Javascript Intellisense and Coloring Issues in VS 2008 Beta 2

  • Article

We have come across a couple of installation issues in VS 2008 Beta 2 which broke the new Javascript functionalities in certain scenarios.  While a workaround has already been provided in the online refresh of the ReadMe text, I thought I would also put it down here in case any of you hit the problem.

Issues

We faced two installation issues which broke Jscript functionality in VS 2008 Beta 2

  1. Uninstallation of Silverlight Tools for Visual Studio 2008 Beta 1 removes the Jscript Authoring DLL
  2. Installation  of Team Explorer Beta 2 corrupts the registration of Jscript

In either case, you dont get to see Javascript intellisense, syntax errors, and javascript coloring does not work.

Workaround

The recommended workaround for both the issues is to Repair the Visual Studio installation by running setup again.  The first issue can be avoided by uninstalling SL Tools for VS Beta1 before installing VS 2008 Beta 2.  The second issue can also be fixed if you dont mind fiddling with the registry.  See the blog post here for details.
