If you saw my posts a few months ago, I was testing BizTalk 2009 compatibility with VS 2010. My earlier posts found that the BizTalk extensions would only load in VS 2008 and not in VS 2010. In this post, I do a refresh of the install experience and give some preview of the .NET 4 features showing up in BizTalk 2009. The same conclusion about compatibility is reached here: the BizTalk 2009 extensions do not work with VS 2010. There is a new workarounds for getting a VS 2008/VS 2010 environment for working with BizTalk 2009.

 

 

Then when configuring BizTalk on the first step for Enterprise Single Sign-On I get an error similar to this (cannot remember exact wording sorry):

 

Cannot connect to SSODB (Win32)

0x80131700

 

I found this blog post about re-regasm-ing the SSOSQL assembly: http://blogs.msdn.com/ashishme/archive/2009/08/14/fixing-biztalk-entsso-failure-on-windows-7-vista-or-server-2008-after-vs-2010-beta-installation.aspx#comments. This helped me get around the error when configuring SSO. It is interesting that the problem occurs when VS 2010 is install prior to or after BizTalk 2009. I was then able to go through the BizTalk configuration wizard successfully. I was able to create BizTalk projects in VS 2008 fine. I did open the VS 2010 extensions manager and check for the BizTalk extensions but they are not showing up there.

 

There are quite a few valuable improvements with WCF 4 such as WS Discovery support, routing, and additional changes to Windows Workflow. All of these will have an impact on the Connected System landscape. Enjoy!
