When I selected Tools | Library Package Manager | Manage NuGet Packages for Solution, I first see the disquieting intelligence: "The remote name could not be resolved: 'packagesource'
Nevertheless, I forged ahead, and tried to install SignalR, Json.Net, and HTML Agility Pack, yet each time I got the message:
"NuGet failed to install or uninstall the selected package in the following project(s)."
Nevertheless, packages.config contains:
<package id="Microsoft.AspNet.SignalR.JS" version="1.1.2" targetFramework="net40" />
<package id="Newtonsoft.Json" version="5.0.6" targetFramework="net40" />
...so what's up? Did they install or not?
