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. The ''code contracts'' API in the .NET Framework 4.0 has evolved with Spec#. Microsoft Research developed both Spec# and C#; in turn, Spec# serves as the foundation of the Sing# programming language, which Microsoft Research also developed. ==Features== :''See also: Spec# in C Sharp syntax.'' Spec# extends the core C# programming language with features such as: * Non-nullable types * Structures for code contract like ''preconditions'' and ''postconditions''. * Checked exceptions similar to those in Java. * Convenient syntax 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Spec Sharp」の詳細全文を読む スポンサード リンク
