I am using MS VS 2010 and  Microsoft.NET Framework Version 4.5.50709 SP1 Rel and I have win 8 installed on my PC
and the reason I am trying to install is becuase I want to reference a namespace in the Global.asax file which does not found the BundleConfig in the namespace
and when I am trying to reference it from System.Web.Optimization it giving an error.

this is the code I a using in the Global.asax:

namespace WingtipToys
    public class Global : System.Web.HttpApplication

        void Application_Start(object sender, EventArgs e)
            // Code that runs on application startup
            BundleConfig.RegisterBundles(BundleTable.Bundles); at this line of code

Please can someone help fixing this.

Have you tried it without the -alpha2 part? It doesn't look like a valid version otherwise.

Good luck!
