In ASP.NET Core <3.0, JSON properties are camelCased by default (per this announcement).

You can disable this by replacing

services.AddMvc();

with

services
    .AddMvc()
    .AddJsonOptions(opt => opt.SerializerSettings.ContractResolver
        = new DefaultContractResolver());

in your Startup.cs file. You'll have to add using Newtonsoft.Json.Serialization; to the top of the file.

With the DefaultContractResolver in place, the property names will be represented verbatim in the JSON output. No need for DataMember attributes.
