Microsoft has announced the Release Candidate edition of the Microsoft Soap Toolkit Version 2 (Soap Toolkit 2.0 RC0). The RC0 Toolkit "offers functionality similar to the MSDN Soap Toolkit sample which has been available for several months, but it will be a fully Microsoft-supported product. The GOLD release of this Toolkit will replace the current MSDN Soap Toolkit. The major enhancements since the Beta 1 release include: (1) A new ISAPI listener. (2) Security fixes and enhancements including Proxy Authentication and some SSL fixes. (3) Support for messages with complex types in the WSDL description. This is implemented using a Nodelist in the API or through a custom type mapper. (4) Support for simple arrays. (5) WSDL enhancements including stricter standards conformance and broader datatype support. (6) SDLGen can now generate WSDL for multiple COM objects in the same dll and allows selection of methods within each interface. (7) A new trace tool is provided to simplify troubleshooting. (8) C++ samples are now available."

From the product description page: "Additional enhancements included in the RC0 release include: (1) Support for Soap Headers has been incorporated into the high-level API. Header support was previously only available in the low-level API and SMO. (2) Arrays of Complex Types are now supported. (3) Multi-dimensional arrays are supported. (4) The WSDL handling and type mapping code has been modified to support the changes to datatypes in the 2001 XSD recommendation. For interop with systems that support the previous XSD recommendation, you may optionally use the older namespace. The samples for the Soap Toolkit 2.0 Beta 2 release are provided in a separate install program to simplify distribution of the toolkit files..."
