Future of the Software Developer

Question

I am a software developer (.Net) and have 5 years experience on same. My problem is what would be the future of my carrier. Would I be able to hang on the same filed or have to change to any new technology. I have no clue what the future trends will be. Could someone share some ideas what the things I should learn and any platforms. If I am changing my path what it should be(ex: I heard Information Security is more popular) like wise.
