ASP.NET? 2.0 is compatible, can be running, the only thing is the 2003 debugging will fail, if you want to solve the IIS's ASP2 support, reinstall the 1.x, 2005, use the web server that comes with him, everyone is good : D
Let .NET 1.1 is not affected by the installation of VS2005, you have to register your .NET 1.1 to IIS, remember, -i / -r runs separately. Reference website:
