How use MergeOption in EF 4.1?

Question

Hi,

How use MergeOption in EF 4.1?

Answer 1

Hello,

you cannot use MergeOption with DbContext API. The only available replacement is AsNoTracking extension method for IQueryable with the same meaning as MergeOption.NoTracking. If you want full power of MergeOption you must convert your DbContext to ObjectContext and use ObejctSet and ObjectQuery instead:

ObjectContext context = ((IObjectContextAdapter)dbContext).ObjectContext;
ObjectSet<YourEntity> set = objectContext.CreateObjectSet<YourEntity>();
set.MergeOption = ...;
// Now run the query from the set

You can't because you started this topic as discussion and not a question.
