Rule categories

Each code analysis rule belongs to a category of rules. For example, design rules support adherence to the .NET design guidelines, and security rules help prevent security flaws. You can configure the severity level for an entire category of rules. You can also configure additional options on a per-category basis.

The following table shows the different code analysis rule categories and provides a link to the rules in each category. It also lists the configuration value to use in an EditorConfig file to bulk-configure rule severity on a per-category basis. For example, to set the severity of security rule violations to be errors, the EditorConfig entry is dotnet_analyzer_diagnostic.category-Security.severity = error.


Setting the severity for a category of rules using the dotnet_analyzer_diagnostic.category-<category>.severity syntax doesn't apply to rules that are disabled by default. However, starting in .NET 6, you can use the AnalysisMode<Category> project property to enable all the rules in a category.

EditorConfig value dotnet_analyzer_diagnostic.category-Reliability.severity
MSBuild property value <AnalysisModeReliability>

Security rules

Link to rules Security rules
Description Security rules support safer libraries and applications. These rules help prevent security flaws in your program.
EditorConfig value dotnet_analyzer_diagnostic.category-Security.severity
MSBuild property value <AnalysisModeSecurity>

Style rules

Link to rules Style rules
Description Style rules support consistent code style in your codebase. These rules start with the "IDE" prefix.*
EditorConfig value dotnet_analyzer_diagnostic.category-Style.severity
MSBuild property value <AnalysisModeStyle>

* Use the EditorConfig value dotnet_analyzer_diagnostic.category-CodeQuality.severity to enable the following rules: IDE0051, IDE0052, IDE0064, and IDE0076. While these rules start with "IDE", they aren't technically part of the Style category.

Usage rules

Description Usage rules support proper usage of .NET.
EditorConfig value dotnet_analyzer_diagnostic.category-Usage.severity
MSBuild property value <AnalysisModeUsage>
