.NET Core 2.1 is Returning JSON with Lowercase Properties

Hi everyone,

Just testing out .Net Core 2.1 and noticed that all of my JSON properties are being returned in lowercase despite being defined as uppercase. It turns out that this is configurable:


// Change from this
services.AddMvc();

// To this
services
        .AddMvc()
        .AddJsonOptions(options => options.SerializerSettings.ContractResolver = new DefaultContractResolver());
