Platform Notes

Silverlight for Windows Phone Silverlight for Windows Phone

 Silverlight for Windows Phone, does not use the same underlying messages. Do not ascribe any meaning to the Timestamp numeric value. Limit your use of the value to scenarios where you compare two Timestamp values. The greater value represents a touch event that happens subsequent to the lesser value. In some cases, it is possible that Timestamp reports a negative value, but the deltas will still be representative of a normal time progression.
