+# Using Dapper with the ABP Framework
+
+[Dapper](https://github.com/DapperLib/Dapper) is a simple and lightweight object mapper for .NET. A key feature of Dapper is its [high performance](https://github.com/DapperLib/Dapper#performance) compared to other ORMs. In this article, I will show how to use it in your ABP projects.
+
+## When to use Dapper?
+
+In ABP Framework, we suggest to use Dapper in a combination with Entity Framework Core (EF Core) for the following reasons:
+
+* EF Core is much easier to use (you don't need to manually write SQL queries for example)
+* EF Core abstracts different DBMS dialects, so it will be easier to change your DBMS later.
+* EF Core is better compatible with Object Oriented Programming (OOP) practices and is more type safe to work with. So, EF Core code is more understandable and maintainable.
+
+In most of your use cases, you typically work with one or a few entities where the performance doesn't make much difference. However, there may be certain places in your application where it matters:
+
+* You may work with a lot of entities, so want to query faster.
+* You may be performing too many database operations in a single request.
+* EF Core may not create an optimized SQL query and you may want to manually write it for a better performance.
+
+In such cases, performance can be critical. Dapper can be a good choice if you want to easily write SQL queries and bind the result to your objects.
