.Net MAUI - WinRT information: No COM Servers are registered for this app

I'm working on a .net MAUI project. Set to release, I can build and deploy my project, and created a publish .msix for the Microsoft Store.

I received an update from Visual studio 2022 (17.14.9), and installed it.

When I wanted to deploy my app to create screenshots, it failed with this error:

WinRT information: No COM Servers are registered for this app.

I didn't change anything on my project.

None of them resolved my issue.

So, how to fix this issue?

Solution

  • My issue concerned the CommunityToolkit.

    I was using Toast on Windows

    My package.appxmanifest was broken.

    The value inside the field "Executable" of <com:Extension Category="windows.comServer"> was "YOUR-PATH-TO-EXECUTABLE".

    <Applications>  
<Application Id="App" Executable="$targetnametoken$.exe" EntryPoint="$targetentrypoint$"\>  
  
  <uap:VisualElements  
  
    DisplayName="$placeholder$"  
  
    Description="$placeholder$"  
  
    Square150x150Logo="$placeholder$.png"  
  
    Square44x44Logo="$placeholder$.png"  
  
    BackgroundColor="transparent"\>  
  
    <uap:DefaultTile Square71x71Logo="$placeholder$.png" Wide310x150Logo="$placeholder$.png" Square310x310Logo="$placeholder$.png" /\>  
  
    <uap:SplashScreen Image="$placeholder$.png" /\>  
  
  </uap:VisualElements\>  
<Extensions>  
<!-- Specify which CLSID to activate when notification is clicked -->  
<desktop:Extension Category="windows.toastNotificationActivation">  
   <desktop:ToastNotificationActivation ToastActivatorCLSID="6e919706-2634-4d97-a93c-2213b2acc334" /\>  
</desktop:Extension>  
<com:Extension Category="windows.comServer">  
                <com:ComServer\>  
  
                    <com:ExeServer Executable="MyApp\\MyApp.exe" DisplayName="$targetnametoken$" Arguments="----AppNotificationActivated:"\>  
  
                        <com:Class Id="6e919706-2634-4d97-a93c-2213b2acc334" /\>  
  
                    </com:ExeServer\>  
  
                </com:ComServer\>  
  
            </com:Extension\>  
</Extensions>  
</Application\>  
</Applications>

    I changed it with "MyAppFolder/MyApp.exe", and it resolved my issue.
