Is there an Expression Tree Visualizer for VS 2012? Have had a search but have found the VS 2008 popping up all over the place, and the new VS 2012 doesn't have a Visualizers folder in the installation directory. Or, am I missing something that I should be able to switch on?

Expression trees represent code in a tree-like data structure, where each node is an expression, for example, a method call or a binary operation such as x < y . You can compile and run code represented by expression trees.
Expression Trees provide richer interaction with the arguments that are functions. You write function arguments, typically using Lambda Expressions, when you create LINQ queries. In a typical LINQ query, those function arguments are transformed into a delegate the compiler creates.
What you can do is fix the visualizer for vs 2010 so it works in 2012. This is very easy. Just get the source from this project : http://exprtreevisualizer.codeplex.com/ and change the DebuggerVisualizers assembly reference of the ExpressionTreeViewer project to :
C:\Program Files (x86)\Microsoft Visual Studio 11.0\Common7\IDE\ReferenceAssemblies\v2.0\Microsoft.VisualStudio.DebuggerVisualizers.dll
So that it works with the newest version of vs2012. After that copy the results to
C:\Program Files (x86)\Microsoft Visual Studio 11.0\Common7\Packages\Debugger\Visualizers
and it should work
