Default option value | true |
// csharp_style_prefer_local_over_anonymous_function = true
int fibonacci(int n)
{
return n <= 1 ? 1 : fibonacci(n-1) + fibonacci(n-2);
}
// csharp_style_prefer_local_over_anonymous_function = false
Func<int, int> fibonacci = (int n) =>
{
return n <= 1 ? 1 : fibonacci(n - 1) + fibonacci(n - 2);
};
If you want to suppress only a single violation, add preprocessor directives to your source file to disable and then re-enable the rule.
#pragma warning disable IDE0039
// The code that's violating the rule is on this line.
#pragma warning restore IDE0039
To disable the rule for a file, folder, or project, set its severity to none
in the configuration file.
[*.{cs,vb}]
dotnet_diagnostic.IDE0039.severity = none
To disable all of the code-style rules, set the severity for the category Style
to none
in the configuration file.
[*.{cs,vb}]
dotnet_analyzer_diagnostic.category-Style.severity = none
