Hi, I have a map which calls an external assembly wirtten in J#. The map works perfectly in BizTalk 2006(framework 2.0), but when migrated to BTS 2010 it stopped working. I did some research and found some articles mentioning J# no longer supported in .NET Framework 4.0 - I was able to verify this by creating a test console app referencing the same J# dll and tageting framework 4.0. So next I would like to change the target framework in my map project to 2.0, but when I tried to change the target framework in project properties of the Map project, I got the below error:(in Visual Studio 2010 Ultimate)
Attempted re-targeting of the project has been canceled. BizTalk Server 2010 Developer Tools only supports targeting '.Net Framework 4.0'.
Does anyone know if it's possible to change the target framework for a BizTalk 2010 project?
Thanks
Ken
