How to configure JsonOptions for controllers?

[hieucd04]

I'm migrating from Newtonsoft.Json to System.Text.Json and my controllers now refuse to bind its models because of incorrect default JsonOptions;

Usually, this should work:

services.AddControllers().AddJsonOptions(options =>
{
    options.JsonSerializerOptions.PropertyNameCaseInsensitive = true;
    options.JsonSerializerOptions.PropertyNamingPolicy = JsonNamingPolicy.CamelCase;
});

However, as far as I remember, OrchardCore doesn't allow calling AddControllers().

I tried this approach but it doesn't work:

public static void ConfigureServices(IServiceCollection services)
{
    services.AddOrchardCms().AddSetupFeatures("OrchardCore.AutoSetup");

    // I tried putting it everywhere: in application, in a module, etc -> not working!
    services.Configure<JsonOptions>(options =>
    {
        options.JsonSerializerOptions.PropertyNameCaseInsensitive = true;
        options.JsonSerializerOptions.PropertyNamingPolicy = JsonNamingPolicy.CamelCase;
    });
}

@hieucd04 OC uses Newtonsoft.Json

Good to know!
I removed Newtonsoft.Json from the project including the CamelCasePropertyNamesContractResolver -> that explains why my controllers are no longer working.
