Custom TraceSource and debugging using IntelliTrace

This post introduces a method to integrate custom TraceSource events into IntelliTrace's data capture. It provides a concrete implementation of a custom TraceListener (`TraceListenerForIntelliTrace`), demonstrates its configuration within `app.config`, and details the necessary modifications to the IntelliTrace collection plan XML (`collectionplan.xml`) to recognize the custom listener and its `WriteMessage` method. It also outlines how to apply these changes for various debugging environments (local debugging, standalone collector, MMA, Azure).
