5. Remote Development Features of RDp Remote project/files. Remote editor with content assist Outline View Remote Search Call Hierarchy and other analysis Remote build Build error feedback

6. Debugging Power Applications Variables view shows changes between steps Debug view shows the process, its threads, and their stacks. You can look back up the stack just by choosing a stack frame. Integrated editor shows the current line highlighted Outline views makes source navigation easy

13. Work Items Capture Traceability and Effort Predefined, custom and personal queries Subscribe to work items you're interested in Query results Integrated discussion threads & chat sessions Understands and persists work items' relationship to SCM and build artifacts SCRUM built in artifact types

15. Web-based Taskboards Increase Team Visibility See the work in progress or completed Drag and drop work items to change their state. Show stories linked to a set of associated tasks and their status

16. Plan Risk Assessment Color codes high risk tasks for quick identification and action Automatically calculates probability of task fitting into the schedule More detailed developer estimation.. low, nominal, high

17. Web Based Project and Portfolio Dashboards

18. Builds – Extensible Continuous Integration Run personal builds to check your changes before sharing them with the team Create build servers Identify work items and change sets that went into the build Historical view of the build queue with status Even reconstruct a work space from a failed build!

21. Promote Application Artifacts Promote objects from integration to test and from test to packaging using a controlled, enforceable process Integration Stream Testing Stream Integration Build Definition Packaging Stream Testing Build Definition Packaging Build Definition Integration Built Libraries Testing Built Libraries Packaging Built Libraries Dev WS Dev WS Team Roles and Permissions Work Items Source Control Build
