I am thinking of creating a product based on the Visual Studio Shell (primarily isolated mode). Since Visual Studio 2010 will most likely be RTM before my product, does it make sense to start with VS2010 as a base rather than VS2008?
Has anyone looked at what they changed in connection to the shell framework and if it is improved enough to warrant using it over the better documented and not-beta 2008?
The editor extensability model is changed radically since it is based off MEF and WPF in 2010. If you extend the editor on 2008, it is likely you will have to make quite a few changes to get stuff working in 2010.
However, a large amount of the extensability still depends on the old VSIP/COM which remain unchanged.
If you plan on shipping with the 2010 time frame I think skipping 2008 is not a bad idea.
