Bundling and Minification

I try to use the new bundling tool in asp.net 4.5. In global.asax I use:

Code:

Sub Application_Start(ByVal sender As Object, ByVal e As EventArgs)
bundletable.bundles.EnableDefaultBundles()
End Sub

But this generates the following error:
BC30451: 'bundletable' is not declared. It may be inaccessible due to its protection level.

The reason is probably because the package optimalisation needs to be installed (http://msdn.microsoft.com/en-us/vs11trainingcourse_aspnetandvisualstudio_topic5#_Toc319053053).

Why is one of the best new features not automaticly installed? Is the feature installed on the final version of asp.net 4.5?

 

Ok, thanks.

I copied:
microsoft.web.optimization.dll and
microsoft.web.infrastructure.dll
to the bin directory and I adjusted global.asax:

No, it works. It needed the infrastructure.dll as well. Strange, it looks like a standard file to me. I found it on my computer (beta VS 2011 installed).
