SYMPTOMS
Consider the following scenario. You open a Microsoft Visual Studio 2005-based Web application by using a URL. The URL is specified by a combined host name and port number. For example, the application is opened at the following URL:

http://

In this scenario, IntelliSense for the System.Web namespace does not work. The list of methods and properties does not appear if you type System.Web.



CAUSE
This problem occurs because of the colon in the URL. When you open the application, the Visual Studio IDE creates an HttpRuntime object by using the server name as the virtual path. For example, if the URL is http://, the virtual path will be / /. However, colons are invalid in a virtual path.

Additionally, the virtual path is used to build the file path. Colons are also not valid in a file path.
