How to stop newtonsoft json from camelcasing

Question

Configuration:

• Azure Web API, C#, ASP.NET CORE 2.2
• Windows Client, C#, .NET Framework 4.7.2
• Newtonsoft JSON for serializing objects between Server and Client

Problem:

When sending a DataTable, Newtonsoft JSON is always changing the column captions to camelCase.

For example, a column called CostObjectKey is shown as costObjectKey after the transmission.

How can I stop Newtonsoft from doing this? I want my column captions unchanged.

In your startup's ConfigureServices you can add MvcJsonOptions.

services
    .AddMvc()
    .AddJsonOptions(options =>
    {
        options.SerializerSettings.ContractResolver =
            new Newtonsoft.Json.Serialization.DefaultContractResolver();
    });
