why NO .NET jobs?

Question

Hi, I am a fresh man from University of Bridgeport, Connecticut (MS in computer science). I have done wonderful projects in C#, ASP.NET. Who ever gets to know about my project, say that it’s really great. It's a Web based multi-tier, database oriented "stock market analyzer". I am searching for job since July and this is Oct, I haven't got any job in .NET. My GPA is above 3. NO SPONSORSHIP REQUIRED. Several jobs have come really close but just goes off… they call me to do requirements gathering or some time senior level job, but at last goes off...am ready to do any job based on .NET. I live in Stamford, Connecticut and am searching for job anywhere in Connecticut and New York City. Then why still? Is it a bad field.... or bad market for .net? Or bad for fresher alone ?am really frustrated... should I have to change my field? Awaiting advice, supu
