This is going to be a strange question.

Does anyone know the requirements for developing using ASP.NET? By that I mean the software, server (web server etc) requirements.

As far as I know having VS.net and IIS are the only requirements.
The reason I am asking is we are having some training on ASP.NET and my boss is worrying we will not have the means to use the training and that it will be wasted.

we are alright as far as I know.
