.NET Core json serialization of properties on dynamic (ExpandoObject)

Question

I have a web api in .NET Core 1.0 and I like the new feature that properties are by default serialized to camelCasing instead of PascalCasing.<

Answer 1

This can be solved with this in Startup.cs -> ConfigureServices:

services.AddMvc().AddJsonOptions(opt =>
{
    opt.SerializerSettings.ContractResolver = new CamelCasePropertyNamesContractResolver();
});

It is mentioned a few places that this is now the default behavior for ASP.NET Core 1.0 but that is actually not true. Adding this line affects dynamic properties and those are not affected by default.
