Your question is not very clear. First, are you asking about ASP or ASP.NET? They are not the same thing. This is not an ASP forum.
As for running on a tablet or phone, if you mean an asp.net project on the web, it runs in a browser and can run in a tablet's browser, a PC's browser or a phone's browser. If you are talking about a mobile application (not a website), that's a different
question.
