Entity Framework deleting linked table

Question

If I have the following setup

public class Device
{
    public virtual ICollection<Folder> PresentInFolders { get; set; }
    public virtual RoutingRule RoutingRule { get; set; }
}

public class Folder
{
    public virtual ICollection<Device> Devices { get; set; }
}

Is the following code enough to disassociate and delete all linking rows?

foreach (var folder in device.PresentInFolders.ToList())
{
   folder.Devices.Remove(device);
}
device.PresentInFolders.Clear();

Answer 1

As i can see you have setup a many to many relation between Device and Folder. It should not be necessary to delete from the two ends of the relation so this should do the job:

folder.Devices.Clear();
