Create real time posts and comments in ASP.Net

Hello Forum,

My school project have been assigned and approved to me. The project is about creating a social media webpage with real time comments and posts. Please forum, I need your help.

How can I create social networking webpage in asp.net webpage (i.e aspx) where a user or users can post texts, images etc. and the post will be displayed on the page immediately the user clicks on "post" button.

The post will also come with time and date of the post?

I have searched the internet all round, but seem not to find a solution.

Please help me.
