Entity Framework Core features and specs

• 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 of Entity Framework Core

• 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.

Dapper features and specs

• Performance
  Dapper is known for its high performance as it uses raw SQL queries and maps results directly to objects, which reduces the overhead of ORM frameworks.
• Lightweight
  It is a micro ORM and thus does not add significant weight to the application. It only requires a single DLL, which is simple to integrate.
• Flexibility
  Dapper provides the flexibility to write complex queries and take full advantage of SQL features, performing tasks that are cumbersome with full ORMs.
• Easy Mapping
  Allows easy mapping of data from the database to C# objects, helping developers handle the conversion between the two seamlessly.
• Open Source and Support
  Dapper is open-source and has a strong community support with regular updates and a wealth of resources available for learning and troubleshooting.

Possible disadvantages of Dapper

• Lack of Built-in Features
  As a micro ORM, Dapper lacks some of the advanced features present in full-featured ORMs like Entity Framework, such as change tracking and full LINQ support.
• Manual SQL Queries
  Developers need to write SQL queries manually, which can increase the risk of SQL injection and bugs if not handled carefully.
• No Automatic Migration
  Unlike some ORMs, Dapper does not offer automatic database migration capabilities, requiring developers to handle schema changes separately.
• Limited Database Support
  While Dapper supports many popular databases, it may not support niche databases or specific features that are easily managed by other ORMs.
