In my ASP.NET website all calls into the data layer return entities as interfaces and the website does not need to know what the concrete type is. This works fine, but I have run into a problem when trying to store one of those types into the user Profile. My
interface implements ISerializable, like the following:
public
interface IInsured : IPerson, IEntity, ISerializable
and the concrete type in the datalayer does implement ISerializable. My Profile property in web.config is:
<add name="ActiveInsured" type="FacadeInterfaces.IInsured" serializeAs="Binary" defaultValue="[null]"/>
It compiles just fine, but I get a runtime error on Profile.Save() saying that the
interface cannot be serialized. I have also tried it with serializeAs="Xml". I thought that if my
interface implemented ISerializable it would work.
Anybody had this problem before or know of a workaround?
