Key Features

• Automatic Serialization — Handled by the Cratis Application Model
• Type Safe — Compile-time validation through C# records
• Full-Stack — Use the same types on C# and TypeScript with automatic round-tripping

See Understanding Geospatial Types for concepts and when to use each type.
