@Ambarishrh based off of builtwith.com I am working with ASP.NET

That's a start. So that still leaves you with dozens of language choices like Perl, Python, F#, Ruby and more. But 99% of the time the site that is ASP.NET will be built with C# or VB.NET. So you'll need to look at the code to determine which one, but C# looks like Java and VB.NET looks like it was written by a little kid, so they are pretty easy to tell apart 😉 No seriously, they look nothing alike, so it's normally super easy to tell.
