可是小猪不知道是啥时候引用了该死的这个4.5.0.0版本啊！！

这可折腾死小猪了！！不知道是何种原因，各种百度谷歌，最后还是看到老外的一个解释：

 

引用:

It's not clear what the relationships of the projects are, or when this error is occuring, but here's a guess. You have 3 projects the facebook project (refs 4.0.0.0 version), twitter project (refs 4.0.3.0 version), and a main project that refs both of those projects. You may be able to build this solution, but when you run the assembly binding will fail. Why? because the default behavior is to copy assemblies locally before running. What happens is that the first project to build copies to bin (say twitter) then the second project builds (facebook), then main. However, at the end of this the 4.0.0.0 version is sitting bin folder. When you run, as soon as you invoke something from twitter that tries to use the problem assembly the bind fails because it longer has access to the 4.0.3.0 version of the assembly. There are a couple of ways around this. One is register both assemblies in the GAC. If that isn't doable then look into assembly binding redirection in your config file. Another is to register for theAssemblyResolve event and load the assembly programmatically.

然后小猪按照其大概的方法增加了这么一句：

<runtime>
    <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
      <dependentAssembly>
        <assemblyIdentity name="Newtonsoft.Json" publicKeyToken="30ad4fe6b2a6aeed" culture="neutral" />
        <bindingRedirect oldVersion="0.0.0.0-4.5.0.0" newVersion="4.5.0.0" />
      </dependentAssembly>
    </assemblyBinding>
  </runtime>

OK了。这真是个蛋疼的下午！！
