Can we have a complete documented language reference like the one that used to be part of the VS installation? It stopped at C#5. I appreciate language versions not tied to the VS release cycle, and that there is a *draft* of C#6, but could you not maintain an up to date language reference on the git hub repo to the same quality of the C# 5 version? Dropping the maintenance of a high-quality precise and thorough language reference document is a disconcerting fall in standards. The C#7 features are terrific; I want to be able to read about them in a single reference document and not have to trawl through lots of web pages to piece them together.
Excellent stuff as usual. Apart from looking at part one, I haven't looked at MEF at all and I was able to follow it no problem. If the problem is lack of background, then there are better places to get the in depth theory of why MEF is useful than here.
For me, it's perfect pace and content. Loving it.
