I followed the instructions at Upgrading an ASP.NET MVC 3 Project to ASP.NET MVC 4 to convert ASP.NET MVC 3 to MVC 4. However, I've got lots of errors. It looks like Microsoft added DisplayNameExtensions.DisplayNameFor, thus conflicting with my own DisplayNameFor extension that does the same thing. LabelExtensions.LabelFor
Using NuGet, I upgraded from Web API RC to Web API RTM. However, for me, my project won't compile. QueryableAttribute is missing! Turns out that I've to add the new package Microsoft.AspNet.WebApi.OData to get the attribute back. Being a little risk adverse because the package is in alpha, I chose to remove all references to QueryableAttribute instead.
