Visual Studio 2008 Web Deployment Projects is an add-in to Visual Studio 2008 which provides developers with advanced compilation and deployment options. A Web Deployment project is extensible, enabling web developers to create pre-build and post-build actions.
Web Deployment projects do not change the way Visual Studio 2008 Web Sites or Web Application Projects build. Instead, they take an existing Web project as input and generate a precompiled Web as an output. A Web Deployment project does not change the files in the source Web site project in any way either.
Visual Studio 2008 Web Deployment Projects has all the functionalities that Visual Studio 2005 Web Deployment Projects had. Developers can read more about this core functionality at Using Web Deployment Projects with Visual Studio 2005.
However, there are certain enhancements in this release. To learn more about this release, please visit the Visual Studio Web Developer Team Blog.
