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?
So easy
https://www.nuget.org/packages/WebActivator
Need point version of webActivator!!!
I got a similar problem with another package in Visual Studio 2013, I cleared the NuGet package cache with the option "Clear Package Cache" and it works now.
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.
I just ran into this myself. The reference to WebActivatorEx didn't work. You'll have to do it manually. The file is in the packages directory.
Change source according to visual studio version
