With the .NET Core becoming open source, now is the perfect time to create new languages that span the breadth and depth of the Common Language Runtime. In this talk, I will discuss: - EBNF syntax in a nutshell, and how you can use it to generate your own language, - How to create your own interpreter in ANTLR 4 and have it up and running in C#, - How to parse your custom language into a syntax tree, - How to implement the differences between virtual machines, interpreters, and compilers It will also focus on practical compiler examples in C# rather than burden you with compiler theory. If you're the type of developer that loves learning new languages, then this is definitely the talk you need to attend!
