Entity Framework VS Entity Framework Core

• Productivity
  Entity Framework automates database-related code generation, reducing the amount of boilerplate code developers must write and maintain. This allows developers to work more efficiently and focus more on business logic.
• Abstraction
  It abstracts the database interaction details, enabling developers to work with higher-level .NET objects instead of raw SQL queries, resulting in clearer and more manageable code.
• Code First Approach
  This allows developers to define their database schema using C# classes, making it easy to evolve the database alongside the codebase using migrations.
• Support for Multiple Databases
  Entity Framework supports a wide range of relational databases, including SQL Server, PostgreSQL, SQLite, and MySQL, providing flexibility and choice to the developers.
• Change Tracking
  It provides automatic change tracking of entity objects, simplifying the process of updating data in the database without manually tracking object changes.

Possible disadvantages

• Performance Overhead
  The abstraction layer can lead to performance overhead compared to plain SQL queries, as the generated queries might not be as optimized as handcrafted SQL.
• Complexity
  For simple or small applications, the complexity introduced by using an ORM like Entity Framework might be unnecessary and could complicate the architecture.
• Learning Curve
  Developers need to learn the specific concepts and configurations of Entity Framework, which can be time-consuming compared to traditional database access methodologies.
• Debugging Difficulty
  Debugging issues can be more challenging because of the abstraction, making it sometimes difficult to trace the exact query being executed and pinpoint performance bottlenecks.
• Limited SQL Features
  While Entity Framework supports a wide range of SQL functionalities, there are advanced features specific to certain databases that may not be fully supported or could require custom implementation.

• Cross-Platform Support
  Entity Framework Core is built to work across multiple platforms, allowing developers to build applications for Windows, Linux, and macOS with the same data access layer.
• Code-First Approach
  Entity Framework Core supports a code-first approach, enabling developers to define their model using C# classes and then generate a database schema from these models. This is particularly useful for agile development and domain-driven design.
• Rich LINQ Support
  It provides robust LINQ support, allowing developers to write queries in a type-safe manner while leveraging the full expressive power of LINQ for querying databases.
• Performance Improvements
  Compared to its predecessor, Entity Framework Core has several performance enhancements, including optimized query compilation and reduced memory allocations.
• Migration Support
  It includes a migrations feature that enables developers to evolve the database schema over time without losing existing data, allowing for smooth iterative development.

Possible disadvantages

• Limited Features Compared to EF6
  Entity Framework Core, while improving over time, still lacks some features that were available in Entity Framework 6, such as automatic lazy loading and certain advanced data modeling capabilities.
• Steep Learning Curve
  For developers who are new to ORMs or coming from other database management techniques, getting accustomed to all features and configurations in Entity Framework Core can be challenging.
• Complex Configuration
  Sometimes configuring Entity Framework Core, especially for complex applications requiring detailed customizations, can lead to increased complexity and overhead.
• Dependency on .NET Core Ecosystem
  Entity Framework Core is tightly coupled with the .NET Core ecosystem, which might require additional considerations or adjustments for projects not initially developed in this environment.
• Community and Documentation Maturity
  Though growing, the community support and documentation may not be as mature as some more established ORM solutions, occasionally leading to difficulties in finding help or examples.
