"<MapName.btm>: Exception Caught" error message when you try to use Visual Studio Team System 2010 TFS to build and deploy a BizTalk 2009 project that contains a map that references a schema in another project

Consider the following scenario:
  • You create a Microsoft BizTalk 2009 project in Microsoft Visual Studio 2008.
  • The BizTalk 2009 project contains a map that references a schema in another project.
  • You use Microsoft Visual Studio Team Foundation Server (TFS) 2010 to build and deploy the project.
In this scenario, you receive an error message that resembles the following:
<MapName.btm>: Exception Caught: The map contains a reference to a schema node that is not valid. Perhaps the schema has changed. Try reloading the map in the BizTalk Mapper. The XSD XPath of the node is: /*[local-name()='<Schema>']/*[local-name()='FaultMessage']/*[local-name()='Header']/*[local-name()='Application']
The TFS 2010 build process uses MSBuild 4.0. Assembly references within a BizTalk project can be partly named. Since MSBuild 4.0 loads the .Net Framework 4.0 versions of the assemblies instead of the .NET Framework 3.5 versions of these assemblies, the referenced schemas are not resolved correctly by the BizTalk mapper compiler.
