Well, at the moment, Aspose.Slides installer does not register anything to the GAC and component list automatically, so it is not visible in Visual Studio 2010 component list. We have already registered an issue in our issue tracking system with issue id: SLIDESNET-33731 . However, it is still under discussion whether to implement it or not. I have attached the issue with this forum thread and you will get a notification once the feature is implemented. The process you are following to add the reference manually is fine for Visual Studio 2010.
