Is it possible to create and maintain a .Net framework 1.1 application with Visual Studio 2005?
Actually, yes, you can, but it's not pretty and you still need .Net 1.1 on the machine. What you can't do is use Visual Studio to compile or build the site or open the solution file. You'll have to build it all from the command line. You'll get either spotty or incorrect intellisense support.
But you can use it like any other text editor to create the source files you need.
