asp.net core - Package restore failed. Rolling back package changes

Question

When I am trying to install any nuget package in VS2017 for asp.net core. it is constantly showing "Package restore failed. Rolling back package changes" for each package.

Answer 1

You can do the following steps:

1. VS Tools
2. Options
3. Nuget Package Manager
4. General
5. Clear All Nuget Cache(s).

OR

You need to change target .net core 1.1 to 2.0, and this is possible if you update your VS 2017 with the latest version(ex. VS 2017 15.3)
