working as the only senior dev on a manufacturing tool that has been around forever. the ui layer is all custom controls and heavy data binding that breaks every time we add a new report. spent weeks watching scattered youtube videos but they never cover how to untangle years of accumulated mess without breaking production. tried building a small test project on the side to practice better patterns but keep running into the same binding and command issues.

really tired of piecing together random tutorials that assume everything starts clean. looking for something structured that walks through real world refactoring step by step.

has anyone found a WPF course that actually helped clean up a tangled legacy desktop application?
