Contract.Ensures Method (Boolean)
Specifies a postcondition contract for the enclosing method or property.
Assembly: mscorlib (in mscorlib.dll)
The condition parameter specifies a postcondition that is expected to be true when the enclosing method or property returns normally.
This method call must be at the beginning of a method or property, before any other code.
You must use the binary rewriter (available at Code Contracts on the MSDN DevLabs Web site) for run-time enforcement of this postcondition.
