Hi @ReturiVSSSK 

 

Can you please confirm what version of the OS you're using? The WVD version needs to be Build 19035 or later.

We have tested MSIX App Attach and observed that while the feature works as expected on Windows 10 single session(19035 )

we are facing issues while configuring it on Windows 10 Multi session (win 10 Multi session 1909 ).

 

Detailed comparison and error description in the attached document. Please help with your thoughts over the issue.

@ReturiVSSSK Did you get this working. I too getting the same error on 20H2 build 19042.746.  Any help is much appreciated.
