NullReferenceException when accessing nested properties in a JSON response deserialization with Newtonsoft.Json in C#
I've hit a wall trying to I'm converting an old project and Quick question that's been bugging me - I'm working with a `NullReferenceException` when trying to access nested properties in a JSON response that I'm deserializing using Newtonsoft.Json in my .NET 6 application. The JSON structure looks like this: ```json { "user": { "id": 1, "name": "John Doe", "address": { "street": "123 Main St", "city": "Anytown" } } } ``` I created the following C# classes to match the JSON structure: ```csharp public class UserResponse { public User user { get; set; } } public class User { public int id { get; set; } public string name { get; set; } public Address address { get; set; } } public class Address { public string street { get; set; } public string city { get; set; } } ``` I am deserializing the JSON like this: ```csharp string jsonResponse = /* JSON response from API */; var userResponse = JsonConvert.DeserializeObject<UserResponse>(jsonResponse); var street = userResponse.user.address.street; // This line throws NullReferenceException ``` The exception occurs when I try to access `userResponse.user.address.street`. I've verified that the JSON response is valid and matches my class structure. I'm assuming the deserialization is not correctly populating the `address` property, but I need to figure out why. I've tried adding `[JsonProperty]` attributes to the classes, but it hasn't resolved the scenario. How can I ensure that the nested properties are being deserialized correctly? Any insights would be appreciated. This is my first time working with C# latest. I'm working with C# in a Docker container on Ubuntu 20.04. What are your experiences with this? My development environment is macOS. I'd really appreciate any guidance on this. This is part of a larger application I'm building.
