Some information relates to prerelease product that may be substantially modified before it’s released. Microsoft makes no warranties, express or implied, with respect to the information provided here.
When overridden in a descendant class, indicates whether to pre-authenticate the request.

true to pre-authenticate; otherwise, false.
Exceptions
Any attempt is made to get or set the property, when the property is not overridden in a descendant class.
Remarks
Caution
WebRequest, HttpWebRequest, ServicePoint, and WebClient are obsolete, and you shouldn't use them for new development. Use HttpClient instead.
With the exception of the first request, the PreAuthenticate property indicates whether to send authentication information with subsequent requests without waiting to be challenged by the server. When PreAuthenticate is false, the WebRequest waits for an authentication challenge before sending authentication information.
Note
The WebRequest class is an abstract class. The actual behavior of WebRequest instances at run time is determined by the descendant class returned by the WebRequest.Create method. For more information about default values and exceptions, see the documentation for the descendant classes, such as HttpWebRequest and FileWebRequest.
