Refresh entity instance with DbContext

Question

With EF4 CTP5 DbContext, what is the equivalent of this

    public void Refresh(Document instance)
    {
        _ctx.Refresh(RefreshMode.StoreWins, instance         


        

Answer 1

I found that the reload fails on proxy entities that have navigation properties.

As a work around, reset the current values and then reload like this:

var entry =_ctx.Entry(instance);
entry.CurrentValues.SetValues(entry.OriginalValues); 
entry.Reload();
