Advanced PowerShell Eventing Scripting Techniques
summary
Claims that PowerShell lacks a full scripting environment inside event handler scriptblocks and offers concrete workarounds: uses WMI intrinsic/extrinsic events, Win32_ModuleTrace logging to capture DLL loads (writes to file/event log), timers and engine idle events, delegates like ServerCertificateValidationCallback override to accept bad certs, and async/unmanaged callbacks to emulate a simple web server. Explains a reflection-only assembly resolve hack that sets a nonpublic field to attach a handler. Demonstrations work but require hacks: globals, files, or wrapper Register/Get/Unregister commands to persist or retrieve objects.
