C# Entity Framework returning broken JSon when using Include in DbSet
If you are using Json.net you probably need to change the DefaultSettings to handle the serialization
JsonConvert.DefaultSettings = () => new JsonSerializerSettings{ PreserveReferencesHandling = PreserveReferencesHandling.All, ReferenceLoopHandling = ReferenceLoopHandling.Serialize};Or depending on your particular requirements
- None : Do not preserve references when serializing types.
- Objects : Preserve references when serializing into a JSON object structure.
- Arrays : Preserve references when serializing into a JSON array structure.
- All : Preserve references when serializing.
- Error : Throw a JsonSerializationException when a loop is encountered.
- Ignore : Ignore loop references and do not serialize.
- Serialize :Serialize loop references.
