Ask HN: Is using ASP.NET MVC, C# with Azure a bad idea for startup?

I have idea that I want to start working on (website first). I have experience with Microsoft stack c#, asp.net MVC 5 and Azure. I think these are very good tools if not the best. I am very excited for MVC 6. The only concern I have is to find people who would want to join me (In case I am on to something). the other option is to learn latest technologies in open source world and AWS but that will require lot of learning time for me.

Any thoughts?
