EF4 Cast DynamicProxies to underlying object
I'm trying to figure out how to clone or convert a System.Data.Entity.DynamicProxies into it's actual class. Eg:
System.Data.Entity.DynamicProxies.Currency_F4008E27DE_etc is the proxy class
MyApp.Entities.Currency is the real class
All of the classes in MyApp.Entities inherit from BaseEntity, so I tried to do the converting there:
public abstract partial class BaseEntity
{
public T ShallowCopy<T>() where T : BaseEntity
{
return this.MemberwiseClone() as T;
}
// other BaseEntity properties not relevent here
}
And then converting the DynamicProxies into the real class:
// this returns a DynamicProxies class
Currency currency = LookupDefaultCurrency();
// this one needs to return a Entities.Currency class
// (but currently returns a DynamicProxies class too
Currency pocoCurrency = (Currency)currency.ShallowCopy<Currency>();
HttpRuntime.Cache[key] = pocoCurrency;
The reason for this is that I want to remove all Entity Framework tracking and etc from this object and just store its plain (POCO) properties in the cache. And I will need to be able to do this for all 100 or so Entity classes, so it has to be reasonably generic - without manually saying object1.foo = object2.foo for every single property.
