Child Elements

None.

Parent Elements

Element

Description

configuration

Specifies the required 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 settings in a configuration file and contains configuration elements that configure ASP.NET Web applications and control how the applications behave.

pages

Defines page-specific configuration settings, such as global ASP.NET directives, for pages and controls that are within the scope of the configuration file.

namespaces

Defines a collection of import directives to use during assembly pre-compilation.

The remove element removes a reference to an inherited namespace from the collection of namespaces that is stored in the namspaces element.

The namespaces element defines a collection of import directives to use during assembly pre-compilation. This attribute corresponds to the @ Import directive on an ASP.NET page. The @ Import directive lets you specify namespaces that are automatically imported into all pages of an application.

Default Configuration

The following default namespaces element is configured in the root Web.config file. You can remove any of these namespaces from the collection by using the remove element in the Web.config file for an application.

<pages>
   <namespaces>
      <add namespace="System" />
      <add namespace="System.Collections" />
      <add namespace="System.Collections.Specialized" />
      <add namespace="System.Configuration" />
      <add namespace="System.Text" />
      <add namespace="System.Text.RegularExpressions" />
      <add namespace="System.Web" />
      <add namespace="System.Web.Caching" />
      <add namespace="System.Web.SessionState" />
      <add namespace="System.Web.Security" />
      <add namespace="System.Web.Profile" />
      <add namespace="System.Web.UI" />
      <add namespace="System.Web.UI.WebControls" />
      <add namespace="System.Web.UI.WebControls.WebParts" />
      <add namespace="System.Web.UI.HtmlControls" />
   </namespaces>
   <!-- Other elements -->
</pages>

The following code example shows how to remove an inherited namespace from pre-compilation.

<configuration>
   <system.web>
      <pages>
         <namespaces>
            <remove namespace="System.Text.RegularExpressions"/>
         </namespaces>
      </pages>
   </system.web>
</configuration>
