Hotfix for assembly reference issues with BizTalk Projects in Visual Studio 2009

When working with a BizTalk solution, I ran into these issues a lot of times.

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.

A colleague then metioned about this hotfix - KB 97748. After installing this, the references do work like a charm.
