Navigate quickly to files or types
Visual Studio has a feature called Go To All (Ctrl+T). Go To All enables you to quickly jump to any file, type, member, or symbol declaration.
- Change the location of this search bar or turn off the live navigation preview by using the gear icon.
- Filter results using syntax such as
t mytype
. - Scope your search to just the current document.
- Camel case matching is supported.
Enforce code style rules
You can use an EditorConfig file to codify coding conventions and have them travel with your source.
Add a default or .NET-style EditorConfig file to your project by choosing Add > New Item. 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. Android refactor package name.
Configure the severity level of a code style rule directly through the editor. If you currently do not have an .editorconfig file, one will be generated 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.
Check out the .NET coding convention options documentation, which also contains 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, click the broom icon at the bottom of the editor or press Ctrl+K, Ctrl+E.
You can also run code cleanup across your entire project or solution. Right-click on 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 clicking 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 FxCop 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. |
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
Starting in Visual Studio 2017, there are numerous improvements to the testing experience. You can test with the MSTest v1, MSTest v2, NUnit, or XUnit test frameworks.
Test Explorer test discovery is fast.
Organize your tests in Test Explorer with hierarchical sorting.
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.)
Debugging
Some of Visual Studio's debugging capabilities include:
- 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 aNullReferenceException
. - 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).

You can use git or TFVC to store and update your code in Visual Studio.
- Install the Pull requests for Visual Studio to create, review, check out, and run pull requests without leaving Visual Studio.
Organize your local changes in Team Explorer and use the status bar to track pending commits and changes.
Set up continuous integration and delivery for your ASP.NET projects inside of Visual Studio with the Continuous delivery tools for Visual Studio extension.
What other features should I know about?
Here is a list of editor and productivity features to make writing code more efficient. Some features may need to be enabled because they are off by default (they may index things on your machine, are controversial, or are currently experimental).
