Newtonsoft Json Dll Instant

So pour one out for the DLL that refused to die. And then maybe add a reference to it, because your appsettings.json file still needs parsing. Have a Newtonsoft war story? A custom converter that saved your bacon? Share it in the comments below.

public class UnixDateTimeConverter : JsonConverter<DateTime> newtonsoft json dll

NullValueHandling = NullValueHandling.Ignore, ContractResolver = new DefaultContractResolver NamingStrategy = new SnakeCaseNamingStrategy() , Formatting = Formatting.Indented ; string json = JsonConvert.SerializeObject(myObject, settings); Need to serialize a DateTime as a Unix timestamp? Map an enum to a string instead of an int? Handle a polymorphic type hierarchy where the base class doesn’t know its children? JsonConverter is your answer. So pour one out for the DLL that refused to die

TypeNameHandling = TypeNameHandling.Auto ; (Warning: Only use this for trusted data—it's a security risk if you deserialize untrusted JSON.) Newtonsoft.Json is not the fastest library anymore. Microsoft's System.Text.Json is significantly faster, allocates less memory, and is more modern (using Utf8JsonReader and Utf8JsonWriter ). Benchmarks typically show System.Text.Json being 20-50% faster for serialization and 30-80% faster for deserialization. A custom converter that saved your bacon

Even with Microsoft's own System.Text.Json now baked into the platform, Newtonsoft.Json remains deeply embedded in countless production systems, legacy projects, and even modern greenfield development. Why? Because it’s battle-hardened, absurdly flexible, and packed with features that feel like magic.
