Attributes

None.

Child Elements

Subtag	Description
add	Optional element. Adds an assembly reference to the collection.
clear	Optional element. Removes all references to inherited assembly names, allowing only the references that are added by the current add element.
remove	Optional element. Removes a reference to an inherited assembly name from the collection.

Parent Elements

Element	Description
configuration	Specifies the root element in every configuration file that is used by the common language runtime and the .NET Framework applications.
system.web	Specifies the root element for the ASP.NET configuration section.
compilation	Configures all the compilation settings that ASP.NET uses to compile applications.

Remarks

The assemblies element defines a collection of assembly names that are used during compilation of an ASP.NET application.

Default Configuration

The following default assemblies element is not explicitly configured in the Machine.config file or in the root Web.config file. However, it is the default configuration that is returned by the application. Items are added to the assemblies collection in the root Web.config file.

<assemblies>
   <clear />
</assemblies>

The following default assemblies element is configured in the root Web.config file.

<assemblies>
    <add assembly="mscorlib" />
    <add assembly="System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" />
    <add assembly="System.Configuration, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />
    <add assembly="System.Web, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />
    <add assembly="System.Data, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" />
    <add assembly="System.Web.Services, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />
    <add assembly="System.Xml, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" />
    <add assembly="System.Drawing, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />
    <add assembly="System.EnterpriseServices, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />
    <add assembly="System.Web.Mobile, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />
    <add assembly="*" />
</assemblies>

Example

The following code example demonstrates how to add an assembly reference to an application.

<configuration>
  <system.web>
   <compilation>
      <assemblies>
         <add assembly="System.Data, Version=1.0.2411.0, 
                        Culture=neutral, 
                        PublicKeyToken=b77a5c561934e089"/>
      </assemblies>
   </compilation>
  </system.web>

</configuration>
