Keyboard Schemes in Visual Studio

Some extensions also offer keyboard schemes:

The following are popular Visual Studio shortcuts:

Shortcut (All Profiles) Command Description
Ctrl+T Go To All Navigate to any file, type, member, or symbol declaration
F12 (also Ctrl+Click) Go To Definition Navigate to where a symbol is defined
Ctrl+F12 Go To Implementation Navigate from a base type or member to its various implementations
Shift+F12 Find All References See all symbol or literal references
Alt+Home Go To Base Navigate up the inheritance chain
Ctrl+. (also Alt+Enter in C# Profile) Quick Actions and Refactorings See what code fixes, code generation actions, refactorings, or other quick actions are available at your cursor position or code selection
Ctrl+D Duplicate line Duplicates the line of code that the cursor is in
Shift+Alt++/- Expand/Contract selection Expands or contracts the current selection in the editor
Shift + Alt + . Insert Next Matching Caret Adds a selection and caret at the next location that matches the current selection
Ctrl+Q Search Search all Visual Studio settings
F5 Start Debugging Start debugging your application
Ctrl+F5 Run without Debug Run your application locally without debugging
Ctrl+K,D (Default Profile) or Ctrl+E,D (C# Profile) Format Document Cleans up formatting violations in your file based on your newline, spacing, and indentation settings
Ctrl+\,Ctrl+E (Default Profile) or Ctrl+W,E (C# Profile) View Error List See all errors in your document, project, or solution
Alt + PgUp/PgDn Go to Next/Previous Issue Jump to the previous/next error, warning, suggestion in your document
Ctrl+K,/ Toggle single line comment/uncomment This command adds or removes a single line comment depending on whether your selection is already commented
Ctrl+Shift+/ Toggle block comment/uncomment This command adds or removes block comments depending on what you've selected


Some extensions unbind the default Visual Studio keybindings. You can restore your keybindings to their defaults by going to Tools > Import and Export Settings > Reset all settings or Tools > Options > Keyboard > Reset.

For more information about keyboard shortcuts and commands, see Productivity shortcuts. Or, see Keyboard shortcuts in Visual Studio for a comprehensive list along with a downloadable cheat sheet.

Visual Studio has a feature called Go To All that you can use to quickly jump to any file, type, member, or symbol declaration. To open it from the menu bar, select Edit > Go To > Go To All. Or, you can open it by using the Ctrl+T keyboard shortcut.

A small window is displayed at the top right of your code editor.

You can use this feature to perform the following actions:

  • Change the location of its search bar or turn off the live navigation preview by using the gear icon.
  • Filter results by using syntax such as t mytype.
  • Scope your search to just the current document.
  • Camel case matching is supported.

For more information about Go To All, see Find code by using Go To commands.

Enforce code style rules

You can use an EditorConfig file to codify coding conventions and have them travel with your source.

Code style enforcement in Visual Studio

  • Add a default or .NET-style EditorConfig file to your project by choosing Add > New Item from the Add context menu fly-out in Solution Explorer. Then, in the Add New Item dialog box, search for "editorconfig". Select either of the editorconfig File item templates and then choose Add.

  • Automatically create an .editorconfig file based on your code style settings in Tools > Options > Text Editor > C# > Code Style.

  • The code inference feature of IntelliCode for Visual Studio infers your code styles from existing code. It then creates a non-empty EditorConfig file with your code-style preferences already defined.

  • Configure the severity level of a code style rule directly through the editor. If you currently do not have an .editorconfig file, Visual Studio generates one for you. Place your cursor on the error, warning, or suggestion and type Ctrl+. to open the Quick Actions and Refactorings menu. Select Configure or Suppress issues. Then select the rule and choose the severity level you would like to configure for that rule. This will update your existing EditorConfig with the rule’s new severity.

Configure the severity level of a code style rule directly in the editor

Check out the .NET code-style rule options documentation, which also includes an example of a complete EditorConfig file.

Code Cleanup

Visual Studio provides on-demand formatting of your code file, including code style preferences, through the Code Cleanup feature. To run Code Cleanup, select the broom icon at the bottom of the editor or press Ctrl+K, Ctrl+E.

