Your Database Column Is Encrypted. Your JSON Response Isn't.
An EF Core value converter can encrypt a database column before it reaches storage, but the entity comes back as ordinary C# strings the moment the application reads it — and System.Text.Json serializes those values exactly like everything else. Here's how a JsonTypeInfo modifier encrypts specific properties at the serialization boundary with AES-GCM, without touching the domain model or the database mapping, and where this control helps, where it doesn't, and why it has to work alongside data minimization and log redaction, not replace them.

.NET Data Community Standup: Teach your AI agent database design with T-SQL static code analysis
Erik will show two ways you can take advantage of the open-source set of T-SQL static analysis rules, and the surrounding set of tools, that he maintains. First, you can get live code analysis of your SQL scripts as you type them in VS Code, Visual Studio and SQL Server Management Studio. Secondly, in companionship with EF Core Power Tools, you can build your database model (and EF Core model) with AI and guide it by enforcing the more than 140 rules in the package. 🎙️ Featuring: Jiri Cincura, Erik Ejlskov Jensen #net #data #efcore #tsql #vs #vscode #ssms

BOLA in ASP.NET Core: Why Authenticated Users Can Still Read Someone Else's Data
Broken Object Level Authorization (BOLA) is OWASP's #1 API security risk, and [Authorize] does nothing to stop it: it confirms who the caller is, not whether they should see the object behind this specific ID. Here's how BOLA shows up in ASP.NET Core APIs, why EF Core global query filters aren't a full fix on their own, and how to close it with resource-based authorization and a test matrix that catches the regression before a pentest does.
