Remove code correctly

Summary

The transcript discusses the strategic use of the obsolete attribute in C#, highlighting the importance of purposeful deprecation. Developers often misuse the obsolete marker, creating warning noise that teams eventually ignore, leading to code stagnation. The key recommendation is to only use the obsolete attribute when there is a definitive plan for method removal, a clear replacement, and a specific deprecation schedule. By being intentional and selective with deprecation warnings, developers can maintain cleaner, more meaningful codebases.
