We have a very large solution project for our MVC structure where I work. I am trying to filter my solution explorer down to only relevant files with a custom filter. Microsoft has an article on making a custom filter here, but when I try to build the source code they give it says one of the .NET Framework namespaces is not available (I have already reinstalled .NET). The namespace that won't resolve is: System.ComponentModel.Composition. I am hoping fixing this will allow me correctly build a filter (there are 5 errors in the project total).
I definitely have the 2012 SDK installed (you won't make it far in the tutorial without it).
