Add-on Studio for World of Warcraft Based on VS Shell
VS Shell is a free version of Visual Studio designed to be used as a framework for developing applications. Applications are built as add-ons for Visual Studio Shell, which can be distributed royalty free.
While applications do not have be of the compiler/IDE variety, they are the natural target for VS Shell. A notable example in the end-user space is the Add-on Studio for World of Warcraft.
Add-on Studio for World of Warcraft was developed in roughly two weeks by two developers. Features include a visual design surface and auto-generation of table of content files.
One of the more impressive features is how easily Intellisense for Lua was added. Lua is a scripting language popular among games such as World of Warcraft, Dawn of War, and Far Cry. Property and event panes for Lua are also supported.
