Unable to find specific NuGet packages after update

After updating Visual Studio 2015 (there was an update for GitHub Extensions, one for the NuGet Package Manager and, of course, there was Visual Studio 2015 Update 2) I tried to add the WindowsAzure.Storage NuGet package to a project I started about a month ago. I opened NuGet Package Manager, went to the Browse tab and typed WindowsAzure.Storage. The result: No Packages Found. OK, so then I’ll just….

Wait… WHAT?

No Packages Found

After doing all sorts of things, including looking for other NuGet packages with the same result, I found what the issue seemed to be: the Package Sources weren’t up to par, since the Official feed had vannished. I fixed them and then set the ‘Package source’ to be ‘All’ in the upper right corner of the NuGet Package Manager. Fixed it for me!

Hope this helps.
