c# .net json serialization dotnet-7 csharp

I'm trying to implement I'm refactoring my project and I've been struggling with this for a few days now and could really use some help... I'm working with an scenario when trying to deserialize a JSON array into a list of objects using System.Text.Json in my .NET 7 application. The JSON response I'm receiving looks like this: ```json [ {"Id": 1, "Name": "Item 1"}, {"Id": 2, "Name": "Item 2"} ] ``` I have a simple model defined as follows: ```csharp public class Item { public int Id { get; set; } public string Name { get; set; } } ``` When I attempt to deserialize the JSON into a `List<Item>`, I'm using the following code: ```csharp using System.Text.Json; var json = "[\n {\"Id\": 1, \"Name\": \"Item 1\"},\n {\"Id\": 2, \"Name\": \"Item 2\"}\n]"; var items = JsonSerializer.Deserialize<List<Item>>(json); ``` However, I encounter a `JsonException` with the message: "The JSON value could not be converted to System.Collections.Generic.List`1[YourNamespace.Item]." I've tried various approaches, including ensuring that the JSON is valid and checking the model for any discrepancies, but nothing seems to work. I also verified that the namespaces are correctly referenced, and there are no typos in the property names. I've attempted to debug the process by first serializing an `Item` object back to JSON and then ensuring that the structure matches what I'm trying to deserialize. This worked fine, but the deserialization part continues to unexpected result. Is there a common mistake I might be making, or is there an alternative approach I should try? Any insights or suggestions would be greatly appreciated. Any help would be greatly appreciated! Thanks for your help in advance! I'm coming from a different tech stack and learning Csharp. Could this be a known issue? I'd be grateful for any help.
