Json Schema Patterns in .NET - Maps of strings to strongly typed values

In this post, we'll explore the common patterns of using unevaluatedProperties in conjunction with C# and JSON Schema to create maps of strings to strongly typed values. This is a powerful technique that allows you to define JSON objects with a flexible structure while still enforcing the expected types of their property values.

The technique involves using the unevaluatedProperties keyword in your JSON Schema to define a pattern that maps any string keys provided in an object to their corresponding strongly typed values. This enables you to construct JSON data that conforms to a schema without necessarily pre-defining all of its keys.

We delve into how to effectively use this pattern in C#, culminating in a fully-functional code sample demonstrating how to create a custom serializer for our expected schema format.

By the end of this post, you will learn how to leverage this powerful technique to build dynamic JSON objects, enforcing strongly typed values for properties while maintaining the flexibility of a schema supporting running system updates with minimal breaking changes.
