NDC.Push has been deprecated. The preferred way now (ThreadContext.Stacks["NDC"]) is this:

var disposable = ThreadContext.Stacks["NDC"].Push("context");

}
finally
{
  Log.Info("end"); // optional, but nice
  disposable.Dispose();
}

Remember to check your conversion pattern so that it includes %property{NDC}:
