Serializing Entity Framework problems

Question

Like several other people, I\'m having problems serializing Entity Framework objects, so that I can send the data over AJAX in a JSON format.

I\'ve got the following

Your error occured due to some "Reference" classes generated by EF for some entities with 1:1 relations and that the JavaScriptSerializer failed to serialize. I've used a workaround by adding a new condition :

    !p.Name.EndsWith("Reference")

The code to get the complex properties looks like this :

    var complexProperties = from p in type.GetProperties()
                                    where p.CanWrite &&
                                          p.CanRead &&
                                          !p.Name.EndsWith("Reference") &&
                                          !_builtInTypes.Contains(p.PropertyType) &&
                                          !_processedObjects.Contains(p.GetValue(obj, null)
                                            == null
                                            ? 0
                                            : p.GetValue(obj, null).GetHashCode())
                                    select p;

Hope this help you.
