how about the career in .NET

Question

hello sir,

 

I'm a BPO folk who is working in IT application support domain from past 1.5 years as an IT application support analyst. as i told earlier i'm not from IT back ground. But now i'm use to it. So i want to continue my career in IT domain itself. but want to move to further level (like a tester or developer) so i'm taking .NET course from NIIT. But someone told me that there is no well growth in .net . So .net developers are the second least in secure job it seems. is it so? please do advise me how about the career growth in .net for starter? also i'm pretty much aware of web development like HTML & CSS.
