Introduction to VSTS Introduction to Visual Studio 2008 Development Edition Understanding code complexity using Code Metrics

Visual Studio Team System

Development Edition Features Unit testing with code coverage Static Code Analysis Code Profiling Code Metrics

Integrated Unit Testing Integrated Static Code analysis Security Errors Localization problems Memory issues … Integrated Profiler Performance problems Memory problems Potential Sql Injection attack Object not Disposed Localization Issue Improving Code Quality

Who allocates the most Objects Who allocates the most memory Who is called the most? Who runs for the longest What do you have the most of? What is taking up the most memory Improving Quality: Profiler

Performance Report Summary

Gives a snapshot of software health Understand your code complexity Quickly compare code to find potential trouble spots Reduce risk & improve maintainability Understand complexity of inherited code Code metrics
