与ASP.NET Core(以前称为Asp.Net 5)相比，ASP.NET 4中处理自引用循环的方式没有区别.您在帖子中引用的问题中概述的原则仍然适用.但是，鉴于配置和引导应用程序的新方法，在ASP.NET Core中设置此属性显然稍有不同:

There is no difference in the way self-referencing loops are handled in ASP.NET 4 compared to ASP.NET Core (previously Asp.Net 5). The principles outlined in the question you referenced in your post still apply. However, setting this property in ASP.NET Core is obviously slightly different, given the new method of configuring and bootstrapping the app:

public void ConfigureServices(IServiceCollection services)
{
    services.AddMvc().AddJsonOptions(options => {
        options.SerializerSettings.ContractResolver = new CamelCasePropertyNamesContractResolver();
        options.SerializerSettings.ReferenceLoopHandling = ReferenceLoopHandling.Ignore;
    });
    services.AddEntityFramework().AddSqlServer().AddDbContext<IvoryPacketDbContext>(
        options => options.UseSqlServer(Configuration["Data:DefaultConnection:ConnectionString"])
    );
}
