Add components for "Code Map" , "DGML Editor", and ".NET Compiler Platform SDK"
Open a C# Code file.
Open View -> Other Window -> Syntax Visualizer
Select a variable declaration statement in the C# code.
Right click on the node in the visualizer and select View Directed Syntax Graph.
Visual Studio crashes and reboots.
