Could not load file or assembly 'Google.Apis.Auth, Version=1.36.1.0

I am having the same issue as in the following issue #208

However, I am not updating I am adding those dependencies for the first time. I am unable to run an example successfully. I added the required configuration to a config file extracted an IConfigurationSection out of it and created an AdWordsUser to run the example.

var config = new AdWordsAppConfig(section);
codeExample.Run(new AdWordsUser(config));

The configuration settings get loaded successfully, but I get the following error:

System.IO.FileLoadException: Could not load file or assembly 'Google.Apis.Auth, Version=1.36.1.0, Culture=neutral, PublicKeyToken=4b01fa6e34db77ab'. An operation is not legal in the current state. (Exception from HRESULT: 0x80131509)

Start by reproducing the failure from the C# example at FirstApiCall.cs line 79, using AdWordsAppConfig and AdWordsUser as described. Read the OAuth call path around AdsOAuthProviderImpl.RefreshAccessTokenInOfflineMode and inspect how Google.Apis.Auth is loaded. Done means the example completes its API call without the FileLoadException.
