Answer 1

Remove all references to System.Threading.Tasks and then add in the one from whatever .NET version you are using (.NET 4.0).

The Google Calendar API might be using a different version of .NET

Manually Redirecting Assembly

You can specify which version of the assembly to use in your app.config

  <dependentAssembly>
    <assemblyIdentity name="someAssembly"
      publicKeyToken="32ab4ba45e0a69a1"
      culture="en-us" />

    <bindingRedirect oldVersion="7.0.0.0" newVersion="8.0.0.0" />
  </dependentAssembly>
