Major BizTalk Incompatibility – IIS 7 and WCF Publishing Wizard

On my current project the client has been dabbling with BizTalk 2006 R2 in a very unsupported configuration with Windows Server 2008, and SQL 2008. In previous posts I talked about Windows Server 2008 and some challenges installing BizTalk on this OS. Generally, Windows Server 2008 behaves well for BizTalk. SQL 2008 has behaved well and has not presented any problems for BizTalk other than the fact that it does not include Notification Services so you must install this optional component from the installer included with SQL 2005. This post describes some new difficulties I have identified when using BizTalk Server 2006 R2 with IIS 7.
Working in the unsupported environment has been very interesting because it has identified that there are issues with BizTalk’s WCF integration on Windows Server 2008. Windows Server 2008 includes IIS 7 which has been overhauled extensively. Several issues have been identified with IIS 7 and BizTalk Server 2006 R2:
– It is possible to run the BizTalk WCF Publishing Wizard through completely to create a .svc WCF endpoint and a virtual directory to host the WCF service but by default IIS 7 is not configured to support the .svc extension. In order to setup the .svc extension, use the IIS 7 directions at
– When running the BizTalk WCF Publishing Wizard sometimes IIS 7 will get dumped out completely. From time to time running the wizard the web.config at c:\Inetpub\wwwroot and all of the virtual directories in this folder get removed during the time that the WCF Publishing wizard is running. For this reason, I strongly recommend you backup the web.config in the web root and all virtual directories stored under the web root before running the WCF Publishing wizard on a box that includes IIS 7. If you just registered the .svc handler and IIS 7 gets dumped out you will need to create it again. Due to this issue, I also strongly recommend that if you need to work with HTTP or IIS related adapters, use Windows Server 2003 R2 with IIS 6 rather than Windows Server 2008 with IIS 7.
– The BizTalk WCF Publishing Wizard may require additional permissions when run on Windows Server 2008 than on Windows Server 2003 due to the secure by default nature of IIS 7. I identified issues with the NetMSMQ binding and MEX-only endpoints created with the BizTalk WCF Publishing Wizard in which permissions must be loosened while the wizard is running although they may be tightened afterwards.

Variation on WSS Adapter Error & Workaround

On my current project I was working to configure the WSS adapter for BizTalk on a separate server than BizTalk. This requires running the BizTalk installer on the SharePoint box and then running the BizTalk Configuration Wizard to setup the WSS adapter web service. I was running the configuration wizard and was just using the defaults and received the following error:
d:depot2300mercuryprivatekwsourcebizofficecodebizofficeconfigurationwssadacfgwssadacfg.cpp(467): FAILED hr = 80070002

This is a similar error to the one reported at but I identified a different workaround that did not require an updated DLL from Microsoft. Rather than use "Default Web Site" as the application where the WSS adapter web service should be installed, I used an already existing web site such as "SharePoint – 80". This enabled me to install the WSS adapter successfully.
While discussing this issue I wanted to mention that the WSS adapter configuration instructions at mentioned that you needed to install "Windows SharePoint Services SP2" but this refers to WSS 2 SP2 and is not required if you currently have WSS 3.

BizTalk WCF Receive Adapters Wrap SOAP Body Content

On a recent project I was exposing a BizTalk orchestration as WCF for a Windows Forms client and a Windows Mobile client. For simplicity, a single BizTalk receive port was being used with multiple WCF receive locations. The BizTalk WCF publishing wizard allows this type of functionality through running of this wizard more than one time. This is by far one of the coolest WCF capabilities in BizTalk – the ability to expose multiple bindings (like you can do in WCF) for each BizTalk orchestration. For example, one BizTalk orchestration can be exposed for both a WCF-BasicHttp binding and a WCF-NetMSMQ binding through running the WCF publishing wizard twice, once choosing to publish a service endpoint for the WCF-BasicHttp binding, and then a second time as a Meta-data endpoint (MEX) for the WCF-NetMSMQ binding.
The message body properties for both of these receive locations was set to "Body" which is supposed to pull out the contents of the SOAP:Body from the WCF service call. When testing both of these bindings the contents of the SOAP:Body were being output but they were being wrapped in a part element like in the message given below:

<part i:type="a:string" xmlns:i="; xmlns:a="">Hello World!</part>
The application that was being implemented was one in which the body data needed to be passed along intact and not further wrapped. The MSDN documentation on the Message Body properties ( did not mention that additional data would be passed along to wrap the content that was passed to the WCF receive location. The additional part element caused problems with the next system to receive the message. So I used the Path option rather than Body for the message body and used the XPath expression of /*[local-name()=’part’] to remove the additional wrapping of the data. This provided what I would expect to be included in the body part of the SOAP:Body – the data passed to the WCF operation and nothing more.
This tip should help you avoid one challenge of working with the new WCF features of BizTalk. Thanks!
