Rule ID IDE0076
Title Remove invalid global SuppressMessageAttribute
Category CodeQuality

Overview

This rule flags global SuppressMessageAttributes that have an invalid Scope or Target. The attribute should either be removed or fixed to refer to a valid scope and target symbol.

Options

This rule has no associated code-style options.

Example

// IDE0076: Invalid target '~F:N.C.F2' - no matching field named 'F2'
[assembly: System.Diagnostics.CodeAnalysis.SuppressMessage("Category", "Id: Title", Scope = "member", Target = "~F:N.C.F2")]
// IDE0076: Invalid scope 'property'
[assembly: System.Diagnostics.CodeAnalysis.SuppressMessage("Category", "Id: Title", Scope = "property", Target = "~P:N.C.P")]

// Fixed code
[assembly: System.Diagnostics.CodeAnalysis.SuppressMessage("Category", "Id: Title", Scope = "member", Target = "~F:N.C.F")]
[assembly: System.Diagnostics.CodeAnalysis.SuppressMessage("Category", "Id: Title", Scope = "member", Target = "~P:N.C.P")]

namespace N
{
    class C
    {
        public int F;
        public int P { get; }
    }
}

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.

#pragma warning disable IDE0076
// The code that's violating the rule is on this line.
#pragma warning restore IDE0076

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

[*.{cs,vb}]
dotnet_diagnostic.IDE0076.severity = none

To disable this entire category of rules, set the severity for the category to none in the configuration file.

[*.{cs,vb}]
dotnet_analyzer_diagnostic.category-CodeQuality.severity = none
