New features and fixed issues in Visual Studio 2012 Update 1

New features

Microsoft SharePoint development
To improve quality, scalability and agility, additional application life cycle management (ALM) capabilities are added to SharePoint development, such as load testing and coded UI testing support.
  • IntelliTrace collection for SharePoint applications (
    This feature can change and access data, and provides a rich analysis experience for SharePoint applications.
  • The ability to create coded UI testing for SharePoint 2010 applications (
    These tests simulate user interaction and validate the functionality and behavior of an application’s UI.
  • Web performance testing (
    Web performance testing on SharePoint solutions can verify performance. The tests can be recorded, and then run and analyzed against the SharePoint solutions.
  • Load testing support for SharePoint applications (
    This feature enables stress testing of a SharePoint application. It can simulate high user loads, different network topologies, and some other conditions.
  • SharePoint emulators provide the basic behavior of the SharePoint 2010 server object model (
    SharePoint emulators provide a Microsoft Fakes framework. The framework enables developers to write unit tests that stub-out the required SharePoint dependencies.
Windows development
  • Enable Windows XP targeting for building Visual C++ applications (
    You can target Windows XP by using Visual Studio’s C++ multi-targeting feature. This feature enables you to use the Microsoft Visual Studio 2010 compiler in Visual Studio 2012.
  • JavaScript memory analysis tool (
    The JavaScript memory analysis tool helps you understand memory usage and find memory leaks in your Windows Store app that is built for Windows by using JavaScript.
  • Memory profiling for JavaScript applications (
    The profiler can help you find the performance bottlenecks in your JavaScript functions and algorithms.
  • Windows Store C++ unit testing improvements (
    You can add references to C++ Windows Store executables and custom Extensible Application Markup Language (XAML) controls in your C++ Windows Store unit test libraries.
  • Support for debugging the ARM-based native dump file (
    You can debug dump files of native C++ apps from ARM-based computers and devices with the same dump-debugging functionality that you are accustomed to on x86-based or x64-based computers.
  • Support for debugging mixed managed and native Windows Store apps
Agile teams
You can use Web Access for your Agile plan easily, and new Kanban support is available alongside existing Scrum support.
New test features in Microsoft Test Manager (MTM)
  • Code coverage for web applications in MTM (
    Testers can now know how much of the application code is being covered by test cases executed within MTM, and developers can now know whether their code is being accessed by the application and is a valid test case.
  • Cross browser testing support for coded UI test (
    You can use coded UI tests help automate browser based applications that are built on Internet Explorer, Firefox and Chrome.
  • Create an image action log from exploratory tests (
  • Populate test suites using hierarchical queries in MTM (
  • Directly edit test case properties from the Test Runner of MTM (
  • Data collectors populate Trait information for Visual Studio unit test grouping (
    You can now organize and filter the test runs based on several conditions in Test Explorer. Traits is a new concept, a common denominator for several underlying terms: Test Category, Test Property, Priority, and Owner.
  • The ability to pause and resume manual test sessions in MTM (
  • Automatic updates for MTM and Microsoft Feedback Client (
  • Usability improvements for coded UI testing
  • No need to manually install SQL Server Express for load testing (By default, use LocalDB)
  • Use command-line functionality to deep copy test plans to better support release management
  • Publish test results to Team Foundation Server (TFS) from the command line
New features in Team Foundation Server
