Are there any tools and technology to use to develop a single page application in Html 5 using mvc .net

Here's what we are currently using

Asp.net mvc
Entity framework
Knockout Js
We are using SQL server database to create the data access using entity framework.

After looking at samples using knock.js we found that we need to pass the data in json format and we changed our controller to return data in json format and but we were getting an entity framework error doing some more searching we found a fix to create a dynamic object and return the data back in json format and that worked.

Continue along with the testing we were able to get a page to work. But what we ended up with was a lot of packing and unpacking data. Which seem a little redundant. I know there is not much detail but can anyone make a recondition on tools and technology that we can use to develop this website
