As part of it, Microsoft released a new language: U-SQL.
For a developer point of view, U-SQL is a new SQL language with expressions written in C#.
My name’s Matthieu Mezil and I’m a developer on the U-SQL compiler team.
You can find more details on the motivation for U-SQL, some of our inspiration, and design philosophy behind the language, and a few examples of the major aspects of the language on Michael post
As one of Roslyn first fans, I will write about coding and mainly meta-programming in this blog, including the way U-SQL compiler uses Roslyn for the C# part of the language.
