Suppress a warning

If you want to suppress only a single violation, add preprocessor directives to your source file to disable and then re-enable the rule.

C#
#pragma warning disable IDE0061
// The code that's violating the rule is on this line.
#pragma warning restore IDE0061

To disable the rule for a file, folder, or project, set its severity to none in the configuration file.

ini
[*.{cs,vb}]
dotnet_diagnostic.IDE0061.severity = none

To disable all of the code-style rules, set the severity for the category Style to none in the configuration file.
