When you undeploy an older version of an assembly in Microsoft BizTalk Server 2004, a newer version of the assembly may unexpectedly stop working.
This problem occurs because the GUIDs for the property schema for the assembly are not updated when the newer version of the assembly is deployed. Therefore, a new property schema is not created for the newer version of the assembly. A single property schema exists for the newer version of the assembly and for the older version of the assembly. When you undeploy the older version of the assembly, the property schema is deleted. This causes the newer version of the assembly to unexpectedly stop working.
