realm-dotnet: Can't set a property of a RealmModel in 0.81.0

Goal

The goal is to be able to unit test my PCLs without deploying to the device for faster test time.

In 0.78.1 we were able to new up a class overriding RealmObject, however we are unable to do so in 0.81.0.

This blocks us from upgrading the version since we are entirely unable to test our entire data access layer.

Expected Results

I should be able to:

• Mock the Realm object #537
• Either mock (#529) or create and manipulate RealmModels that are pointing to the “bait” nuget package without having exceptions.

Actual Results

In 0.78.1 I am able to new up a RealmModel, set properties to it and use it in my mocks, while mocking a wrapper layer around the Realm object as a workaround on #537.

In 0.81.0 when setting a property in the unit tests the object checks if it is managed, throwing an exception because of an unimplemented method in the “bait” nuget.

Steps & Code to Reproduce

Write a nunit project in Xamarin studio that uses the bait Realm nuget package to test the business logic of your app.

New an object that extends RealmObject and set a property to it.

Using 0.78.1 the code will work, using 0.81.0 it fails.

Code Sample

    // Model
    public class Person : RealmObject
    {
        public string Name { get; set; }
    }

    // Failing unit test
    [Test]
    public void Test_PersonCreation()
    {
           new Person { Name = "This fails on 0.81.0, but not on 0.78.1" }
    }

Version of Realm and tooling

Realm version(s): 0.78.1 works, 0.81.0 fails

Xamarin Studio version: 6.1.2

Which operating system version and device: Nunit projects running on an iMac and Windows 10 against the bait nuget package.
