My last blog post was about a feature in SQL Server called Row Level Security Policy. It’s quite simple and known feature for people who’re working directly with databases. But most .NET developers are using ORM of some kind to work with DB, and some of them tend to be blind to stuff that is not available through object model in an easy way. And since Entity Framework is most popular ORM in C# environment and my ORM of choice in most cases, I’ll show you how to use RLS in it.
