Moq.SetupGet doesn't work with Mock.Of<>

[ghost]

When a mock is created with new Mock<>, a getter can be modified with SetupGet.
When a mock is created with Mock.Of<>, SetupGet doesn't seem to work.

Code sample :

    public static void Test()
    {
        var mockConnection1 = new Mock<EntityConnection>();
        var connection1 = mockConnection1.Object;
        mockConnection1.SetupGet(c => c.ConnectionString).Returns("_");

        var connection2 = Mock.Of<EntityConnection>();
        var mockConnection2 = Mock.Get(connection2);
        mockConnection2.SetupGet(c => c.ConnectionString).Returns("_");

        Assert.Equal("_", connection1.ConnectionString); // OK
        Assert.Equal("_", connection2.ConnectionString); // "_" != null
    }

I'm using nuget 4.7.145

I cannot reproduce that issue given Moq 4.7.145, your test code, and a straightforward definition for EntityConnection such as:

public interface EntityConnection
{
    string ConnectionString { get; set; }
}

Could you please update your repro code to be minimally complete (i.e. include the relevant parts of the type that you're mocking), and make sure it reproduces the issue you're describing?

I could reproduce the problem with the following type definition:

public abstract class DbConnection
{
    public abstract string ConnectionString { get; set; }
}

public class EntityConnection : DbConnection
{
    public override string ConnectionString { get; set; }
}

I can confirm that this issue has already been fixed in the develop branch (most likely thanks to #509), so your scenario should work just fine with the upcoming version of Moq (≥4.8.0).
