The main goal of this release is to introduce the Visual Studio 2010 extension package that integrates the Sandcastle Help File Builder with Visual Studio. With it, projects can be created and managed from within Visual Studio just like any other project
type supported by it.
This version is an Alpha release. Project management support has been implemented but some of the file editors are currently not implemented. See the
Important Information section on the download page for more information. If you have any problems, please report them in the Discussions forum or Issue Tracker at the
Sandcastle Help File Builder project site. Please be sure to specify the version number you are using to keep the issues separate from the current production release. Thank you!
