I've developed a very simple ASP.NET (jQuery) application.
The RDBMS is MS Sql Server but I could easily convert it in MS Access.
My client would like to have it available on a CD, ready to run.
I was thinking to convert it in a WinForm app but, still, I have to install the framework on the client. Is there any other "possible" solution?
You're going to have more trouble trying to run a web app on a client machine than you will a desktop application.
A web app requires some sort of web server running, but a desktop app just needs the framework.
You're going to be better off converting it to a desktop app.
