Using Expression Trees for internal DSLs in C# 3.5

Ian Cooper continues his series of 3 talks on domain specific languages DSL. He talks about fluent interfaces and how they can be created using extension methods. Fluent interfaces provide a ‘discoverable’ API which is easier to read...

Ian then gives a demonstration of how fluent interfaces can be created and how discoverable the API really is.

Ian then introduces Closures. Closures are basically a generic name for treating a function as data. It is generally done using a lambda expression. Ian explains how this can be done within DSLs and where it is useful. He also gives a demonstration of it being used. Ian finishes with an introduction to Parse Trees and how all of these features can be used in real world DSLs.
