Cannot get Web API to work in VS 2010 or 2012

Question

I have a machine with the RC of VS 2012 and VS2010 running on it. I am trying to follow the code on http://www.asp.net/web-api/overview/getting-started-with-aspnet-web-api/tutorial-your-first-web-api to try out Web API. I tried following on the web some different links on how to fix problems, but still cannot get Web API to work using IIS Express/Cassini for the host on my Windows 7 x64 box. Currently I am getting "Method not found: 'Void Newtonsoft.Json.Serialization.DefaultContractResolver.set_IgnoreSerializableAttribute(Boolean)'." error when trying to look at what should be the list of products.

I followed the web page exactly as it is written and didn't add anything manually. I did set up the nightly repository for the web stack http://www.myget.org/F/aspnetwebstacknightly/, but don't know if that is causing the problem. Here's a dump of the NuGet's Get-Package on the program if it helps.

Answer 1

I turned on the "Include Prerelease" for NuGet and updated all the packages to the latest nightly release. It fixed the problem in VS 2012. Don't know about VS2010 though.
