visual studio 2015 - VS2015 nuget package manager not finding packages

Question

I installed VS2015 Update 2 and now nuget package manager does not find any packages outside of the "Microsoft and .net" package source. It looks like the nuget package source was removed. When I add it back as "http://www.nuget.org" I get an error "Unable to retrieve results from one or more sources".

Anyone else having this problem?

Answer 1

This is a known issue with nuget version 3.4, which is included with Visual Studio 2015 Update 2:

The NuGet.config file in your %AppData%NuGet folder has accidentally been emptied. To fix this: Close Visual Studio 2015, delete the NuGet.config file in the %AppData%NuGet folder and restart Visual Studio. A new NuGet.Config file will be generated and you will be able to proceed.
