wxVisualSetup enables Intellisense.
Microsoft Visual Studio versions 2002 and 2003 Intellisense Parser cannot handle the wxWidgets #include structure properly. Most of the wxWidgets symbols are unavailable for Intellisense.
To solve this, wxVisualSetup installs a special file containing all the neccessary information.
Include _wx_intellisense.h in your projects to make Intellisense work again.
Note: Intellisense has been improved in Visual Studio 2005, so this workaround is no longer necessary.
