В моем приложении используется следующий класс DTO / POCO, который передается через соединение SignalR:
class Base {
public string Value { get; set; }
}
class Child : Base {
public new string Value { get; set; }
}
Это хорошо работает в ASP.Net Core 2.2. Однако после перехода на 3.0 я сталкиваюсь со следующим исключением:
Error Message:
System.InvalidOperationException : The JSON property name for 'Biz4x.Frontend.Web.DTO.BoardRates.BoardTemplateWithRatesDTO.Template' collides with another property.
