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