I'm using R Tools for Visual Studio (RTVS version 1.0.30321.1407) in Microsoft Visual Studio Professional 2015 (version 14.0.25431.01 Update 3). I've been using R version 3.3.1, but today I installed R version 3.4.0.
My RStudio was smart enough to now point to the new version of R, but my RTVS is still pointing to the old one.
How do I get RTVS to point to the latest version of R?
Addendum: The solution is not to simply uninstall the old R from my machine. That just makes Visual Studio hang for what seems like forever upon startup.
