WYSIWYG page editor.
Visual InterDev 6.0 includes a new page editor designed specifically for professional developers. The editor provides support for the full range of current browser technologies including generic HTML, Dynamic HTML, and additional add-ins such as Java applets, Microsoft ActiveX® controls, and Netscape plug-ins. It provides maximum control of the appearance of the HTML while still allowing complete access to the source code, without sacrificing the formatting of the source code.
Seamless debugging tools.
The most widely requested feature from users of Visual InterDev 1.0 was better support for debugging. The distributed nature of Web applications requires that developers be able to seamlessly debug application logic across both the client and the server, and attach to and debug processes running on remote servers. Developers can now set breakpoints on both client- and server-side script, step through code, add "watch" variables, investigate the call stack, and debug remote Web servers.
Site design and management tools.
Visual InterDev 6.0 includes a powerful set of features to simplify the creation and management of the site. It enables developers to create sites quickly, add existing and new content to a site, create and manage hyperlinks between pages, and deploy the site quickly and easily from staging to production servers.
Customizability and extensibility.
The new IDE allows developers to tailor their development environment to their own styles and work environments. It also provides a rich extensibility model that enables both individual developers and third-party ISVs to extend the development environment with specialized components. Furthermore, the IDE supports an extensible model that allows developers to use the editors of their choice on the full range of file types found in Web projects.
