JSON Question

dotPeek not showing all references

I'm looking at the

System.Web.Http
assembly in dotPeek and I can't see a reference to
Newtonsoft.Json


enter image description here

even though I know that
System.Web.Http.Results.JsonResult
uses
Newtonsoft.Json
as it's serializer unlike it's
System.Web.Mvc
cousin.

using Newtonsoft.Json;
using System;
using System.IO;
using System.Net;
using System.Net.Http;
using System.Net.Http.Headers;
using System.Text;
using System.Threading;
using System.Threading.Tasks;
using System.Web.Http;

namespace System.Web.Http.Results
{
/// <summary>
/// Represents an action result that returns an <see cref="F:System.Net.HttpStatusCode.OK"/> response with JSON data.
/// </summary>
/// <typeparam name="T">The type of content in the entity body.</typeparam>
public class JsonResult<T> : IHttpActionResult


Now I understand that
Newtonsoft.Json
will come down from Nuget in most instances if not already installed as per the
WebGrease
dependency but I don't understand why it doesn't show up in references.

It does show up as a comment in the AssemblyInfo file:

using System.Runtime.CompilerServices;
using System.Runtime.InteropServices;
using System.Runtime.Versioning;

So is this a setting, or a dotPeek quirk, or something about the way that assembly is built, or something else?

Answer

I know this is an old question, but while researching this I saw this unanswered post, so I thought I would answer it. The reason it doesn't show in dotPeek is because dotPeek does not show references for assemblies that it cannot load.

You can reproduce this fairly simply by creating a simple project with two assemblies where one references the other. If you copy the DLLs into a folder, and view the referencing assembly in dotPeek it will show the referenced assembly. Remove it from dotPeek, remove the referenced assembly from the folder and view the referencing assembly again - and you will see that reference has disappeared from dotPeek (apart from in the AssemblyInfo.cs as you mention above).

FWIW, Because of this issue I have moved to using ILSpy because that doesn't suffer from the same issue.
