【SpeC#】－C#的又一同胞兄弟

        前天偶逛微软的http://research.microsoft.com/,发现.NET中又添新丁了，
不过尚处实验室中。

Overview

The Spec# programming system is a new attempt at a more cost effective way to develop and maintain high-quality software.  Spec# is pronounced "Spec sharp" and can be written (and searched for) as the "specsharp" or "Spec# programming system".  The Spec# system consists of:

• The Spec# programming language.  Spec# is an extension of the object-oriented language C#.  It extends the type system to include non-null types and checked exceptions.  It provides method contracts in the form of pre- and postconditions as well as object invariants.
• The Spec# compiler.  Integrated into the Microsoft Visual Studio development environment for the .NET platform, the compiler statically enforces non-null types, emits run-time checks for method contracts and invariants, and records the contracts as metadata for consumption by downstream tools.
• The Spec# static program verifier.  This component (codenamed Boogie) generates logical verification conditions from a Spec# program.  Internally, it uses an automatic theorem prover that analyzes the verification conditions to prove the correctness of the program or find errors in it.
