What causes POCO proxy entities to only sometimes be created in Entity Framework 4


I have set up my POCOs and I have marked their public properties as virtual and I am successfully getting Proxies most of the time (95%) but randomly I am getting EF return some proxies and some non-proxies.

Recycling the app pool when this happens will then fix this instance of the error and it will go away for an amount of time. Then it will re-occur in some other random (it seems) place.

What can cause this sort of behaviour?

Solution

  • Solved it (im getting in the habit of almost giving up, posting here and then solving it)

    Anyway, when I was adding a new Question i was using something like var q = new Question() this was then being stored as a non-proxy. In the end i found out by creating a new Question on the ObjectContext like so var q = ObjectContext.CreateObject<Question>(); causes it to be a proxy and works just fine and dandy.

    Hope this helps someone,
