New in Visual Studio 2010 Rosario

• Codenamed ‘Rosario’.

• Aims to become a tool for everyone involved in Application Lifecycle Management (ALM) – from architects to developers, from project managers to testers. Not just for developers.

• Unified Development and Database product editions.
• Architecture Explorer – to discover and identify existing code assets and architecture in number of ways including graphs, stacked diagrams and dependency matrices.

Design & Architecture

• Ability to create and share various types of diagrams like use case, activity and sequence diagrams.

• Modeling tools that are tightly integrated with code and thus helps in keeping model and code in sync.

• Architectural Validations – Ways to put constraints on code using models and doing validations at the time of check-ins and builds.

• Architecture Layer Diagram – One of the most useful and simple tool getting introduced. It allows representing your application architecture in form of layers and showing dependencies between them. It also allows to map physical components like classes, namespaces etc. to map to these layers. After all mappings you can validate whether the code meets the expected mappings and constraints.

• Microsoft joins OMG and UML gets introduced in Visual Studio 2010.

• Support for UML 2.1.1 – 5 out of 13 diagrams – use case, component, activity, class and sequence diagrams.

• Ability to keep all the UML diagrams in sync so that a change in one automatically reflects on others.

• UML design tool is developed using DSL toolkit.

• Will be interoperable with Visio 1.1 templates.

• Supports Top to bottom design approach.

• Supports Bottom to top design approach – reverse engineer. Filter based on namespaces, number of level deep.

• Model Explorer – Similar to Solution Explorer, this allows you to explore all the models you have created which includes objects created as part of various UML diagrams – logical view.

• Ability to create a Sequence Diagram from existing source, simply by right clicking in the VS code editor and selecting “Generate Sequence Diagram…”

• Parallel Programming: To better utilize power of multi-processor and multi-core machines, .NET 4.0 will add support for parallel programming using PLINQ, Task Parallel Library and Coordination Data Structures. The debugger has been enhanced to identify concurrency issues. Two new features added are MultiStack and a Task List views. Introduction of concurrency analysis report for performance analysis of applications.
• Test Impact View – Identify and run only the tests impacted by a code.

Quality/ Testing

• Eliminating ‘no-repro’ bug  i.e. bugs that can’t be reproduced by providing tools for better collection of test data.
• The Microsoft Test Runner Tool – a standalone tool that a tester uses to guide them through a series of steps to complete a test case. During the test run, this tool can take snapshot of test environment, application screenshots and even capture full video for assisting in reproducing bugs.
• Enhanced version control capabilities including gated check-in, branch visualization and build workflow.

Source Code Management

• Ability to perform constraints check on code during check-in based on Architecture Layer Diagram.
• Integration with Project Server for enterprise wide project management and new features for Agile project scheduling with Excel.
