- 12. • System.Diagnostics.Contracts • CodeContracts introduce a way to specify contractual information that is not represented by a method or type’s signature alone • Scenarios for using contracts include: • Perform static bug finding, which enables some bugs to be found without executing the code • Create guidance for automated testing tools to enhance test coverage • Create a standard notation for code behavior, which provides more information for documentation Design By Contract

- 17. • Dynamic Type • Operations that contain expressions of type dynamic are not resolved or type ch`ecked by the compiler. The compiler packages together information about the operation, and that information is later used to evaluate the operation at run time • Optional and Named Parameters • Named arguments enable you to specify an argument for a particular parameter by associating the argument with the parameter's name rather than with the parameter's position in the parameter list. • Optional arguments enable you to omit arguments for some parameters. Both techniques can be used with methods, indexers, constructors, and delegates. C#
