Hi, just to say my personal point of view as the author of Code Snippet Studio.
The tool does not claim to be running under VS 15 Preview, as it has been developed with and for 2015. I agree that existing extensions should have less compatibility issues, but I'll be waiting for an RTM version before investing time on that. It's too soon to start working on a preview that might be subject to changes ;)
Hi, I don't actually think there are any problems with this feature. Probably it's not the default because it assumes you are connected to the Internet, but I'm not sure about this. Thanks for watching the video.
