This EF Core Mistake Is Wrecking Performance (Fix Inside)

Summary

Milan demonstrates optimizing an Entity Framework Core query by addressing a common performance issue when fetching data across microservices or external systems. The tutorial focuses on an invoice retrieval scenario where additional data must be loaded, revealing an inefficient approach of iterating and loading line items separately for each invoice. The practical takeaway is showing developers a method to significantly improve query performance by four times, which can be applied across various distributed communication and database interaction contexts.
