c# var type display VS extension

hi,
I was asking about your opinion of the vs package to display the var types inline over the var keywords at the start of the stream today. i had to continue working, so i couldn't stay, sorry.
I'm thinking about what to do with that extension. it's in my vsts, not on GitHub, so i cannot link it and i haven't yet decided whether to open source it (because some of my colleages think it could become a product). i'd be glad to show it.
