Adds an assembly reference to the collection.

<add 
   assembly="Assembly 
             [,Version=version number] 
             [,Culture=culture] 
             [,PublicKeyToken=token]"
/>

Attributes and Elements

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

Attributes

Attribute	Description
assembly	Required String attribute. Specifies a comma-separated assembly combination consisting of version, culture, and public key tokens. ASP.NET searches for the assembly DLL first in the private Bin directory for the application, and then in the system assembly cache.

assembly

Required String attribute.

Specifies a comma-separated assembly combination consisting of version, culture, and public key tokens. ASP.NET searches for the assembly DLL first in the private Bin directory for the application, and then in the system assembly cache.

Child Elements

None.

Parent Elements

Element	Description
configuration	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 compilation settings that ASP.NET uses to compile applications.
assemblies	Defines a collection of names of assemblies that are used during compilation of an ASP.NET application.

Remarks

The add element adds an assembly reference to use during compilation of a dynamic resource. ASP.NET automatically links this assembly to the resource when compiling each code module.

The value of the add element is an assembly name, not a DLL path. ASP.NET looks up the assembly name to find its physical DLL location. Optionally, you can specify the asterisk (*) wildcard character to add every assembly within the private assembly cache for the application, which is located either in the \bin subdirectory of an application or in the.NET Framework installation directory (%systemroot%\Microsoft.NET\Framework\version\). For detailed information, see Load.

Default Configuration

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>
