ASP.NET (IIS 7 or newer)

.NET Framework version

Select the .Net Framework version that will be loaded by this application pool. An application pool can only load one .NET Framework version; all applications in the application pool must use the same version.

  • No Managed Code - select this option if the applications that you want to assign to this application pool do not contain managed code
  • v1.1 - specifies that the application pool will use .NET Framework 1.1
  • v2.0 - specifies that the application pool will use .NET Framework 2.0, 3.0 or 3.5
  • v4.0 - specifies that the application pool will use .NET Framework 4.0

Managed pipeline mode

Select one of the following values from the list to specify how IIS processes requests for managed content:

  • Integrated - IIS processes requests for managed content with the integrated IIS and ASP.NET request-processing pipeline.
  • Classic - IIS processes requests for managed content with the separate IIS and ASP.NET request-processing pipelines. Use this mode only when the applications in the application pool cannot run in Integrated mode.

Warning!If you use .NET Framework version 1.1, the "Managed pipeline mode" option will be ignored.

Enable 32-bit applications on 64-bit Windows

If you check this option, on 64-bit versions of Windows the worker process(es) serving the application pool will be in WOW64 mode. Processes in WOW64 mode are 32-bit processes that can load only 32-bit applications.
