I created a new development machine and installed BSF with its prerequisites. When I created a new project via the BizTalk Software Factory guidance I received the messages "Microsft.Practices.RecipeFramework.Extensions.Coordinators.ConditionalCoordinator,
Microsoft.Practices.RecipeFramework.Extensions" with as title "Recipe Framework Error". The Guidance Navigator screen showed "Creates unbound references to the BizTalk Software Factory guidance package". In the detailed message
it showed a reference error.
After some strugling I copied the Microsoft.Practices.RecipeFramework.Extensions.dll to the GAC and to the "C:\Program Files\Microsoft Visual Studio 9.0\Common7\IDE\PublicAssemblies" folder. In the project BizTalkSoftwareFactory I referenced the
"GAC file", build and installed the BSF. Now it works fine again.
When searching the internet I couldn't find anything on this. But this did the job for me. Maybe you can have a look at it and share it with others.
