Deserializing with JSON.NET not working for class references

[carldebilly]

This won't deserialize :

public class A
{
    public string Str1 { get; }
}

public class B
{
    public A MyA { get; }
}

[...]
var b = JsonConvert.DeserializeObject<B>(json);

Proposed solution would be to generate a custom creation converter when a dependency to JSON.NET is detected.
