refer to Solution Explorer as from Visual Studio

I found these instructions quite confusing. Specifically, I was stumped when I read the instructions which mention Solution Explorer (I eventually discovered it was a screenshot from Visual Studio). I spent an hour looking for the NuGet package that I had installed and from where I should the run the package; I had no idea whether the screenshot had come from a separate NuGet executable or what. Not all readers come from other instructions or pages referencing Visual Studio. I finally found out that that screenshot comes from the Visual Studio Tools menu. Not everyone ends up at the page from a link or some other source that lets us know that once installed, it is accessible from VS. HTH
