These analyzers are built into Visual Studio. The analyzer's diagnostic ID, or code format is IDExxxx, for example, IDE0001. You can configure preferences in the [text editor options page](../ide/code-styles-and-code-cleanup.md#code-styles-in-the-options-dialog-box) or in an [EditorConfig file](../ide/create-portable-custom-editor-options.md). Starting in .NET 5.0, code style analyzers are included with the .NET SDK and can be strictly enforced as build warnings or errors. For more information, see [Overview of .NET source code analysis](/dotnet/fundamentals/productivity/code-analysis).

To enforce consistent coding styles for everyone that works in a codebase, you can add an `.editorconfig` file to your solution or project. EditorConfig file settings adhere to a file format specification maintained by [EditorConfig.org](https://editorconfig.org). Many code editors and applications support EditorConfig files, including Visual Studio. Because the settings are in a file, they accompany your code, and can be used even outside of Visual Studio.

In Visual Studio, EditorConfig file settings take precedence over the various global text editor settings available under **Tools** > **Options** > **Text Editor** > **C/C++** > **Code Style**. You can use an EditorConfig file to tailor each codebase to use text editor settings that are specific to that project.

You can manually populate an EditorConfig file, or automatically generate it based on the code style settings you've chosen in Visual Studio. To create a new `.editorconfig` file based on your current Visual Studio settings, from the Visual Studio main menu choose **Tools** > **Options** > **Text Editor** > **C/C++** > **Code Style**. Then choose **Generate .editorconfig file from settings**. Choose the folder where your project is and then choose **Select Folder** to save the `.editorconfig`file.

When you use an EditorConfig file, you can still continue to set your own personal editor preferences in the Visual Studio text editor. These text editor settings apply whenever you're working in a codebase without an EditorConfig file, or when the EditorConfig file doesn't override a particular setting. An example of such a preference is whether to use tabs or spaces for the code indent style.

When you add an EditorConfig file to your project in Visual Studio, only new lines of code are formatted based on the EditorConfig settings. The formatting of existing code isn't changed unless you run one of the following commands:
Select **Code Cleanup** in the Visual Studio editor, or press **Ctrl**+**K**, **Ctrl**+**E**. This command applies to white-space settings, such as indent style, and selected code-style settings, such as parenthesis preferences.

When you add an EditorConfig file to your project in Visual Studio, only new lines of code are formatted based on the EditorConfig settings. The formatting of existing code isn't changed unless you run the **Code Cleanup** or **Format Document** commands. For more information, see [Apply code styles](../ide/code-styles-and-code-cleanup.md).
When you add an EditorConfig file to your project or codebase, Visual Studio formats any new lines of code you write according to the EditorConfig file settings. However, Visual Studio doesn't convert existing styles to the new ones until you format the document or run [Code Cleanup](../ide/code-styles-and-code-cleanup.md#apply-code-styles). For example, if the indents in your file are formatted with tabs and you add an EditorConfig file that formats indents with spaces, the indent characters aren't automatically converted to spaces. When you format the document (select **Edit** > **Advanced** > **Format Document** or press **Ctrl**+**K**, **Ctrl**+**D**), the white-space settings in the EditorConfig file are applied to existing lines of code.

When you add an `.editorconfig` file to a folder in your file hierarchy, its settings apply to all applicable files at that level and lower. You can also override EditorConfig settings for a particular project, codebase, or part of a codebase, such that it uses different conventions than other parts of the codebase. Doing so can be useful when you incorporate code from somewhere else, and don’t want to change its conventions.
