Recently, I joined an organization where they are using Dapper instead of Entity Framework. I haven’t worked with Dapper before, so I would appreciate some guidance on the important Dapper concepts I should learn in a short period of time. I also want to improve my performance and productivity while working on the project.

Hi Soheb Ahmad,
Dapper and Entity Framework (EF) are .NET libraries for data access.
Dapper:
It is micro ORM (Object Relational Mapper).
It's performance is extremely fast and lightweight, with performance close to raw ADO.NET.
It is used to write SQL queries by hand. It simply maps query results to your C# objects.
It provides minimal abstraction through giving direct control over SQL.
There is no change tracking, caching, or migration support.
There is no LINQ-to-SQL and need to use raw SQL or stored procedures.
It is best option for high performance scenarios, applications where you want full control over your SQL, simple data access layers.
Entity Framework (EF Core):
It is full fledged ORM.
It's performance is slower than Dapper due to extra abstraction, change tracking, LINQ parsing, but very productive for many apps.
It is used to work with strongly-typed C# classes and LINQ queries, and EF generates SQL automatically.
It supports change tracking, caching and lazy loading.
It automatic database generation and schema migrations.
It is LINQ-to-Entities for strongly typed, database-agnostic queries.
It supports multiple database providers (SQL Server, PostgreSQL, etc.)
it is best for applications with complex domain models, need for rapid development, maintainable code, and database schema evolution.
Summary
Dapper is best option when one wants to speed and hand-crafted SQL with minimal overhead.
Entity Framework is recommended for most enterprise apps where productivity, maintainability, and features like migrations and change tracking matter more than raw performance.
Glad to help! Please mark this answer as the accepted answer if it helped you out!

Dapper is a lightweight micro-ORM that provides high performance and minimal overhead, but unlike Entity Framework, it does not provide features such as change tracking, automatic migrations, or LINQ-based query generation. As a result, developers are expected to write and optimize SQL queries directly.
To become productive quickly, I would recommend focusing on the following areas:
Basic CRUD operations (SELECT, INSERT, UPDATE, DELETE) using Dapper.
Parameterized queries to prevent SQL injection and improve maintainability.
Object mapping between query results and C# classes.
Executing stored procedures, including handling input and output parameters.
Working with joins and Dapper's multi-mapping capabilities for related entities.
Using transactions to ensure data consistency.
Asynchronous methods for scalable and performant applications.
Handling multiple result sets efficiently.
Proper database connection management and dependency injection patterns.
SQL performance tuning, indexing, and query optimization.
The biggest difference from Entity Framework is that Dapper gives you full control over the SQL being executed. Because of this, strong SQL knowledge becomes much more important than learning Dapper-specific APIs. In fact, developers who already have good SQL skills can usually become productive with Dapper in a very short time.
My suggestion would be to start by understanding the existing repository and data access patterns used in your project, review how queries are written, and spend some time strengthening your SQL skills. This will have a much greater impact on your performance and productivity than focusing only on Dapper itself.
Overall, Dapper is relatively small and easy to learn. The real key to success is becoming comfortable with writing efficient SQL and understanding how the application's data access layer is structured.
