Entity Framework Profiler (EF Prof) is a desktop diagnostic tool designed to analyze database activity generated by applications using Microsoft Entity Framework. It provides visibility into SQL queries, transactions and data access behavior produced by the ORM layer. The tool captures and displays database commands in real time, allowing developers to inspect generated SQL statements, execution times, and transactional boundaries. It helps identify inefficient query patterns, excessive round-trips, and common ORM-related issues such as N+1 queries or over-fetching data. EF Prof operates externally to the application and does not require intrusive code changes. It is used during development, testing and troubleshooting to understand how Entity Framework translates LINQ expressions and object operations into SQL commands. The primary goal of EF Prof is to improve database performance, reduce latency, and ensure efficient use of database resources in applications built on Entity Framework.
