WSCF - Schema-Based Contract-First Web Services

It is a free Visual Studio Add-In and Command Line Tool for ImprovedSchema-Based Contract-First Web Services Design and Programming .It offers a simple yet powerful WSDL Wizard that abstracts away all the nitty-gritty details of WSDL and therefore does not give room for making errors and wrong assumptions just by trying to use and applying everything that can be done stated by the original WSDL specification. Plus there are number of new items that primarily made it into the tool based on customer feedback.
