cannot create BizTalk 2009 projects in Visual Studio 2008?

I got a query from another customer with regards to this - this has nothing to do with BizTalk 2009 - check if you installed the VS after BizTalk server? You need to install VS before BizTalk. Alternatively, you could choose to install the Developer tools & SDK section of the BizTalk server components again from the media kit for BizTalk server (you may have to un-install this component first and then re-install OR Repair as suggested by Thiago)
