Some times on ApplicationSuite module when a new element is added to the current Visual Studio project (or new one) and incremental compilation is done from the project, the assembly generated is produced in a way that the InventMovSubtype_Value enumeration type is lost from the manifest, producing this error at runtime where some functionality across the application is broken (any reference to this enumeration is going to throw TypeNotFound exception).
In order to workaround it is needed to do a full build over application suite.
