It's essential to set the starting page of your ASP.net application in IIS. Here I have provided the solution to do that

• Go to Start -> Run
• Type "inetmgr" then press Enter
• In the Default Web Site right click your web application then select Properties
• Navigate to Documents tab
• Add the page name with extension by clicking the add button
• Press Apply

It will work now!
