Abstract
When using Entity Framework Core for data access, all database exceptions are wrapped in DbUpdateException. If you need to know whether the exception was caused by a unique constraint, the value being too long, or the value missing for a required column, you need to dig into the concrete DbException subclass instance and check the error number to determine the exact cause. In this episode, learn how EntityFramework.Exceptions handles all the database-specific details and allows you to use typed exceptions for Entity Framework Core when your query violates database constraints.

Backend Engineer & Software Architect · 3x Microsoft MVP · International Speaker

I’m a backend engineer and software architect with 17+ years of .NET, mostly in banking and fintech: payment and transaction processing, public APIs, and the internal platforms other teams build on. I’ve led teams and a platform unit, and I stay hands-on in the code, increasingly through AI coding agents like Claude Code and Codex.

Alongside that, I build open-source .NET libraries and developer tools with 45M+ NuGet downloads: DuckDB.NET, EntityFramework.Exceptions, EFCore.Visualizer and others. That work sits where .NET meets the database: native interop, Native AOT extensions for DuckDB and PostgreSQL, and tooling that makes query plans easier to debug. I also speak about .NET and databases at conferences like NDC, KCDC and .NET Conf.
