problem with asp.net on visual studio .net 2003

Question

I want to run ASP.NET on VS 2003 but it raises an error which says: "Visual studio has detected that web server is running asp.net version 1.0.The web application you are creating or opening can be configured to be compliant with asp.net 1.0. However, the web application will not be able to use the new features from asp.net 1.1."

When I choose the option "Make the application compliant with asp.net 1.0", then it is unable to set the compliance saying "Visual Studio.NET cannot create or open the application. The likeliest problem is that required components are not installed on the local web server. Run Visual Studio.NET setup and add the web development component."

Answer 1

It seems that you are running Visual Studio 2003 on Vista, which is not supported.

1. By default, Vista does not include .NET Framework 1.1 SP1. Install it first. Make sure that SP1 is installed. If you look into properties of "c:\Windows\Microsoft.NET\Framework\v1.1.4322\mscorsvr.dll", you should get the version 1.1.4322.2032.
2. Enable IIS 6 Compatibility in Control Panel -> Program and Features -> Turn Windows features on or off. Check "IIS 6 Management Compatibility" under "Internet Information Servces".
3. Register .NET 1.1 with IIS by running "*c:\Windows\MIcrosoft.net\Framework\v1.1.4322\aspnet_regiis.exe -ir*". It will create the Application Pool targeted to Framework 1.1 with Classic pipeline in IIS7 and set Enable32BitAppOnWin64 property to true on 64bit OS.
4. Allow ASP.NET 1.1 in IIS7. Open the IIS Manager and click on the computer name in left tree. In main window select "ISAPI and CGI Restrictions" and make sure that ASP.NET v1.1.4322 is enabled. If not, select it and click Allow link on right side.
5. When you create an application on any directory that runs .NET 1.1 or lower, always select Application Pool that is targeted to Framework 1.1. For already configured applications, you have to change it manually.

You may need to update the script map of the ASP.NET application within IIS to use the newer version of the framework. I assume that .NET 1.1 framework and VS 2003 are already installed without issues.

Here is an MSDN article that should explain how to register the ASP.NET application within IIS to use the .NET 1.1 version using the aspnet_regiis.exe tool. Command-line reference for the tool is available here.
