dotnet-efcore-architecture

Strategic architectural patterns for EF Core data layers. Covers read/write model separation, aggregate boundary design, repository vs direct DbContext policy, N+1 query governance, row limit enforcement, and projection patterns. These patterns guide how to structure a data layer -- not how to write individual queries (see [skill:dotnet-efcore-patterns] for tactical usage).

Scope

• Read/write model separation and CQRS patterns
• Aggregate boundary design and repository policy
• N+1 query governance and row limit enforcement
• Projection patterns and query optimization strategy

Out of scope

• Tactical EF Core usage (DbContext lifecycle, AsNoTracking, migrations, interceptors) -- see [skill:dotnet-efcore-patterns]
• Data access technology selection (EF Core vs Dapper vs ADO.NET) -- see [skill:dotnet-data-access-strategy]
• DI container mechanics -- see [skill:dotnet-csharp-dependency-injection]
• Async patterns -- see [skill:dotnet-csharp-async-patterns]
• Integration testing data layers -- see [skill:dotnet-integration-testing]
