Um ... MetricPoint Um.. wtf?

Created a customer exporter to write to a CSV file and happened to look at the source code for the MetricPoint class.

ThrowNotSupportedMetricTypeException is used to throw a NotSupportedException

Um using an exception like this is an indication of badly designed code, hopefully this is already know and its going to be fixed in a future updates. Its also bad for performance if these exceptions get triggered at runtime.

I considered posting to The daily WTF as yes its that bad so hopefully this is planed to be fixed.
