Remarks

Important

Partially trusted code is no longer supported. This attribute has no effect in .NET Core.

Security-critical operations are actions that affect code access security, such as elevation of privilege through suppression of code access security checks by using the Assert method, calling unsafe managed code, and so forth. Either the SecurityCriticalAttribute attribute or the SecuritySafeCriticalAttribute attribute must be applied to code for the code to perform security-critical operations.

Note

The SecurityCriticalAttribute is equivalent to a link demand for full trust. A type or member marked with the SecurityCriticalAttribute can be called only by fully trusted code; it does not have to demand specific permissions. It cannot be called by partially trusted code.

Applying the SecurityCriticalAttribute at the assembly level identifies the assembly as a security-critical assembly. The entire assembly can be identified as critical by setting the scope parameter SecurityCriticalScope.Everything.

Constructors

SecurityCriticalAttribute()	Initializes a new instance of the SecurityCriticalAttribute class.
SecurityCriticalAttribute(SecurityCriticalScope)	Initializes a new instance of the SecurityCriticalAttribute class with the specified scope.

Properties

Scope	Obsolete. Gets the scope for the attribute.
TypeId	When implemented in a derived class, gets a unique identifier for this Attribute. (Inherited from Attribute)

Methods

Equals(Object)	Returns a value that indicates whether this instance is equal to a specified object. (Inherited from Attribute)
GetHashCode()	Returns the hash code for this instance. (Inherited from Attribute)
GetType()	Gets the Type of the current instance. (Inherited from Object)
IsDefaultAttribute()	When overridden in a derived class, indicates whether the value of this instance is the default value for the derived class. (Inherited from Attribute)
Match(Object)	When overridden in a derived class, returns a value that indicates whether this instance equals a specified object. (Inherited from Attribute)
MemberwiseClone()	Creates a shallow copy of the current Object. (Inherited from Object)
ToString()	Returns a string that represents the current object. (Inherited from Object)

Explicit Interface Implementations

_Attribute.GetIDsOfNames(Guid, IntPtr, UInt32, UInt32, IntPtr)	Maps a set of names to a corresponding set of dispatch identifiers. (Inherited from Attribute)
_Attribute.GetTypeInfo(UInt32, UInt32, IntPtr)	Retrieves the type information for an object, which can be used to get the type information for an interface. (Inherited from Attribute)
_Attribute.GetTypeInfoCount(UInt32)	Retrieves the number of type information interfaces that an object provides (either 0 or 1). (Inherited from Attribute)
_Attribute.Invoke(UInt32, Guid, UInt32, Int16, IntPtr, IntPtr, IntPtr, IntPtr)	Provides access to properties and methods exposed by an object. (Inherited from Attribute)
