Specifies that code or an assembly performs security-critical operations.
Assembly: mscorlib (in mscorlib.dll)
[AttributeUsageAttribute(AttributeTargets::Assembly | AttributeTargets::Class | AttributeTargets::Struct | AttributeTargets::Enum | AttributeTargets::Constructor | AttributeTargets::Method | AttributeTargets::Field | AttributeTargets::Interface | AttributeTargets::Delegate, AllowMultiple = false, Inherited = false)] public ref class SecurityCriticalAttribute sealed : Attribute
This API supports the product infrastructure and is not intended to be used directly from your code. Returns a value that indicates whether this instance is equal to a specified object.(Inherited from Attribute.)
Returns the hash code for this instance.(Inherited from Attribute.)
When overridden in a derived class, indicates whether the value of this instance is the default value for the derived class.(Inherited from Attribute.)
When overridden in a derived class, returns a value that indicates whether this instance equals a specified object.(Inherited from Attribute.)
Returns a string that represents the current object.(Inherited from Object.)
|_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.)
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.)
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 attribute or the SecuritySafeCriticalAttribute attribute must be applied to code for the code to perform security-critical operations.
Theis equivalent to a link demand for full trust. A type or member marked with the 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 SecurityCriticalScope::Everything.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
