PublisherIdentityPermissionAttribute Class

Allows security actions for PublisherIdentityPermission to be applied to code using declarative security. This class cannot be inherited.

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

[SerializableAttribute]
[AttributeUsageAttribute(AttributeTargets.Assembly|AttributeTargets.Class|AttributeTargets.Struct|AttributeTargets.Constructor|AttributeTargets.Method, AllowMultiple = true, 
	Inherited = false)]
[ComVisibleAttribute(true)]
public sealed class PublisherIdentityPermissionAttribute : CodeAccessSecurityAttribute

The scope of the declaration that is allowed depends on the SecurityAction that is used.

The properties CertFile, SignedFile, and X509Certificate are mutually exclusive.

The security information declared by a security attribute is stored in the metadata of the attribute target and is accessed by the system at run time. Security attributes are used only for declarative security. For imperative security, use the corresponding permission class.

Important noteImportant Note:

   In the .NET Framework versions 1.0 and 1.1, identity permissions cannot have an Unrestricted permission state value. In the .NET Framework version 2.0, identity permissions can have any permission state value. This means that in version 2.0, identity permissions have the same behavior as permissions that implement the IUnrestrictedPermission interface. For information on executing version 2.0 applications with version 1.1 code access security (CAS) policy, see <legacyV1CASPolicy> Element.

NoteNote:

By default, code access security does not check for Publisher evidence. Unless your computer has a custom code group based on the PublisherMembershipCondition class, you can improve performance by bypassing Authenticode signature verification. This is accomplished by configuring the runtime to not provide Publisher evidence for code access security. For more information about how to configure this option and which applications can use it, see the <generatePublisherEvidence> element.

The following example of a declarative attribute shows the correct way to request PublisherIdentityPermission and states that you must have at least this permission to run your code. Code will only execute if signed with the Authenticode X.509v3 publisher certificate stored in the file "myX509.cer".

[assembly:PublisherIdentityPermissionAttribute(SecurityAction.RequestMinimum, CertFile = "MyX509.cer")]
//In C#, you must specify that you are using the assembly scope when making 
//a request.
