In a recent post (1) a nice introduction into Microsoft Solver Foundation is provided. Unfortunately Solver Foundation has been discontinued a while ago; the last version was 3.1 in 2012.
The author is from Ukraine. I think there was a fellow countryman who was once very active in the Optimization arena with his Python tools. Dmitrey Kroshko had a fairly active website (openopt.org). I have no idea what happened to Dmitrey or OpenOpt.
