Stack Overflow's Dapper rescues .NET devs from Entity Framework's production surprises: Finally, SQL control without the mystery bloat

Dapper, a micro Object-Relational Mapper, was created by the team at Stack Overflow to address performance issues with LINQ-to-SQL and early ORMs. It is a lightweight, opinionated, and minimal tool that executes SQL queries and maps results to objects without generating SQL or tracking entities. Dapper is ideal for teams that value control and performance, allowing developers to write their own SQL queries and providing predictable execution plans. The tool is widely used in the.NET ecosystem, particularly in legacy systems, and supports various databases including SQL Server, PostgreSQL, and MySQL. Dapper's simplicity and speed have made it a popular choice for high-throughput APIs, read-heavy CQRS read models, and batch processing. With its ability to coexist with existing ORMs, Dapper is a reliable tool for developers who need predictability at scale, making it an essential component in the.NET ecosystem, especially for those working with large datasets and legacy systems.
