SYMPTOMS

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.
