The .NET Web service engine can handle the XML-type array datatype. It also supports the transmission of security constraints in the header sections in the SOAP message envelope.

The .NET Web service engine supports the latest Web service standards. To use this engine, you must have the wsdl.exe Web service tool on the development computer. This tool is required to parse WSDL files and generate C# code for a .NET assembly. The wsdl.exe file installs with the .NET SDK. It is not required on deployment computers, although deployment computers must have the .NET 2.0 Framework to consume a Web service that depends on the .NET Web service engine.
