ReSharper Plugins

If you feel bounded by the fixed set of ReSharper and Visual Studio possibilities, you can add the features of your dreams yourself with ReSharper API. Bounds on this level are extremely wide - actually, many ReSharper features are implemented using the same API that is at plugins' command. And thanks to its managed nature you can use ReSharper API just as a handy wrapper around messy Visual Studio COM interfaces.

Writing a plugin is quite simple given you are familiar with .NET development. You just compile an assembly containing classes which implement your feature. Then ReSharper automatically plugs them to the right places based on special attributes you mark your classes with.
