Abstract	CodeContracts allow specifying contracts (preconditions, postconditions and object invariants) in a language agnostic form. Contracts are expressed as calls to static methods of the homonymous class included in .NET 4.0. They are serialized and persisted as bytecode, achieving language agnosticism. Runtime checking is performed via bytecode rewriting. The static checker, Clousot, directly analyzes the bytecode to validate the user-provided contracts as well as the absence of common runtime errors. Clousot is based on abstract interpretation, and as such it can presents a higher level of automatism (e.g. for the inference of loop invariants, or postconditions) with respect to similar tools. Also, it scales up to large codebases thanks to the use of new numerical abstract domains and adaptive techniques (which I will sketch in the talk).
