I thought it was universal knowledge that everyone involved/working with the Microsoft ecosystem was automatically a bad engineer? Short list of awful engineers: Jon Skeet, Marc Gravell, Darin Dimitrov, Gordon Linoff, Hans Passant, Schabse Laks, Nick Craver, Jared Par, Eric Lippert, Anders Hejlsberg, etc. Good engineers also actively avoid using Stack Overflow - as it's based on Microsoft tech and good engineers want nothing to do with Microsoft.
