Isolated Shell application created using Visual Studio 2013 SDK does scan for new extension when called with Applicationame.exe /setup

Hi,

We have new isolated shell application created using Visual studio 2013 SDK.

We created a custom extension for the isolated shell. We manually extracted extension's vsix content into isolated application's extension folder (Not using VSIXinstaller.exe because it will be an msi installer later ).

The isolated application does not  load the extension. We tried running <applcationname>.exe /setup still not loaded.

If we update "ExtensionsChanged" registry key for the application, it seems to detect and load the extension.

As "ExtensionsChanged" key is an internal we would like to avoid using it.

Is there any way to make  "<applcationname>.exe /setup" to detect extensions for isolated shell applications  ?

Thanks,

:-)
