When working with Entity Framework entities, most of the time we operate on entity model entities, a combination of database manipulation contexts that can be easily implemented using a variety of convenient means, such as LINQ, and everything looks good. However, if you consider using WCF, you may encounter a number of related traps or errors. Because the object of the

The next question is who will handle this complexity. The answer is that if you are crazy, you can solve it by yourself. Otherwise, you can use the O/RM tool, or more specifically, the Entity Framework.
