TypeName SA1404CodeAnalysisSuppressionMustHaveJustification
CheckId SA1404
Category Maintainability Rules

Cause

A Code Analysis SuppressMessage attribute does not include a justification.

Rule description

A violation of this rule occurs when the code contains a Code Analysis SuppressMessage attribute, but a justification for the suppression has not been provided within the attribute. Whenever a Code Analysis rule is suppressed, a justification should be provided. This can increase the long-term maintainability of the code.

[SuppressMessage("Microsoft.Performance", "CA1804:RemoveUnusedLocals", Justification = "Used during unit testing")]
public bool Enable()
{
}

How to fix violations

To fix an instance of this violation, add a Justification tag and justification text to the SuppressMessage attribute describing the reason for the suppression.
