Coded UI Test Extension for 3rd party Windows Forms controls–How to?

This post details how to extend Coded UI Test support to third-party Windows Forms controls by implementing Microsoft Active Accessibility (MSAA) on the control, overriding accessibility methods for basic record and playback, and implementing a custom PropertyProvider to enable rich property validation (e.g., BackColor, ForeColor) via the Coded UI Test Builder. It also covers creating specialized classes for custom controls to enable code generation for these controls in recorded tests. The post provides detailed code examples for each level of implementation.
