Many people are waiting for a way to type rich text. Even if I think that Microsoft will bring out their own one, nobody knows how long to wait for and which features are included. My RTE ships with various common features and an extensive documentation. Please note that the whole thing is still in BETA state and there are some weird bugs on XP and different ones on Vista. It seems as if they are not caused by my component at all, because Visual Studio would notify me. So wait for the final version of Silverlight 2, until you use this component in any production environment! It is of course possible that some things are still undocumented or documented ones will not behave as expected. Don’t hesitate to report such incoherencies.
