web-api POST body object always null

Question

I\'m still learning web API, so pardon me if my question sounds stupid.

I have this in my StudentController:

public HttpResponseMessage          


        

Answer 1

In my case (.NET Core 3.0) I had to configure JSON serialization to resolve camelCase properties using AddNewtonsoftJson():

services.AddMvc(options =>
{
    // (Irrelevant for the answer)
})
.AddNewtonsoftJson(options =>
{
    options.SerializerSettings.ContractResolver = new CamelCasePropertyNamesContractResolver();
});

Do this in your Startup / Dependency Injection setup.
