How would I connect to an online MySQL database using Visual Studio?

So far, I've tried doing it "the normal way" but I've come across a problem:

I cannot access "Org.Apache.Http.Impl" as it doesn't seem to be a part of my project. I don't know how to solve this, after much Googling.

This is the only thing that has stopped me so far, but I was wondering if there was something else that I was meant to be doing instead.

I'm currently using Visual Studio 2013 with the Xamarin plugin to create an Android Application.

Thanks,

Edit: Essentially, what I'm asking is (a) how do I get either Org.Apache.Http.Impl or MySql.Data into my project? (b) is there another way to do it? I was planning on using a PHP file to access the database, but I'd rather not have to
