PocoDataSet.Extensions Library

The PocoDataSet.Extensions library provides a comprehensive set of extension methods and helper components built on top of the core POCO DataSet interfaces. Its purpose is to make IDataSet, IDataTable, and IDataRow easier to construct, transform, synchronize, and consume in real-world, metadata-driven applications.

This library intentionally keeps the core data model small and stable, while layering higher-level behavior—such as merge strategies, POCO integration, schema helpers, and value conversion—into a separate, opt-in assembly.

Purpose of PocoDataSet.Extensions

• Provide expressive, intention-revealing APIs on top of the core POCO DataSet abstractions.
• Reduce repetitive boilerplate when creating tables, rows, and columns programmatically.
• Support synchronization workflows (changeset creation, save, refresh, merge).
• Centralize value conversion, reflection-based mapping, and merge logic in one place.

Main Areas in This Library

• DataSet Extensions Group
  Dataset-level orchestration helpers: table creation and lookup, changeset generation, Accept / RejectChanges, and dataset merging.
• DataTable Extensions Group
  Table-level helpers for schema management, row lifecycle, cloning, indexing, conversion to collections, and table merging.
• DataRow Extensions Group
  Row-level helpers for row creation, typed reads, POCO import/export, live interface proxies, and row merging.
• DataSetFactory Class
  Centralized factory for creating empty datasets and core objects.

Design Notes

• Extensions are layered. Core POCO DataSet types remain lightweight and free of higher-level behavior.
• Live vs detached mappings are explicit. Methods like AsInterface return live proxies, while methods like ToPoco return detached copies.
• Merge behavior is configurable. All merge operations delegate to handlers selected via IMergeOptions.

When to Use PocoDataSet.Extensions

Use PocoDataSet.Extensions whenever you need more than raw data containers: when building dynamic UIs, mapping between transport and domain models, synchronizing client / server state, or implementing metadata-driven workflows. The extensions keep higher-level application code focused on intent rather than low-level data manipulation.
