• Enhanced "Value Object Mapping" with complex types: Prior to EF8, maneuvering objects structured to encapsulate multiple values sans a defining identity proved challenging. EF8 introduces "Complex Types" to address this niche. Unlike owned types - essentially entity types bound by key values - complex types:
  • Lack identification or tracking through key values.
  • Are integral parts of entity types, precluding the existence of DbSet for a complex type.
  • Span both .NET value types and reference types (Owned types restrict to reference types).
  • Permit shared instances among multiple properties, a feature absent in owned types.
• Immutable Records as complex types: The flexibility of EF8 extends to its compatibility with diverse .NET types for complex types in the EF model. Immutable record value types, especially, emerge as an exemplary fit for representing complex types. For instance, an immutable struct record effortlessly embodies a product:

  public readonly record struct Product(string name, string code, double amount);

  This implementation enables using the 'with' syntax to update properties, akin to working with immutable class records, offering simplicity and reliability.
• Handling primitive collections: EF8 confronts the perennial challenge of handling collections of primitive types in relational databases. For PostgreSQL users, native support simplifies storage using PostgreSQL's array type. For other databases, EF8 presents a streamlined approach - utilizing JSON as the serialization format. JSON's intrinsic compatibility with modern relational databases enables treating the JSON column akin to a table, sans the overhead of actual table creation.
• Strengthened query capabilities: Leveraging JSON for primitive collections unlocks new query translations, exploiting relational databases' JSON capabilities. This innovation facilitates inline, temporary tables creation for values, enhancing query efficiency and versatility.
• Expanded support - JSON columns: Building upon EF7's groundwork, EF8 extends support for mapping to JSON columns in SQLite databases, alongside PostgreSQL databases through the Npgsql.EntityFrameworkCore.PostgreSQL EF Core provider. This comprehensive support spans mapping aggregates, executing queries, and seamless updates to JSON documents.
• HierarchyId integration: Introducing HierarchyId type integration for Azure SQL and SQL Server, EF8 empowers the storage and manipulation of hierarchical data structures. This feature is instrumental in managing organizational structures, file systems, project task sets, taxonomy structures, and web page link graphs, enabling sophisticated querying based on hierarchical relationships.
• Unmapped types in raw SQL queries: EF8 elevates raw SQL queries by enabling retrieval of any mappable CLR type sans inclusion in the EF model. Leveraging SqlQuery or SqlQueryRaw, EF8 enhances the execution of queries with unmapped types, ensuring parameterization and alignment with result sets.

The evolution from EF Core 7 to EF8 signifies a significant leap in capabilities, empowering developers with enhanced modeling, querying, and flexibility. With a comprehensive suite of enhancements, EF8 fortifies its position as a cornerstone in the realm of data access and management within the .NET ecosystem.
