Debug Inspector for Windows

Debug Inspector is a Visual Studio Extension (on Visual Studio Gallery), a stand alone Studio EXE for unmanaged deadlock detection, and soon to be a SharpDevelop IDE AddIn, that allows you to view the call stacks of multiple threads at the same time, plugs in to the internals of the CLR and automatically detects deadlocks. It allows you to see exactly what the CLR is doing under the hood and shows, for each thread, the monitors (SyncBlock) owned and the monitor waited on, if any.

Version 1.23 includes unmanaged DeadLock detection (beta) via the DebugInspector.Studio.exe executable.
