49. How do developers know they are writing code that can be maintained and understood in the future? Visual Studio 2008 Team System integrates sophisticated code metrics that enable developers to clearly understand how maintainable and complex the code they are building is; This understanding is gathered from the following metrics Cyclometic complexity Maintainability Index Inheritance Depth Class Coupling Lines of code Visual Studio 2008 Team System integrates sophisticated code metrics that enable developers to clearly understand how maintainable and complex the code they are building is; This understanding is gathered from the following metrics Cyclometic complexity Maintainability Index Inheritance Depth Class Coupling Lines of code The Challenge The Solution
