ApiClient Not Loading Polly

[jasecoulls]

I have a reproducible issue. If I take the most simplest of code like this:

NSurveyGizmo.ApiClient client = new NSurveyGizmo.ApiClient {
ApiToken = "blah",
ApiTokenSecret = "blah"
};
List<NSurveyGizmo.Models.SurveyQuestion> q = client.GetQuestions(123456);

It will error out.

Could not load file or assembly 'Polly, Version=5.5.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference.

I've tried upgrading Polly to 7.0.0.0, downgrading to 5.5.0.0, uninstalling, reinstalling and I cannot seem to make this error go away.

Any help would be much appreciated.
