Advanced code clone detection to find redundant code and "Code Metrics" to measure maintainability. General 2012 Improvements (All Editions)
Visual Studio 2012 introduced several platform-wide enhancements available in the ISO:
Includes IntelliTrace for "historical debugging" (recording the execution history to find bugs faster), as well as Continuous Stress-Testing and Lab Management.
As the "Ultimate" edition, it focused on the entire application lifecycle management (ALM) process:
Projects and key IDE components load asynchronously, allowing you to start coding before the entire solution is fully loaded.
Tools for creating Layer Diagrams, UML diagrams (Class, Sequence, Use Case), and Architecture Explorer to visualize complex codebases.
