Just spent half an hour trying to install a nuget package…. everytime Visual Studio 2015 would crash. I figured I mustn’t be alone, so I went hunting. Turns out that whilst I had the most recent extension available on the VS Gallery, it wasn’t actually the most recent. Anyhow – if you go here there is a link to an updated vsix file which fixed all my issues.
