ORM Profiling Tools for the .NET Platform

by Jonathan Allen on  Nov 16, 2009 5

Sadly the terms “ORM” and “performance problems” often travel together. By hiding the underlying SQL from the developers, ORMs can offer a huge productivity boost. Unfortunately they also make it easy to generate ridiculously bad queries without realizing it. And without stored procedures to cross reference, finding the offending code without an ORM-specific profiler can be quite tricky.
