I am trying to update my Visual Studio 2015 + Cordova + TypeScript project to use TypeScript version to 1.6.0-beta. I am currently using 1.5.3.
Visual Studio 2017 version 15.3<=:
Visual Studio 2017 version 15.2>=:
From the top menu bar, open Tools > Options > Text Editor > JavaScript/TypeScript > IntelliSense
Change Use TypeScript version to your desired version
I had a problem when updating that the version did not fall through. Fixed it by setting a lower version, shut down Visual Studio and then set the newer version. This fixed the problem.
