asp.net core 1.0 web api use camelcase

Question

On RC2 the same code returns json format with camel case. After netcore 1.0 release i started new project and the same code is returning json in lowercase.

Tried multiple solutions but none of them were working web-api-serialize-properties-starting-from-lowercase-letter

Solution 1

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

This keeps a JSON object's name the same as .NET class property.

Solution 2

You can configure JSON behavior this way:

public void ConfigureServices(IServiceCollection services)  
  {
      services.AddMvc()
                  .AddJsonOptions(options =>
                  {
                      options.SerializerSettings.ContractResolver =
                          new CamelCasePropertyNamesContractResolver();
                  });
  }

this actually now is the default behavior (unfortunately), he wanted Default, as is, no change in property names, case

What namespace/references does this require. There is no 'AddJsonOptions' that I'm able to see

[Brivvirs]

Its MVC6.namespace Microsoft.Extensions.DependencyInjection // Extensions methods for configuring MVC via an Microsoft.Extensions.DependencyInjection.IMvcBuilder. class MvcJsonMvcBuilderExtensions

@Omu These actually aren't the same (in .net core 2.0 anyway). The DefaultContractResolver will accept CamelCase and return TitleCase, the CamelCasePropertyNamesContractResolver accepts and returns CamelCase.

@Omu has this changed from .net core 1.x to 2.0 ?
