As you probably know, Visual Studio 2010 Service Pack 1 has been released and is now available for download. It fixes many issues in VS 2010. But the most interesting for me, as a VS help tool developer, is the new version of VS 2010 help - Microsoft Help Viewer (MSHV) version 1.1. This new version contains new local help viewer which was really awaited by users of our VSdocman.
VSdocman is able to generate technical documentation in MSHV format and it can integrate it in VS 2010 help. By default, VS 2010 Help opened in your default web browser. However, viewing in the browser provided only limited functionality - no full TOC, no Index. So we advised our customers to use free third-party H3Viewer.
As mentioned above, VS 2010 SP1 installs its own help viewer which has expandable table of contents, index and other nice features. There's no need to install any third party help viewer anymore. Really good news.
Note: The latest H3Viewer.exe is compatible with the new help system and still contains several extra features.
