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 buildProviders element defines a collection of build providers that are used to compile custom resource files of a particular file type and to generate code during compilation.

To define custom build actions for a file type within an ASP.NET application, you must derive a class from the BuildProvider class, implement members within the derived class for building the file type, and configure the build provider for the corresponding file extension within the application configuration file. For information, see BuildProvider.

Default Configuration

The following default buildProviders 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 application. Items are added to the buildProviders collection in the root Web.config file.

<buildProviders>
   <clear />
</buildProviders>

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

<buildProviders>
   <add extension=".aspx" type="System.Web.Compilation.PageBuildProvider"/>
   <add extension=".ascx" type="System.Web.Compilation.UserControlBuildProvider"/>
   <add extension=".master" type="System.Web.Compilation.MasterPageBuildProvider"/>
   <add extension=".asix" type="System.Web.Compilation.ImageGeneratorBuildProvider"/>
   <add extension=".asmx" type="System.Web.Compilation.WebServiceBuildProvider"/>
   <add extension=".ashx" type="System.Web.Compilation.WebHandlerBuildProvider"/>
   <add extension=".soap" type="System.Web.Compilation.WebServiceBuildProvider"/>
   <add extension=".resx" type="System.Web.Compilation.ResXBuildProvider"/>
   <add extension=".resources" type="System.Web.Compilation.ResourcesBuildProvider"/>
   <add extension=".wsdl" type="System.Web.Compilation.WsdlBuildProvider"/>
   <add extension=".xsd" type="System.Web.Compilation.XsdBuildProvider"/>
   <add extension=".js" type="System.Web.Compilation.ForceCopyBuildProvider"/>
</buildProviders>

Example

The following code example demonstrates how to define a build provider that is used to compile custom resource files with the specified extension.

<configuration>
   <system.web>
      <compilation>
         <buildProviders>
            <buildProvider 
               extension=".mafx" 
               type="MyBuildProviderType, MyBuildProviderAssembly" />
         </buildProviders>
      </compilation>
   </system.web>
</configuration>
