Deploying .NET Application on Bluemix, connecting to external databases, Watson

I have an application built on .NET Framework using MVC 5 and SQL Server 2008 R2 Enterprise Edition which I want to deploy on Bluemix.

1. Does Bluemix Support .NET. If I deploy my .NET application on Bluemix, would it work?
2. I have Virtual Servers hosting the application and data for my Application on a separate hosting provider. If I deploy some components of my application (built on Bluemix supported technologies such as Java/ php/ node.js/ DB2) on Bluemix, will I still be able to communicate with my database etc. deployed outside of the Bluemix (and on a different hosting provider).
3. If I deploy my application on Bluemix, will I need to necessarily consume Watson APIs? Does my deployment on Bluemix necessarily have to do anything with Watson or Watson Services? Can I deploy my application without consuming Watson APIs?

Many Thanks!!
