Attributes and Elements

The following sections describe attributes, child elements, and parent elements.

Attributes

Attribute	Description
enabled	Required attribute. Specifies whether the runtime creates Publisher evidence.

Enabled Attribute

Value	Description
false	Does not create Publisher evidence.
true	Creates Publisher evidence. This is the default.

Child Elements

None.

Parent Elements

Element	Description
configuration	The root element in every configuration file used by the common language runtime and .NET Framework applications.
runtime	Contains information about runtime initialization options.

Remarks

This element was introduced in the .NET Framework version 3.5 and applies only to that version. It has no effect in later versions of the .NET Framework.

The common language runtime (CLR) tries to verify the Authenticode signature at load time to create Publisher evidence for the assembly. However, by default, most applications do not need Publisher evidence. Standard CAS policy does not rely on the PublisherMembershipCondition. You should avoid the unnecessary startup cost associated with verifying the publisher signature unless your application executes on a computer with custom CAS policy, or is intending to satisfy demands for PublisherIdentityPermission in a partial-trust environment. (Demands for identity permissions always succeed in a full-trust environment.)

Note

We recommend that services use the <generatePublisherEvidence> element to improve startup performance. Using this element can also help avoid delays that can cause a time-out and the cancellation of the service startup.

Configuration File

This element can be used only in the application configuration file.

Example

The following example shows how to use the <generatePublisherEvidence> element to disable checking for CAS publisher policy for an application.

<configuration>
    <runtime>
        <generatePublisherEvidence enabled="false"/>
    </runtime>
</configuration>
