[asp.net] Could not load file or assembly 'Newtonsoft.Json, Version=4.5.0.0, Culture=neutral, PublicKeyToken=30ad4fe6b2a6aeed'

I was writing a WebApi REST service client, so for me this error was caused by adding References to the System.Net.Http and System.Net.Http.Formatting assemblies manually via Add Reference, when I should have added the Microsoft.AspNet.WebApi.Client package via NuGet. See also this answer to another question.
