How does the skill manage database migrations?

It enforces a strict CLI-only workflow to prevent schema drift and provides a dedicated worker service pattern for running migrations safely during deployment.

How does it handle database connection failures?

It utilizes the EF Core ExecutionStrategy to automatically retry operations that fail due to transient network or database issues, increasing application reliability.

Why does this skill recommend NoTracking by default?

Using NoTracking by default significantly improves performance and reduces memory overhead for read-only queries, which constitute the majority of web API traffic.

Is this skill compatible with .NET Aspire?

Yes, it includes specific implementation patterns for orchestrating migration services and database dependencies within the .NET Aspire AppHost.

Does it support high-performance bulk updates?

Yes, it promotes the use of ExecuteUpdate and ExecuteDelete (introduced in EF Core 7) for executing batch changes directly in the database without loading entities into memory.

Implements high-performance Entity Framework Core patterns, migration workflows, and database resiliency strategies for .NET applications.

This skill provides a comprehensive architectural framework for .NET developers using Entity Framework Core, focusing on performance optimization through NoTracking defaults and efficient query splitting. It establishes robust standards for database lifecycle management by enforcing CLI-only migration workflows and providing a dedicated Migration Service pattern ideal for .NET Aspire environments. By integrating execution strategies for transient failures and promoting modern bulk operations, it helps teams build scalable, resilient, and maintainable data access layers while avoiding common EF Core pitfalls.
