In the .NET world, Entity Framework Core and Dapper are the industry standards. However, many less popular tools are also used in real-world projects. RepoDB and SqlSugar are among these ORMs.

In this article, we'll look at them through the lens of PVS-Studio static analyzer. Instead of comparing API capabilities or performance, we'll check the projects' source code for potential bugs and suspicious constructs.

Despite the substantial amount of code and extensive functionality of the projects, the analysis revealed only a few suspicious code fragments. This suggests that both projects are well written and maintained at a high standard.
