I haven't had this problem until recently and I want to make sure it isn't something on my end.
Steps to reproduce:
- Add a new ASP.NET Core 1.0 web application project in VS2015.
- Click show all files and open bower.json.
- Change the version of bootstrap to version 3.3.6 and save the file.
You will see at the bottom of the screen that it says:
'An error occured installing packages. See output windows for details.'
I noticed that if you try changing any of the default versions this error appears.
Additionally there is no intellisense working for the version #'s after the ':' I just see a '*'.
The only thing I can think of is that ReSharper is interfering with it...
Please let me know if anyone else is having this issue with the latest version of VS2015 Community Update 2.
