As it is reported on http://blogs.msdn.com the pack VSTA will allow the independent developers and creators of corporate applications on Visual Studio to enlarge the functionality of their products by providing the users with advanced features of writing specific macros and scenarios. For example, the new version of Microsoft InfoPath 2007 is supplied with already integrated tool VSTA. In order to evaluate its capabilities, the user only has to create InfoPath form, and open the development environment of VSTA through keyboard combination “Alt-Shift-F12”. The set includes all the necessary documentation and code samples.
