JSON Serialization Approach

POCO DataSet is designed around JSON serialization as the primary transport format. The structure of DataSet, DataTable, and DataRow objects maps cleanly to JSON arrays and objects, making the payloads straightforward to inspect and transmit over HTTP.

Key Characteristics of the JSON Approach

• No XML-specific features or schema artifacts are required.
• DataSets serialize as ordinary JSON object graphs.
• Tables become collections of rows, with schema stored separately in metadata.
• Interfaces are handled by custom converters that map them to concrete implementations.
• The JSON produced is symmetrical—what is serialized can be deserialized without loss of information.

Serializer Configuration

Typically, JSON serialization is configured once at application startup. For example, using System.Text.Json:

JsonSerializerOptions options = new JsonSerializerOptions();
options.PropertyNameCaseInsensitive = true;

// Add POCO DataSet converters here
// e.g., ConcreteTypeConverter<IDataSet, DataSet>, etc.
