Attributes and Elements

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

Attributes

Attribute	Description
apply	Specifies whether to apply publisher policy.

apply Attribute

Value	Description
yes	Applies publisher policy. This is the default setting.
no	Does not apply publisher policy.

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 assembly binding and garbage collection.

Remarks

When a component vendor releases a new version of an assembly, the vendor can include a publisher policy so applications that use the old version now use the new version. To specify whether to apply publisher policy for a particular assembly, put the <publisherPolicy> element in the <dependentAssembly> element.

The default setting for the apply attribute is yes. Setting the apply attribute to no overrides any previous yes settings for an assembly.

Permission is required for an application to explicitly ignore publisher policy using the <publisherPolicy apply="no"/> element in the application configuration file. The permission is granted by setting the BindingRedirects flag on the SecurityPermission Class. For more information, see Assembly Binding Redirection Security Permission.

Example

The following example turns off publisher policy for the assembly, myAssembly.

<configuration>
   <runtime>
      <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
         <dependentAssembly>
            <assemblyIdentity name="myAssembly"
                                    publicKeyToken="32ab4ba45e0a69a1"
                                    culture="neutral" />
            <publisherPolicy apply="no"/>
         </dependentAssembly>
      </assemblyBinding>
   </runtime>
</configuration>
