Wiki Page: "The provided URI scheme 'file' is invalid; expected 'http'" when attempting to load a WSDL file in .NET EXplorer

This error will be reported if the WebService needs to be hosted on a Web server before it is able to be imported into .NET Explorer. If this error is reported then the WebService cannot be loaded from the file system (disk). This usually indicates that the more modern "WCF-Import" approach needs to be used rather than the older "SOAP import". If Internet Information Services (IIS) is installed and configured then you should be able to host the file locally using IIS and then load the WSDL by specifying its URL (e.g. http://localhost/test.wsdl) in .NET Explorer.
