SecurityTransparentAttribute Class

SecurityTransparentAttribute Class

[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]

Specifies that an assembly cannot access protected resources or functionality.


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

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

The SecurityTransparentAttribute type exposes the following members.

Public methodSecurityTransparentAttributeInitializes a new instance of the SecurityTransparentAttribute class.

Public methodEqualsInfrastructure. Returns a value that indicates whether this instance is equal to a specified object. (Inherited from Attribute.)
Protected methodFinalizeAllows an object to try to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.)
Public methodGetHashCodeReturns the hash code for this instance. (Inherited from Attribute.)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Public methodMatchWhen overridden in a derived class, returns a value that indicates whether this instance equals a specified object. (Inherited from Attribute.)
Protected methodMemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)
Public methodToStringReturns a string that represents the current object. (Inherited from Object.)

Transparent assemblies can be accessed from Windows Phone application code and cannot expose access to any protected resources or functionality.


Transparency is enforced by the just-in-time (JIT) compiler, not by the security infrastructure code. Applying this attribute to an assembly allows the assembly to access only transparent and security-safe-critical types and members regardless of its permission set, including full trust. Transparent code that accesses a security-critical type or member results in a MethodAccessException being thrown.

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
