WPF and MVVM fan, I practice C # in all its forms from the beginning of the NET Framework without mentioning C ++ / MFC and other software packages such as databases, ASP, WCF, Web & Windows services, Application, and now Core and UWP.
In my wasted hours, I am guilty of having fathered C.B.R. and its cousins C.B.R. for WinRT and UWP on the Windows store.
But apart from that, I am a great handyman ... the house, a rocket stove to heat the jacuzzi and the last one: a wood oven for pizza, bread, and everything that goes inside
