.NET Continuous Profiler: Exception and lock contention | Datadog

This post details the implementation of exception and lock contention profiling within Datadog's .NET continuous profiler. For exceptions, it describes fetching details like type, message, and location using `ICorProfilerCallback::ExceptionThrown` and `ICorProfilerInfo::GetClassFromObject`. For lock contention, it explains how CLR events like `ContentionStart` and `ContentionStop` are captured, and how duration is computed, including recent contributions to the .NET runtime for richer `ContentionStart` event data. It also outlines strategies for older .NET versions using EventPipe and ETW.
