I guess that most people that use Visual Studio had my same reaction when they created their first ASP.NET MVC project: where did the Design View end up?
Yes, I had that same reaction, coming from a webforms background. I need the constant feedback of a graphical designer to let me know what effect my code is having. Learning MVC is a big enough learning curve in and of itself without having to do it blindfolded.
Now that it's 4 years later, I don't mind saying Page Inspector is built in to VS 2013. If you're still using VS 2010 in 2015, all I can say is, if you upgrade, you'll never look back.
Just right click on the code and choose View in Page Inspector. There's an Inspect button in the inspector that you can use to see where an element of the design is located in the code. It can save you beaucoup time.
EDIT
And it looks like they removed it from Visual Studio 2015 and didn't even bother to post an explanation as to why. Smh...I'll update this if I find a 3rd party solution.
