I was stuck with the same problem and Kristofer's code worked perfectly, many thanks!

In case someone is interested, I slightly modified his code so that instead of accepting the target entity as a parameter, it creates a new object and returns it. Also I have made the sourceEntity parameter to be generic:

 public static T CloneEntity(this DataContext dc, T sourceEntity) where T:class, new()
 {
     var targetEntity = new T();
     //... original method code...
     return targetEntity;
 }

Then I can do the following:

dataContext.MyEntities.Attach(dataContext.CloneEntity(theEntity));
