BiztalkWscfClient for Biztalk 2006 is out! The tutorial (http://geekswithblogs.net/mtex/articles/68630.aspx) and tool description (http://geekswithblogs.net/mtex/articles/68626.aspx) are updated. The new version can be downloaded from http://www.gotdotnet.com/Community/UserSamples/Details.aspx?SampleGuid=7762029C-D865-4A7C-8DB2-33B76CB52891.
The first version got 525 downloads till now. I hope the new one will have at least the same number.
As always, I'm waiting for you feedback.
