What is Dapper?
A micro-ORM for .NET that extends ADO.NET connections to execute SQL queries and stored procedures, supporting both synchronous and asynchronous operations with features for object mapping, dynamic SQL building, and multi-result set processing.

The Vioscale score: one lens on the evidence
Not user reviews and not a paid placement: a confidence-weighted blend of the independent signals below (adoption, activity, security posture, and more), which you can sort and re-weight yourself. Vendors can correct their listing but can never move their rank, and stars are weighted low as a vanity metric. It is one way to read the evidence for Dapper, not the verdict.
