It is used to develop computer programs , as well as websites , web apps , web services and mobile apps. It can produce both native code and managed code. Visual Studio includes a code editor supporting IntelliSense the code completion component 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 code profiler , designer for building GUI applications, web designer , class designer, and database schema designer.
It accepts plug-ins that expand the functionality at almost every level—including adding support for source control systems like Subversion and Git 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 Azure DevOps client: Team Explorer. Visual Studio supports 36 different programming languages and allows the code editor and debugger to support to varying degrees nearly any programming language, provided a language-specific service exists.
Support for other languages such as Python , [9] Ruby , Node. Java and J were supported in the past. The most basic edition of Visual Studio, the Community edition, is available free of charge. As of 8 November [update] the current production-ready Visual Studio version is , with older versions such as and on Extended Support, and and on Mainstream Support.
Visual Studio does not support any programming language, solution or tool intrinsically; instead, it allows the plugging of functionality coded as a VSPackage. When installed, the functionality is available as a Service. In addition, the IDE is also responsible for coordinating and enabling communication between services. A language service defines various interfaces which the VSPackage implementation can implement to add support for various functionalities. Language services are implemented on a per-language basis.
The implementations can reuse code from the parser or the compiler for the language. Visual Studio does not include any source control support built in but it defines two alternative ways for source control systems to integrate with the IDE. Visual Studio. Visual Studio supports running multiple instances of the environment each with its own set of VSPackages.
The instances use different registry hives see MSDN 's definition of the term "registry hive " in the sense used here to store their configuration state and are differentiated by their AppId Application ID. The instances are launched by an AppId-specific. The various product editions of Visual Studio are created using the different AppIds.
Consequently, one can install the Express editions side-by-side with other editions, unlike the other editions which update the same installation. The professional edition includes a superset of the VSPackages in the standard edition, and the team suite includes a superset of the VSPackages in both other editions.
Visual Studio like any other IDE includes a code editor that supports syntax highlighting and code completion using IntelliSense for variables , functions , methods , loops , and LINQ queries. In Visual Studio onwards, it can be made temporarily semi-transparent to see the code obstructed by it. The Visual Studio Code Editor also supports setting bookmarks in code for quick navigation. Other navigational aids include collapsing code blocks and incremental search , in addition to normal text search and regex search.
A management tool for code snippets is built in as well. These tools are surfaced as floating windows which can be set to automatically hide when unused or docked to the side of the screen.
The Visual Studio code editor also supports code refactoring including parameter reordering, variable and method renaming, interface extraction, and encapsulation of class members inside properties, among others. Visual Studio includes a debugger that works both as a source-level debugger and as a machine-level debugger. It works with both managed code as well as native code and can be used for debugging applications written in any language supported by Visual Studio.
In addition, it can also attach to running processes, monitor, and debug those processes. If source code is not available, it can show the disassembly. The Visual Studio debugger can also create memory dumps as well as load them later for debugging. The debugger can be configured to be launched when an application running outside the Visual Studio environment crashes.
The Visual Studio Debugger allows setting breakpoints which allow execution to be stopped temporarily at a certain position and watches which monitor the values of variables as the execution progresses. Code can be stepped over , i. When debugging, if the mouse pointer hovers over any variable, its current value is displayed in a tooltip "data tooltips" , where it can also be modified if desired.
During coding, the Visual Studio debugger lets certain functions be invoked manually from the Immediate tool window. The parameters to the method are supplied at the Immediate window. Visual Studio includes a host of visual designers to aid in the development of applications. These tools include:. Visual Studio allows developers to write extensions for Visual Studio to extend its capabilities.
These extensions "plug into" Visual Studio and extend its functionality. Extensions come in the form of macros , add-ins , and packages. Macros represent repeatable tasks and actions that developers can record programmatically for saving, replaying, and distributing. Macros, however, cannot implement new commands or create tool windows. They are written using Visual Basic and are not compiled.
Add-Ins can be used to implement new functionality and can add new tool windows. They can create designers and other tools, as well as integrate other programming languages. However, the managed API isn't as comprehensive as the unmanaged one.
Express Editions do not support hosting extensions. On top of that, other packages can be added to customize the installation.
The Isolated mode of the shell creates a new AppId where the packages are installed. These are to be started with a different executable. It is aimed for development of custom development environments, either for a specific language or a specific scenario.
It serves as the central location for posting information about extensions to Visual Studio. Community developers as well as commercial developers can upload information about their extensions to Visual Studio. NET through Visual Studio Users of the site can rate and review the extensions to help assess the quality of extensions being posted. An extension is stored in a VSIX file. One of the main advantages of these extensions is that they do not require Administrator rights to be installed. RSS feeds to notify users on updates to the site and tagging features are also planned.
The Community edition was announced on November 12, , as a new free version, with similar functionality to Visual Studio Professional. Prior to this date, the only free editions of Visual Studio were the feature-limited Express variants.
Unlike the Express variants, Visual Studio Community supports multiple languages, and provides support for extensions. Individual developers have no restrictions on their use of the Community edition. The following uses also allow unlimited usage: contributing to Open Source projects, academic research, in a classroom learning environment and for developing and testing device drivers for the Windows operating system. All other use by an organization depends on whether you are classified as an Enterprise more than employees or more than 1 million USD in annual revenue, per Microsoft.
As of Visual Studio , the Professional edition is the entry level commercial edition of Visual Studio. Previously, a more feature restricted Standard edition was available. Windows Mobile development support was included in Visual Studio Standard, however, with Visual Studio , it is only available in Professional and higher editions.
Windows Phone 7 development support was added to all editions in Visual Studio Development for Windows Mobile is no longer supported in Visual Studio It is superseded by Windows Phone 7. In addition to the features provided by the Professional edition, the Enterprise edition provides a new set of software development, database development, collaboration, metrics, architecture, testing and reporting tools. The first version of Visual Studio was Visual Studio Microsoft first released Visual Studio codenamed Boston , [] for the city of the same name , thus beginning the VS codenames related to places [] in , bundling many of its programming tools together for the first time.
Visual Studio 97 was an attempt at using the same development environment for multiple languages. The next version, version 6. The v6 edition of Microsoft was the core environment for the next four releases to provide programmers with an integrated look-alike platform.
This led Microsoft to transition the development on the platform independent. NET Framework. Visual Studio 6. Microsoft released Visual Studio. NET VS. The biggest change was the introduction of a managed code development environment using the. Programs developed using. When a CIL application executes, it is compiled while being executed into the appropriate machine language for the platform it is being executed on, thereby making code portable across several platforms.
Programs compiled into CIL can be executed only on platforms which have an implementation of Common Language Infrastructure. Microsoft introduced C C-sharp , a new programming language, that targets. Visual J programs use Java's language-syntax. Visual Basic changed drastically to fit the new framework, and the new version was called Visual Basic.
NET and Web Services and, with an add-in, portable devices using the. NET Compact Framework. The internal version number of Visual Studio.
