Remarks

Use the VSWebSite interface to manipulate a Web site project from either a macro or from an add-in to Visual Studio.

Besides the properties and methods in this class, there are more properties for Web site projects available using the WebSiteProperties class.

Note

The functionality provided by this class is available in versions of Visual Studio starting with Visual Studio 2005. It is not available in Visual Web Developer Express Edition.

Examples

The following example shows how to use an add-in to interact with a Visual Studio Web site project. The add-in uses event handlers to write to the event log when either a reference to an assembly or a Web reference to a Web service is added to the project. In addition, it writes a summary of each Web site project to a text file when the solution is closed.

To run the example, use the How to: Create an Add-In to create an add-in project, and replace all of the code in the resulting Connect.cs file with the sample code. You will also need to create a reference to the VsWebSite.Interop assembly.
