Deserializing JSON to a string or a value

This article addresses a common challenge in API integration: handling JSON responses where a property can be either a string or another type (like a boolean). It discusses the limitations of standard deserialization in C#, presents a workaround using JsonElement, and then introduces a robust solution via a custom StringOrValue<T> struct. The implementation leverages modern C# features and a custom JsonConverter to create a type-safe, communicative way to manage these dual-state values in .NET applications.
