SecurityRulesAttribute Class

[This documentation is for preview only, and is subject to change in later releases. Blank topics are included as placeholders.]

Indicates the set of security rules the common language runtime should enforce for an assembly.

Namespace: System.Security
Assembly: mscorlib (in mscorlib.dll)

Syntax

Visual Basic (Declaration)

<AttributeUsageAttribute(AttributeTargets.Assembly, AllowMultiple := False)> _
Public NotInheritable Class SecurityRulesAttribute _
    Inherits Attribute

Visual Basic (Usage)

Dim instance As SecurityRulesAttribute

[AttributeUsageAttribute(AttributeTargets.Assembly, AllowMultiple = false)]
public sealed class SecurityRulesAttribute : Attribute

Visual C++

[AttributeUsageAttribute(AttributeTargets::Assembly, AllowMultiple = false)]
public ref class SecurityRulesAttribute sealed : public Attribute

[<SealedAttribute>]
[<AttributeUsageAttribute(AttributeTargets.Assembly, AllowMultiple = false)>]
type SecurityRulesAttribute =  
    class
        inherit Attribute
    end

Remarks

This class indicates which set of security rules the common language runtime should enforce for an assembly. For example, an assembly that is marked with [SecurityRules(SecurityRuleSet.Level1)] uses the .NET Framework version 2.0 transparency rules, where public security-critical types and members are treated as security-safe-critical outside the assembly. This requires security-critical types and members to perform a link demand for full trust to enforce security-critical behavior when they are accessed by external callers. Typically, level 1 rules should be used only for compatibility, such as for version 2.0 assemblies. For more information about level 1 behavior, see Security-Transparent Code, Level 1. For information about level 2 behavior, see Security-Transparent Code, Level 2.
