Members

	Member name	Description
	Demand	All callers that are higher in the call stack are required to have been granted the permission that is specified by the current permission object.
	Assert	The calling code can access the resource that is identified by the current permission object, even if callers that are higher in the stack have not been granted permission to access the resource.
	Deny	Obsolete. The ability to access the resource that is specified by the current permission object is denied to callers, even if they have been granted permission to access it.
	PermitOnly	Only the resources that are specified by this permission object can be accessed, even if the code has been granted permission to access other resources.
	LinkDemand	The immediate caller is required to have been granted the specified permission.
	InheritanceDemand	The derived class that inherits the class or overrides a method is required to have been granted the specified permission.
	RequestMinimum	Obsolete. The request for the minimum permissions required for code to run. This action can be used only within the scope of the assembly.
	RequestOptional	Obsolete. The request for additional permissions that are optional (not required for code to run). This request implicitly refuses all other permissions that are not specifically requested. This action can be used only within the scope of the assembly.
	RequestRefuse	Obsolete. The request that permissions that might be misused will not be granted to the calling code. This action can be used only within the scope of the assembly.

Remarks

This class supports the .NET Framework for Silverlight library code and is not intended to be used by Silverlight application code. The class has been marked as obsolete so that it will display a compilation warning. You can use this class in a Silverlight-based application, but it will have no effect.
