How To

How to add a managed module to application

  1. Open Internet Information Services (IIS) Manager:
    • If you are using Windows Server 2008 or Windows Server 2008 R2:
      • On the taskbar, click Start, point to Administrative Tools, and then click Internet Information Services (IIS) Manager.
    • If you are using Windows Vista or Windows 7:
      • On the taskbar, click Start, and then click Control Panel.
      • Double-click Administrative Tools, and then double-click Internet Information Services (IIS) Manager.
  2. In the Connections pane, expand the server name, expand Sites, and then go to the Web site or application to which you want to add a managed module.
  3. In the Home pane, double-click Modules.

  4. In the Actions pane, click Add Managed Module.
  5. In the Add Managed Module dialog box, enter the name of the managed module in the Name box, and then enter or select the module's .NET Framework fully-qualified type in the Type box.
  6. Select the Invoke only for requests to ASP.NET applications or managed handlers option if you want the module to respond only to managed requests.

  7. Click OK.



Attribute Description
name Required string attribute.

Specifies the unique name of a managed module on the Web server.

Optional string attribute.

Specifies conditions under which the module will run.

The preCondition attribute can be one or more of the following possible values. If you specify more than one value, separate the values with a comma (,).

Value Description
bitness32 Specify the bitness32 value when the module is a 32-bit .dll file. IIS should load the handler only for worker processes that run in WOW64 mode (32-bit simulation) on a 64-bit operating system.
bitness64 Specify the bitness64 value when the module is a 64-bit .dll file. IIS should load the handler only for worker processes that run in 64-bit mode.
integratedMode Specify the integratedMode value when the module should respond only to requests in application pools that are configured to use the integrated request-processing pipeline.
ISAPIMode Specify the ISAPIMode value when the module should respond only to requests in application pools that are configured to use Classic mode.
managedHandler Specify the managedHandler value when the module should process requests only for managed resources, such as .aspx files, and should not respond to requests for non-managed resources, such as .html files.
runtimeVersion1.1 Specify the runtimeVersionv1.1 value when the module should respond only to requests in application pools that are configured to use .NET Framework version 1.1.
runtimeVersion2.0 Specify the runtimeVersionv2.0 value when the module should respond only to requests in application pools that are configured to use .NET Framework version 2.0.
type Optional string attribute.

Specifies the managed type of a managed module. The type attribute does not apply to native modules.

Configuration Sample

The example configures a module for a Web application running in IIS 7 Integrated mode.

         <add name="Header" type="Contoso.ShoppingCart.Header"/>

Sample Code

Note: The examples in this document illustrate using a managed-code assembly that has been stored in the .NET Global Assembly Cache (GAC). Before using the code in these examples to deploy your own assemblies, you need to retrieve the assembly information from the GAC. To do so, use the following steps:

  • In Windows Explorer, open your C:\Windows\assembly path, where C: is your operating system drive.
  • Locate your assembly.
  • Right-click the assembly and click Properties.
  • Copy the Culture value; for example: Neutral.
  • Copy the Version number; for example:
  • Copy the Public Key Token value; for example: 426f62526f636b73.
  • Click Cancel.

The following code examples enable a managed module for a Web site named Contoso. The name property defines the name CartHeader for the module, the type property defines the managed type for the module, the preCondition property defines that IIS invokes the module only for managed requests.


appcmd.exe set config "Contoso" -section:system.webServer/modules /+"[name='CartHeader',type='Contoso.ShoppingCart.Header',preCondition='managedHandler']" 


using System;
using System.Text;
using Microsoft.Web.Administration;

internal static class Sample
   private static void Main()
      using (ServerManager serverManager = new ServerManager())
         Configuration config = serverManager.GetWebConfiguration("Contoso");
         ConfigurationSection modulesSection = config.GetSection("system.webServer/modules");
         ConfigurationElementCollection modulesCollection = modulesSection.GetCollection();

         ConfigurationElement addElement = modulesCollection.CreateElement("add");
         addElement["name"] = @"CartHeader";
         addElement["type"] = @"Contoso.ShoppingCart.Header";
         addElement["preCondition"] = @"managedHandler";
