A number of screencasts on Office development have been posted on Channel 9 Shows >> In the Office. I've created two of the screencasts that show the new functionality of the June CTP of Visual Studio Tools for Office. (Customizing the Ribbon with Microsoft VSTO "v3" June CTP and Custom Task Panes in Microsoft VSTO "v3" June CTP). You can find these screencasts at https://channel9.msdn.com/Shows/In_the_Office
