EF Beta 2: can't find ObjectContext extensions (e.g. ApplyChanges)

Question

There was a really nice extension in EF4FeatureCTP1 named ApplyChanges. Where did it go to?

Answer 1

Check the following post from the ADO.Net team blog:

This CTP1 is not compatible with EF 4 Beta2, since it has some breaking changes (ex: DeferredLoadingEnabled is deprecated).

Answer 2

It actually IS compatible with Beta 2, I'm using it in production now. You have to change the Microsoft.Data.Entity.CTP reference to "CopyLocal", and change the Context template to:

ContextOptions.LazyLoadingEnabled = true;

instead of "DeferredLoadingEnabled". After that, everything works as expected.

Scratch that, no it doesn't. Trying to put together a workaround now.
