I have Visual Studio 2012 Express for Web. My Steps -Create a New ASP .NET MVC 4 application -choose basic template -go to Package Manager Console -try to install WebActivator
PM> Install-Package WebActivator
and i get the following error
How i can resolve this and install WebActivator package?
In my case, I could not install any package and got a similar error. The issue was solved as I unchecked the "Microsoft and .NET" under "Machine-wide package source":
I hope this can be help someone.
