Should I use WPF instead of ASP.NET

Question

Hi, from what i know i can use WPF to create browser app using C# code.

My question is , can a WPF application (that is to be viewed from internet browser),be accessed from a central server by many clients over the internet/intranet(intranet is my case),so that users don't need to install the app(except they must have prerequisite .net framework 3/3.5)

I am asking this because i have not learnt ASP.NET and WPF yet,so want to see if WPF is better AND future alternative.

-Thanks
