I've been using
Steve Sharrock's ASP.Net FTP Deployment Tool (AND+FTP) for a while now (as
I mentioned here) and it is now a requirement in my development evironment.
Steve finally released the final version, if you work with ASP.Net and have both a development and live server, you probably NEED this tool. The functionality will be native in the next version of Visual Studio.Net, I think, but who can wait that long?
