Sign in with google plus ID error "could not load file or assembly 'System.Net.Http.Primitives, Version=1.5.0.0"

Question

I am implementing sign-in with google-plus in my web. But after signing in, this error occurs,

Could not load file or assembly 'System.Net.Http.Primitives, Version=1.5.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040) Please try again in several minutes.

I've tried every steps that is mentioned here : Could not load file or assembly System.Net.Http.Primitives. Located assembly's manifest definition does not match the assembly reference

At last, I've fixed this problem with adding this to machine.config :

<runtime>
  <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
    <dependentAssembly>
      <assemblyIdentity name="System.Net.Http.Primitives" publicKeyToken="b03f5f7f11d50a3a" culture="neutral"/>
      <bindingRedirect oldVersion="0.0.0.0-4.0.10.0" newVersion="4.0.10.0"/>
    </dependentAssembly>
  </assemblyBinding>
</runtime>

Problem : I don't want a machine.config changed so I want to move it to web.config on a root folder of my web.

Is there any other solution?

Finally I found how to fix this.. deleting xmlns="http://schemas.microsoft.com/.NetConfiguration/v2.0" from tag fix my problem.. I don't know what's the side effect of that action, can someone tell me??
