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

People have already talked about [JsonIgnore] being added to the virtual property in the class, for example:

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

I will also share another option, [JsonProperty(NullValueHandling = NullValueHandling.Ignore)] which omits the property from serialization only if it is null:

[JsonProperty(NullValueHandling = NullValueHandling.Ignore)]
public virtual Project Project { get; set; }
