Unable to use library when also using NetTopologySuite converters.

[markphillips100]

I receive a JsonException: "Custom converter on member ... is not a JsonConverter" when trying to perform serialization of a Polygon typefrom the NetTopologySuite.

The specific reason for the error here is due to the fact NetTopologySuite derives several concrete types from a base Geometry type. They then have one single StjGeometryConverter : JsonConverter<Geometry> json converter, rather than separate converters per concrete type.

So, whether I use a Polygon, Point, or whatever concrete type for a property that I want serialized there is only ever the expectation that the GeoJsonConverterFactory will supply the single StJGeometryConverter.

Now, the method VerifyMemberConverterType here attempts to assert that the convert is JsonConverter<Polygon> which it will never be.

Any ideas how to get around this, considering it's highly unlikely NetTopologySuite will change their converters?
