Spec Sharp

Spec Sharp is a historical programming language created in 2004. Spec# is a programming language with specification language features that extends the capabilities of the C# programming language with Eiffel-like contracts, including object invariants, preconditions and postconditions. Like ESC/Java, it includes a static checking tool based on a theorem prover that is able to statically verify many of these invariants. It also includes a variety of other minor extensions to the language, such as non-null reference types. Read more on Wikipedia...
