What types of attacks are possible in web applications?

Question

I'm going to launch a new web application (ASP.Net), but I wonder how many types of attacks are possible in web applications that we need to take care of when creating the web application.

Since I am developing this web application from scratch, if I can get this list and determine what I need to take care of when creating the application, this will be a big help.
