JSON.NET Error Self referencing loop detected for type

Question

I tried to serialize POCO class that was automatically generated from Entity Data Model .edmx and when I used

JsonConvert.SerializeObject 

Answer 1

The simplest way to do this is to install Json.NET from nuget and add the [JsonIgnore] attribute to the virtual property in the class, for example:

    public string Name { get; set; }
    public string Description { get; set; }
    public Nullable Project_ID { get; set; }

    [JsonIgnore]
    public virtual Project Project { get; set; }

Although these days, I create a model with only the properties I want passed through so it's lighter, doesn't include unwanted collections, and I don't lose my changes when I rebuild the generated files...
