Remarks

The key resolver service is used when related entities are persisted in a context where only one of a particular relationship can exist at the same time. The GetKeyExpression(TModel) is intended to return the LINQ expression to filter the existing dataset to determine if the specified object already exists. The TModel should always be an IDbIdentified instance which has an actual primary key (surrogate key) and should not be used on objects which have composite keys. If using this resolver implementation to resolve a IAnnotatedResource instance then the same applies.
