

Vincent Bernard · July 11, 2022

@Bodo. Saw issues with registration too, and ran this to determine GAC_MSIL was the cause --> Citrix Health Assistant - Troubleshoot VDA Registration and Session Launch. @Nick - Never tried that. Just rolled back Build tools, and appliance to 2204. Now a happy man after 40 hrs of troubleshooting multiple builds ?

The build they provided quick testing shows to have resolved both my issues with GAC folder and citrix WMI classes missing. Will do more tests to make sure it didnt break anything else but first look is good.

Vincent Bernard · July 12, 2022

Hi Sergio. That's good news (so far) and appreciate the testing/feedback. Does Layer export work? Any word from Ctx when they plan GA. 2207 perhaps?

Nick Panaccio · July 12, 2022

Do we just need to submit a ticket to get access to the private fix? I'm caught between a rock and a hard place, because I can't restore from backup at the moment, but need to move forward with my next image.

Id open a call indeed, this issue looks to have been tracked under bug id UNI-87356 , my case number was 81266211 maybe you can reference that case.

Hi,

I will test an export today and get back to you with results. as for GA, I have asked them this question. will get back to this thread once I have an answer.

Damiaan Eppingbroek · July 13, 2022

Also created a ticket and I received the version 22.6.1.1005

When the application is in Image then the application will work.

But we also have some elastic layers like the SCOM Operations Console.

And this is still not fixed in version 22.6.1.1005

The folders are still missing in C:\Windows\Microsoft.NET\assembly\GAC_MSIL

Hi Sergio,

have you already been able to test the layer export? was it succesful?

Sergio Masone1709161115 · July 13, 2022

The build i tested was 22,6.2.1006 so more recent then the elastic layer trouble mentioned with sccm. Nevertheless citrix told me GA will be in 2208 expected in about a month

Thanks Sergio. I think I'll wait for 2208 then.

Yes i exported an app layer to test it and it exported just fine, but i did not test prior to upgrading to the private fix if I had the issue or not.

Nick Panaccio · July 14, 2022

I submitted a ticket with Citrix and asked for the private fix, referencing everything above, and they told me that the WMI issues were fixed with the 2206 build and that I didn't need any private fix. Okay then. Guess it was a good thing I was able to restore my appliance from backup, so I'll hang out on 2204 until the next release.

Thanks for this. I think I'm going to wait for 2208, though, since I was able to roll back to 2204.

Yes, this was experienced with ELM being 2206, while the OS tool was 2202

Good to know that they provides a fix.

My ticket was freeze even before I could provide them with results of the test requested for. Anyway we have since rolled back to 2202 after a long night efforts.

Export worked in our case with the problematic v2206.

Vincent Bernard · July 18, 2022

Upgraded to 22.6.2.1006. Layer export - Working, GAC_MSIL - Working.

App layering 2206, missing citrix wmi classes.
