is there a way to set Controller.Json ReferenceLoopHandling property?
It is currently causing a self referencing loop when parsing entities with navigation propertie
This worked for me with .NET Core 3.0.
services.AddMvcCore().AddNewtonsoftJson( options => options.SerializerSettings.ReferenceLoopHandling = Newtonsoft.Json.ReferenceLoopHandling.Ignore);
