Microsoft Visual Studio is an integrated development environment (IDE) from Microsoft. It can be used to develop console and graphical user interface applications along with Windows Forms applications, web sites, web applications, and web services in both native code together with managed code for all platforms supported by Microsoft Windows, Windows Mobile, Windows CE, .NET Framework, .NET Compact Framework and Microsoft Silverlight.
Visual Studio includes a code editor supporting IntelliSense as well as code refactoring. The integrated debugger works both as a source-level debugger and a machine-level debugger. Other built-in tools include a forms designer for building GUI applications, web designer, class designer, and database schema designer. It accepts plug-ins that enhance the functionality at almost every level—including adding support for source-control systems (like Subversion and Visual SourceSafe) and adding new toolsets like editors and visual designers for domain-specific languages or toolsets for other aspects of the software development lifecycle (like the Team Foundation Server client: Team Explorer).
Microsoft provides "Express" editions of its Visual Studio 2010 components Visual Basic, Visual C#, Visual C++, and Visual Web Developer at no cost. Visual Studio 2010, 2008 and 2005 Professional Editions, along with language-specific versions (Visual Basic, C++, C#, J#) of Visual Studio 2005 are available for free to students as downloads via Microsoft's DreamSpark program. The 90-day trial version of Visual Studio can be downloaded by the general public at no cost.

Visual Studio 2010 On April 12, 2010, Microsoft released Visual Studio 2010, codenamed Dev10, and .NET Framework 4.
Visual Studio 2010 features a new UI developed using WPFThe Visual Studio 2010 IDE has been redesigned which, according to Microsoft, clears the UI organization and "reduces clutter and complexity." The new IDE better supports multiple document windows and floating tool windows, while offering better multi-monitor support. The IDE shell has been rewritten using the Windows Presentation Foundation (WPF), whereas the internals have been redesigned using Managed Extensibility Framework (MEF) that offers more extensibility points than previous versions of the IDE that enabled add-ins to modify the behavior of the IDE. However, the ability to customize the layout, content and position of toolbars and menus is limited in Visual Studio 2010.
The new multi-paradigm programming language ML-variant F# forms part of Visual Studio 2010; as do M, the textual modeling language, and Quadrant, the visual model designer, which are a part of the Oslo initiative.
Visual Studio 2010 comes with .NET Framework 4 and supports developing applications targeting Windows 7.It supports IBM DB2 and Oracle databases, in addition to Microsoft SQL Server. It has integrated support for developing Microsoft Silverlight applications, including an interactive designer. Visual Studio 2010 offers several tools to make parallel programming simpler: in addition to the Parallel Extensions for the .NET Framework and the Parallel Patterns Library for native code, Visual Studio 2010 includes tools for debugging parallel applications. The new tools allow the visualization of parallel Tasks and their runtime stacks. Tools for profiling parallel applications can be used for visualization of thread wait-times and thread migrations across processor cores.Intel and Microsoft have jointly pledged support for a new Concurrency Runtime in Visual Studio 2010 and Intel has launched parallelism support in Parallel Studio as an add-on for Visual Studio.
The Visual Studio 2010 code editor now highlights references; whenever a symbol is selected, all other usages of the symbol are highlighted. It also offers a Quick Search feature to incrementally search across all symbols in C++, C# and VB.NET projects. Quick Search supports substring matches and camelCase searches. The Call Hierarchy feature allows the developer to see all the methods that are called from a current method as well as the methods that call the current one.IntelliSense in Visual Studio supports a consume-first mode which developers can opt into. In this mode, IntelliSense will not auto-complete identifiers; this allows the developer to use undefined identifiers (like variable or method names) and define those later. Visual Studio 2010 can also help in this by automatically defining them, if it can infer their types from usage.
Visual Studio 2010 features a new Help System replacing the MSDN Library viewer. The Help System is no longer based on Microsoft Help 2 and does not use Microsoft Document Explorer. Dynamic help containing links to related help topics based on where the developer was in the IDE has been removed in the shipping product, but can be added back using a download from Microsoft.
Visual Studio Ultimate 2010 Visual Studio Ultimate 2010 (formerly Team System 2010), codenamed Rosario. It includes new modeling tools, such as the Architecture Explorer, which graphically displays projects and classes and the relationships between them. It supports UML activity diagram, component diagram, (logical) class diagram, sequence diagram, and use case diagram. Visual Studio Ultimate 2010 also includes Test Impact Analysis which provides hints on which test cases are impacted by modifications to the source code, without actually running the test cases. This speeds up testing by avoiding running unneeded test cases.
Visual Studio Ultimate 2010 also includes a Historical Debugger for managed code called IntelliTrace. Unlike the current debugger, that records only the currently-active stack, IntelliTrace records all events like prior function calls, method parameters, events, exceptions etc. This allows the code execution to be rewound in case a breakpoint wasn't set where the error occurred.IntelliTrace will cause the application to run slower than the current debugger, and will use more memory as additional data needs to be recorded. Microsoft allows configuration of how much data should be recorded, in effect allowing developers to balance speed of execution and resource usage. The Lab Management component of Visual Studio Ultimate 2010 uses virtualization to create a similar execution environment for testers and developers. The virtual machines are tagged with checkpoints which can later be investigated for issues, as well as to reproduce the issue. Visual Studio Ultimate 2010 also includes the capability to record test runs that capture the specific state of the operating environment as well as the precise steps used to run the test. These steps can then be played back to reproduce issues.
