Today I am proud to announce svcutil2 - a Wcf proxy generator for Wsdl2. svcutil2, like the original svcutil, generates Wcf proxies from Wsdl2 documents. This is a huge accelerator for web services interoperability. See related discussion here.
svcutil2 is fully open sourced in CodePlex.
How to generate Wcf clients from Wsdl2 documents?
1. Download the latest version of svcutil2.exe from CodePlex
2. Open the VS command console or otherwise make sure the original svcutil.exe is in the current path (usually located in C:\Program Files\Microsoft SDKs\Windows\v6.0A\bin)
3. Use svcutil2 exactly like you use svcutil:
$> svcutil2.exe http://webservices20.cloudapp.net/wsdl2wsdl/wsdl/simple2.wsdl
you can also work with Wsdl's from file system or use any of the svcutil available flags.
