Net Core Json Serializer

The quickest method of converting between JSON text and a.NET object is using the JsonSerializer.The JsonSerializer converts.NET objects into their JSON equivalent and back again by mapping the.NET object property names to the JSON property names and copies the values for you. However, Json.NET is frequently updated and application developers often want to - or even have to - use a specific version. Thus, we want to remove the dependency from ASP.NET Core 3.0 to Json.NET so that customers can choose which version to use, without fearing they might accidentally break the underlying platform. ASP.NET Core - Json serializer settings Enum as string and ignore null values - Startup.cs.

});

Also produce string values:

The EnumMemberAttribute is not sufficient for producing string-values but it is an useful addition to control the actual value of the serialized property, e.g.:

... serializing of MyClazz will then produce:

Any idea how to use this for .Net Core 3.0?

commented Sep 4, 2019

@lukaszciastko Try something like this to ignore nulls:
services.AddControllers().AddJsonOptions(options => options.JsonSerializerOptions.IgnoreNullValues = true);

Just add: using System.Text.Json.Serialization;. Unfortunately, it seems Swagger (Swashbuckle.AspNetCore 5.0.0-rc3) is not ready yet to handle this properly as in the generated doc the enum types are marked as int even if they are properly serialized as strings.
