Develop .Net 1.1 Web Application on windows Vista (IIS 7)

To develop Web application using .Net 1.1 and Visual Studio 2003 on Vista OS (IIS 7), follow the below steps:

  •   First of all you have to install Visual Studio 2003. this will install .Net 1.1 also

  •   Install all service packs for .Net framwork 1.1.

  •   Open the IIS Manager and navigate to the server root. (Not a website root, above that – the machine name.) and double click on "ISAPI and CGI restrictions."

  •   Add the v1.1 aspnet_isapi.dll to "Allowed" restrictions

                  (it’ll be at %WinDir%\Microsoft.NET\Framework\v1.1.4322\aspnet_isapi.dll)

  •   Navigate to the website root in IIS manager and double-click "ISAPI Filters."

  •   Add the ASP.NET 1.1 ISAPI filter from %WinDir%\Microsoft.NET\Framework\v1.1.4322\aspnet_filter.dll

  •   Go to the website root again in IIS manager and loo at "Advanced Settings."

  •   Ensure the website is using an ASP.NET 1.1 Application Pool (Vista created one for me when I installed .NET 1.1 – you may need to create one yourself.)