Screenshot of the Code Cleanup button and options.

You can also run code cleanup across your entire project or solution. Right-click the project or solution name in Solution Explorer, select Analyze and Code Cleanup, and then select Run Code Cleanup.

In addition to formatting your file for spaces, indents, et cetera, Code Cleanup also applies selected code styles. Your preferences for each code style are read from the EditorConfig file, if you have one for the project, or from the code style settings in the Options dialog box.

Refactorings and code fixes

Visual Studio comes with numerous refactorings, code generation actions, and code fixes. Red squiggles represent errors, green squiggles represent warnings, and three gray dots represent code suggestions. You can access code fixes by selecting the light bulb or screwdriver icon, or by pressing Ctrl+. or Alt+Enter. Each fix comes with a preview window that shows a live code diff of how the fix works.

Popular quick fixes and refactorings include:

  • Rename
  • Extract Method
  • Change Method Signature
  • Generate Constructor
  • Generate Method
  • Move Type to File
  • Add Null-Check
  • Add Parameter
  • Remove Unnecessary Usings
  • Foreach Loop to LINQ Query or to LINQ method
  • Pull Members Up

For more information, see code generation features.

You can install .NET analyzers to flag code issues. Or, write your own refactoring or code fix with Roslyn analyzers.

Several community members have written free extensions that add additional code inspections:

Find Usages, Go To Implementation, and Navigate To Decompiled Assemblies

Visual Studio has many features to help you search and navigate your code.

Feature Shortcut Details/Improvements
Find All References Shift+F12 Results are colorized and can be grouped by project, definition, and reference type, such as read or write. You can also "lock" results.
Go To Implementation Ctrl+F12 You can use Go To Definition on the override keyword to navigate to the overridden member
Go To Definition F12 or Ctrl+Click Press Ctrl while clicking to navigate to definition
Peek Definition Alt+F12 Inline view of a definition
Structure Visualizer Gray, dotted-lines between braces Hover to see your code structure
Navigation to decompiled assemblies F12 or Ctrl+Click Navigate to external source (decompiled with ILSpy) by enabling the feature: Tools > Options > Text Editor > C# > Advanced > Enable navigation to decompiled sources.

Go To All and Find All References

Improved IntelliSense

Use IntelliCode for Visual Studio to get context-aware code completions instead of just an alphabetical list. You can also train a custom IntelliSense model based on your own domain-specific libraries.

Unit testing

We've made numerous improvements to the testing experience. You can test with the MSTest (MSTest v1 or MSTest v2), NUnit, and XUnit test frameworks.

  • Test Explorer test discovery is fast.

  • Organize your tests in Test Explorer with hierarchical sorting.

Hierarchy view for Text Explorer in Visual Studio

  • Live unit testing continuously runs tests impacted by your code changes and updates inline editor icons to let you know the status of your tests. Include or exclude specific tests or test projects from your live test set. (Visual Studio Enterprise edition only.)

For more information, see Unit test basics.


Some of Visual Studio's debugging capabilities include the following:

  • The ability to search for a string within the Watch, Autos, and Locals windows.
  • Run to click, which lets you hover next to a line of code, hit the green 'play' icon that appears, and run your program until it reaches that line.
  • The Exception Helper, which puts the most important information at the top level in the dialog, for example, which variable is null in a NullReferenceException.
  • Step back debugging, which lets you go back to previous breakpoints or steps and view the state of the application as it was in the past.
  • Snapshot debugging, which lets you investigate the state of a live web application at the moment an exception was thrown (must be on Azure).

Version control

In Visual Studio 2022, you can use Git directly from the IDE to create, review, check out, and run pull requests. To learn more, see How Visual Studio makes version control easy with Git.

You can use Git or TFVC to store and update your code in Visual Studio.

  • In Visual Studio 2019 version 16.8 and later, you can use Git from directly within the IDE to create, review, check out, and run pull requests.

  • In Visual Studio 2019 version 16.7 and earlier, install the Pull requests for Visual Studio extension to create, review, check out, and run pull requests without leaving Visual Studio.
