How can I survive as Developer?

I am a good and curious developer with over 4 years of experience. But in my 4 years of experience I hardly created 6 web application using Wordpress and ASP.NET Webforms as my work place demand.

 

Now my problem is every one asks for ASP.NET MVC and all new buzzing words. It's hard for me to convince that I can work with MVC, and cannot get a position even as a Junior Developer. It's really getting tougher for me. Any advices will be helpful.

 

Thanks.
