Facebook / Twitter integration for asp.net/VB.net website

I need to have a facebook / twitter login implementation. Below are job details: 1. Create Master page 2. Create login page with master page and code behind vb.net 3. Add two button Login with facebook and Login with twitter 4. Once user click on facebook then you need to validate user with a ms-access database . Create an User table inside that with just two fields. UID, Email. If Facebook authenticated tehn you need to check in code behind like Email in our User table or not. If no email found then throw error message "No user found". If found then store email in session and redirect them to [login to view URL] 4. same thing for Twitter login. Thanks
