Entity Framework 4.1 - Refresh is not a member of Context

Question

I'm trying to revert Context changes using the Context.Refresh method but It seems like Refresh is not a member of Context.

I'm using the Microsoft ADO.NET Entity Framework 4.1 RC version.

Any idea?

Answer 1

You are likely looking at a DbContext, which does not have a Refresh method. You can use the IObjectContextAdapter interface to get the underlying ObjectContext, and call Refresh on that.

var objectContext = ((IObjectContextAdapter)context).ObjectContext;

Answer 2

You can also use the Reload function on the Proxy Objects... Here is a sample to reload all modified objects:

            var modifiedEntries = context.ChangeTracker.Entries()
                .Where(e => e.State == EntityState.Modified);
            foreach (var modifiedEntry in modifiedEntries) {
                modifiedEntry.Reload();
            }
