Consider the following scenario. You add an existing Web.config file to a Microsoft .NET Framework 2.0 ASP.NET Web site. You use the Microsoft Management Console (MMC) Snap-In for ASP.NET or the Web Site Administration Tool to add the file. You open the Web.config file in Microsoft Visual Studio 2005. In this scenario, Microsoft IntelliSense does not work.
This problem occurs because MMC snap-In for ASP.NET and the Web Site Administration Tool add a schema reference to the Web.config file when you add an existing Web.config file to an ASP.NET project.
