This document provides harmful advice to .NET developers, including not washing hands or face, not getting haircuts, and using only Visual Studio, SQL Server, and Entity Framework for projects. It recommends over-engineering projects with many unnecessary layers, entities, and namespaces. It advises against useful tools and practices like automapping, conventions, dependency injection, NoSQL databases, and command line usage. The intent is to humorously highlight approaches that would negatively impact productivity and maintenance.
