I've just started working on an ASP.NET project which I hope to open source once it gets to a suitable stage. It's basically going to be a library that can be used by existing websites. My preference is to support ASP.NET 2.0 through 3.5, but I wondered how many people I would be leaving out by not supporting ASP.NET 1.1? More specifically, how many people are there still using ASP.NET 1.1 for whom ASP.NET 2.0/3.5 is not an option? If upgrading your server is not an option for you, why not?

Increasingly I think not.

The kind of large rigid organisation currently still clinging to 1.1 (probably because they're only just upgraded to it) is also the kind that's highly unlikely to look at open source solutions.

If I were starting a new ASP.Net project right now I'd stick with .Net 3.5 and probably the new MVC previews.

I think you would be perfectly fine with targeting just 2.0 and above, someone who would use your library would most likely be doing new development and using at least ASP.NET 2.0. I think it would be a very small group of people doing new development in 1.1.

Remember that .NET 1.1 is going out of general support in October of this year (and that includes ASP.NET 1.1).
