Basics To Advanced 1-to-1 Self Referencing Table: EF Core, SQL & Fluent API
Do you know how a single SQL table references itself under the hood? In Part 1 of this Advanced Entity Framework Core (EF Core) Masterclass, we are dissecting 1-to-1 Self-Referencing Tables from a Senior Software Architect's perspective.
We won’t just write C# properties. We will dive deep into how the EF Core ChangeTracker works in memory, how SQL Server physically stores this data on disk, and why making a primitive integer nullable (int?) is 100% mandatory for your root-level records.
🚀 What You Will Learn in Part 1:
What exactly is a Self-Referencing Table in relational databases?
Designing a Strict 1-to-1 Mentorship relationship (Mentor & Mentee).
The Danger of Non-Nullable Foreign Keys (The DBA Trick vs. Runtime Crash).
Why the EF Core ChangeTracker requires an 'int?' for the first root-level record.
Memory Isolation: C# Reference Navigation Properties vs. SQL Physical Foreign Keys.
