After languages B, C, C++, C#, comes language D – but since the name D was already taken by this other guy, Microsoft  codenamed it Oslo, and then finally “M” (not to confused with the old M language; worth noting here languages E, F, & G).
M for … Microsoft? it’s M for Modeling Language.

The language is supposedly very rich in the meta data one can add. Some say it is briefer even than C# (which is generally very efficient), and results in better quality code given the ability to compare the program’s actual output vs the “intention” coded in the meta data.

But I’m still reading about it. More details later. For now, here’s a link to the first public Microsoft bulletin about this language:
