Hugo Estrada's House of Wonder

So I want to use the .Net DataContractJsonSerializer object. I check on msdn for what are the references that are needed:

http://msdn.microsoft.com/en-us/library/system.runtime.serialization.jso...

But it didn't work. I wasted about 20 minutes trying to troubleshoot what it was. I did a search on it, and I got the following answer:

using System.Runtime.Serialization;
using System.ServiceModel;

System.Runtime.Serialization.dll
System.ServiceModel.dll
System.ServiceModel.Web.dll

Grrr. What is wrong with that .Net documentation? So I go back, and scroll to the comments:

Regarding the problem mentioned earlier, i want to say this article is right: this class resides in System.Runtime.Serialization dll for the .NET Framework 4. The problem lies in the assembly version: although the class is contained in the version 4.0.0.0 assembly, you won't find it in earlier versions. This class was migrated from System.ServiceModel.Web to System.Runtime.Serialization in .NET 4.

Thus, if you are using .NET 3.5 SP1 or earlier, you should look for this class in System.ServiceModel.Web dll.

Ah! So that was the problem! Maybe this is a false memory, but wasn't there an easy way to toggle between the different versions of a page on the msdn site? That was useful.
