Remarks

Multiple performance measurements may decorate a single method. Additionally, performance measurements found in derived classes overshadow those found in base classes.

MeasurementBoundary is a key difference between the ASP.NET MVC measurements and the ad-hoc and ASP.NET Web API. We allow boundaries to be specified around begin/end and/or action/result.
