add Element for buildProviders for compilation (ASP.NET Settings Schema) 

Adds a build provider to the collection.

This element is new in the .NET Framework version 2.0.

<add 
   extension="custom resource file extension"
   type="build provider type, build provider assembly"
   Code | Resources | All"
/>

Attributes and Elements

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

Attributes

Attribute	Description
extension	Required String attribute. Defines the custom resource file extension. This attribute is the collection key. The default is an empty string ("").
type	Required String attribute. Defines the type and assembly to use to compile the files that are specified by the extension attribute. The default is an empty string ("").

Child Elements

None.

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 compilation settings that ASP.NET uses to compile applications.
buildProviders	Defines a collection of build providers that are used to compile custom resource files.

Remarks

The add element adds a build provider to the collection in the buildproviders element.

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