ObjectContext可能处于不一致状态

Question

I have an Error creatting relations whith EntityFramework 4.0

The changes to the database were committed successfully, but an error occurred while updating the object context. The ObjectContext might be in an inconsistent state. Inner exception message: Metadata information for the relationship 'CodeFirstNamespace.EventsIndex_Module' could not be retrieved. If mapping attributes are used, make sure that the EdmRelationshipAttribute for the relationship has been defined in the assembly. When using convention-based mapping, metadata information for relationships between detached entities cannot be determined. Parameter name: relationshipName
