Supported Data Types

POCO DataSet supports a range of fundamental .NET types suitable for JSON serialization and dynamic UI rendering. All supported types are compatible with runtime metadata inspection and predictable roundtripping across application layers.

Common Primitive Types

• int, long, short
• decimal, double, float
• bool
• string
• Guid
• DateTime

Nullable Types

Every value type is supported in its nullable form. Nullability is controlled at the metadata level, enabling schemas to express optional or required values clearly.

Enums

Enumerations are supported as long as they can be represented in JSON. They are useful for dropdowns or limited-choice fields.
