title: Cannot find Microsoft.VisualStudio.TextTemplating assembly
body: <p>I am doing some work with T4 (Text Template Transformation Toolkit) and am trying to get to a point where I can create my own custom text template host. However, all of that relies on the <strong>Microsoft.VisualStudio.TextTemplating</strong> assembly and I cannot find it on my system!</p>
  
  <p>I first tried adding a reference to the assembly in Visual Studio, but the assembly for <strong>Microsoft.VisualStudio.TextTemplating</strong> is not listed under the .NET tab. </p>
  
  <p>I then took a look in the <em>%WINDIR%/Assembly</em> directory and found an entry for <strong>Microsoft.VisualStudio.TextTemplating</strong>. However, when I try and browse to this location and add the assembly in Visual Studio, nothing happens. </p>
  
  <p>Has anybody else had this problem? According to MSDN tuts it sounds like this assembly should be included with Visual Studio (and I have VS 2003, 2005, and 2008 installed). </p>
