I installed your plugin in Visual Studio 2010, and I created a project of type "Console application with IL support". When I open the Program.il file that was automatically created with the project, there is no syntax highlighting, but there is in your screenshot. How do I turn on syntax highlighting ? Thank you.
I just had the chance to test on Visual Studio 2010. The modifications applied to support Visual Studio 2012 have introduced a bug making the syntax highlighting throw an exception on Visual Studio 2010, thus disabling it.
I will fix this bug in version 2.1 as soon as possible. Meanwhile, everything should still compile correctly.
