Core Coding Experience in Managed Languages

Visual Studio 2010 is an exciting release in managed languages and tools.  Visual C# and Visual Basic languages continue to evolve towards feature parity, strive to simplify programming and deployment with the Microsoft Office APIs, and allow easy interop to dynamic languages.  Visual F# is a new programming language which combines functional, object-oriented and explorative programming to provide a succinct, expressive and scalable language for .NET.  In the tools space, Visual Studio 2010 offers greater support for Test-Driven Development, where tests are written before product code as an iterative approach to software design.

Office Development in Visual Studio 2010

Visual Studio 2010 comes with improved Office Development functionality. You can now deploy multiple Office Solutions in one package which will appear as a single entry in the Add/Remove Programs in Windows XP or Programs and Features in Windows Vista. Visual Studio 2010 now also allows you to perform additional actions after the Office solution installation is complete such as copy documents or workbooks to the end user computer, create extra registry keys, or modify a configuration file.

Multi-targeting

The multi-targeting feature of Visual Studio lets you specify the version of the .NET Framework, or its profile, that is required for your application. The key benefit of multi-targeting is that you can use the current version of Visual Studio to create and develop projects that target earlier versions of the .NET Framework. For example, you can continue to develop projects that were created in Visual Studio 2008 without adding new .NET Framework dependencies.

Parallel Computing

The Parallel Extensions to the .NET Framework 4 and the Concurrency Runtime for Visual C++ 2010 enable developers to leverage parallel computing. By using these frameworks, developers can write parallel applications that will scale efficiently as the numbers of cores and processors increase. By avoiding the complexities of thread-focused programming models, the new parallel libraries simplify the production of parallel code and enable developers to more easily take advantage of parallel hardware. Visual Studio 2010 Beta 1 also provides new debugging and profiling tools to help developers understand and verify the behavior of their parallel applications.

Workflow Foundation

Workflow Foundation (WF) provides significant enhancements in this release such as explicit data model and fully declarative experience for authoring activities, a new Flowchart modeling style, deeper integration with Windows Communication Foundation (WCF) and high performance runtime engine.
