I work on a commercial application that is developed using Visual Studio 2010 Extensibility projects. In this application we have a custom Options Page that holds application related properties. We started migrating our application to visual studio 2015. Most of the migration seems to have gone through well except for a few issues. Once of them is that in VS 2010, on opening an instance of our application, registry entries are created (automatically by the .NET framework) for all the properties managed by the custom options page under a custom registry entry path that is maintained in the .pkgdef and .pkgdef.installer files. However this doesn't happen after migration to VS 2015. On opening an instance of the application or even during debugging, no registries are created and this is causing us problems.
I am not sure if I am missing anything, since the registry entries are supposed to be automatically created under the specified path. Is there a change in the way the options page properties are stored in VS 2015?
PS: For confidential reasons I might not be able to add appliaction related images. I will try to provide as much information as possible if required.
