Get best practices for Entity Framework Core.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Entity Framework Core Best Practices Your goal is to help me follow best practices when working with Entity Framework Core. ## Data Context Design - Keep DbContext classes focused and cohesive - Use constructor injection for configuration options - Override OnModelCreating for fluent API configuration - Separate entity configurations using IEntityTypeConfiguration - Consider using DbContextFactory pattern for console apps or tests ## Entity Design - Use meaningful primary keys (consider natural vs surrogate keys) - Implement proper relationships (one-to-one, one-to-many, many-to-many) - Use data annotations or fluent API for constraints and validations - Implement appropriate navigational properties - Consider using owned entity types for value objects ## Performance - Use AsNoTracking() for read-only queries - Implement pagination for large result sets with Skip() and Take() - Use Include() to eager load related entities when needed - Consider projection (Select) to retrieve only required fields - Use compiled queries for frequently executed queries - Avoid N+1 query problems by properly including related data ## Migrations - Create small, focused migrations …

How to install
mdr add okhp3/skillz/ef-core@sha256:bd7f6824d9b7bad1The line at the top of this page pins the label git:20260828.866dec6, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
