my name is Selma Ikiz and I am a PM for the New Code Editor in Visual Studio.
We have created a set of walkthroughs for the Visual Studio 10 release, please use these walkthroughs as a guide to familiarizing with this release. Given that this is the first release of Code Editor in Visual Studio, we are excited to hear your feedback.
Walkthrough: How to Add Syntax Coloring in the Visual Studio 2010 Editor
You can add many different visual effects to the Visual Studio 2010 editor by creating Managed Extensions Framework (MEF) components. This walkthrough shows how to add syntax coloring.
We hope you find the walkthroughs useful and you can use the Connect website to report bugs.
Apologies for the delayed response. To answer your questions: Visual Studio certainly has syntax coloring enabled for many languages by default. The sample Selma posted about is meant to show how you can implement customsyntax coloring, whether for your own language service or to customize the text formatting beyond what's available through Tools-->Options-->Fonts and Colors.
I understand not wanting to install the CTP in March, as it was several months old at that point and required a large download. However, I would encourage you to download the VS 2010 Beta when it is released very soon. You should see significant improvements from the CTP in almost every aspect of Visual Studio 2010. There will be feedback forums for the beta as well, and I hope you'll post again to share more feedback.
