Should I use Repository pattern with Dapper?

Large-scale, complex projects benefit the most from readability improvments, and when using Dapper and C# the Dapper Base Repository pattern allows for better code readability and a single point of failure by creating a base class with generic methods that allow for querying and execution against a SQL database.

How do I use Dapper with Repository pattern?

Let us define interface first: Bootstrap code for repository class has the responsibility to create SqlConnection object and open the connection to database. After that, Dapper will utilize this connection to execute SQL queries against database. Make sure you have connection string named MainDb.

What is the difference between Dapper and Entity Framework?

Dapper describes itself as “micro-ORM” because it provides much less functionality than Entity Framework does. Further, out of the box, Dapper supports only querying and updating through raw SQL, does not support configuring classes to match database tables, and doesn’t support code-first development.

Does Dapper work with .NET core?

Should I use EF core or Dapper?

Dapper is literally much faster than Entity Framework Core considering the fact that there are no bells and whistles in Dapper. It is a straight forward Micro ORM that has minimal features as well. Dapper is heaven for those who still like to work with RAW Queries rather than LINQ with EFCore.

Can we use Dapper and EF core in same project?

Since Dapper is just working on extension methods, you can use it for the performance-sensitive areas of your code. And you can continue to use EF for other areas of your code. The queries that you have that are still using EF will not be as fast – but at least the queries using Dapper will be faster.

Should I use Dapper or Entity Framework?

Dapper is super awesome to handle complex queries that sport multiple joins and some real long business logic. Entity Framework Core is great for class generation, object tracking, mapping to multiple nested classes, and quite a lot more. So it’s usually Performance and Features when talking about these 2 ORMs.

How to implement unit of work pattern with Dapper?

The “transaction” is the db implementation, the “unit of work” is more of a higher level conceptual thing. If we had more persistence that just one database, there would be a difference, and the UOW would contain more than just one transaction. So, to avoid confusion, “Transaction” is probably not a great word to use in our UOW interface.

Why is dapper in ASP.NET Core 3.1?

This is possible because Dapper works directly with the RAW SQL and hence the time-delay is quite less. This boosts the performance of Dapper. We’ll build a simple ASP.NET Core 3.1 WebAPI following a Clean Architecture , Repository Pattern and Unit of Work.

How are repository methods usually transactional in Dapper?

Repository methods are usually transactional, and according to your question, you’re using Dapper, so maintaining transactional consistency can be done per method call (not based on state as with the UoW). The Dispose () is implicit to the using and you’ve neutralized your issue.

Which is faster to query Dapper or Entity Framework?

It’s more like an Automapper for the SQL World. This powerful ORM was build by the folks at StackOverflow and is definitely faster at querying data when compared to the performance of Entity Framework. This is possible because Dapper works directly with the RAW SQL and hence the time-delay is quite less. This boosts the performance of Dapper.
