For all you guys developing BizTalk 2009 solutions a hotfix was brought to my attention by Thiago Almeida’s blog.
From the Microsoft support site:
“FIX: You experience various problems when you develop a BizTalk project that references another BizTalk project in Visual Studio on a computer that is running BizTalk Server 2009”
On a computer that is running Microsoft BizTalk Server 2009, you use Microsoft Visual Studio to develop a BizTalk application. In your BizTalk project, you add a reference to another BizTalk project. In this scenario, you may see the following behavior:
- The orchestrations in the referenced BizTalk project may show compiler warnings.
- The changes that are made to the referenced BizTalk project are not propagated on to the referencing project.
- When you edit the orchestrations of the referenced project, XLANG errors are thrown. These errors may disappear after the orchestrations are saved and recompiled.
- After you deploy the referencing project, the local copies of the referenced project’s binaries are deleted.
- After you deploy the referencing project, various errors or warnings occur in Orchestration Designer.
