After running a clean solution and rebuild, my MVC 4 Web API project stops working. It's can't find Newtonsoft.Json.
I know that MS is using this as the default JSON serializer now - but its not in the references list for the project, and I can't add it from NuGet as it says it's already installed.
Does anyone have any idea here as to what could be going wrong?

Task 1 - Creating the API ProjectRun Visual Studio 2012 Express for Web, to do this go to Start and type VS Express for Web then press Enter. From the File menu, select New Project. Select the Visual C# | Web project type from the project type tree view, then select the ASP.NET MVC 4 Web Application project type.
I would check the version of Newtonsoft. Json in the bin directory of the start up project. If Newtonsoft. Json is there and it is the version you are expecting, then you can use Fuslogvw (https://msdn.microsoft.com/en-us/library/e74a18c4(v=vs.110).aspx) to see where the loader is trying to get the 4.0.
Obsolete. The value types allowed by the JsonSchema. JSON Schema validation has been moved to its own package. See https://www.newtonsoft.com/jsonschema for more details.
Ok - found a work around myself, posting in case someone else gets caned by this MS bug. The problem is that you can't add a NuGet reference as it's already included in the packages by default. So...
