how to Serialize Dictionary of Custom Objects with System.Text.Json in .NET 7
I'm dealing with I'm refactoring my project and I've looked through the documentation and I'm still confused about I am working with an scenario while trying to serialize a dictionary of custom objects using `System.Text.Json` in my .NET 7 application. The dictionary looks as follows: ```csharp public class Product { public int Id { get; set; } public string Name { get; set; } } var products = new Dictionary<int, Product> { { 1, new Product { Id = 1, Name = "Laptop" } }, { 2, new Product { Id = 2, Name = "Smartphone" } } }; ``` When I try to serialize this dictionary using: ```csharp var options = new JsonSerializerOptions { WriteIndented = true }; string json = JsonSerializer.Serialize(products, options); ``` I encounter the following exception: ``` System.Text.Json.JsonException: The JSON value could not be converted to System.Collections.Generic.IDictionary`2[System.Int32,YourNamespace.Product]. ``` I have already tried different approaches, such as: - Setting the `Dictionary`'s key type to `string`, but that didn't align with my requirements for an `int` key. - Using `JsonSerializerSettings` and configuring it for custom converters, but that seems to complicate the code without resolving the scenario. - Testing serialization with a simple list of products instead of a dictionary, which works perfectly fine. Is there a known limitation or a specific setting I need to configure for serializing dictionaries containing custom objects in .NET 7? Any help would be appreciated! What am I doing wrong? I'm developing on Ubuntu 20.04 with C#. Any examples would be super helpful. Could someone point me to the right documentation? I'm coming from a different tech stack and learning C#. What are your experiences with this? I'm working in a Debian environment. Thanks for your help in advance!
