When you use Microsoft Visual Studio .NET 2003 to open a Microsoft ASP.NET
1.0 project on a Web server that is running ASP.NET version 1.1, you may
receive the following "ASP.NET Version Mismatch" error message:
Visual Studio .NET has
detected that the 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 application will not be able to use new
features from ASP.NET 1.1.
