Selecting just the necessary columns reduces the data retrieved and boosts query performance, optimizing efficiency levels.

3. Embracing FirstOrDefault Over SingleOrDefault Wisely

Loading code snippet...

FirstOrDefault is often a faster choice compared to SingleOrDefault, especially when working with extensive datasets.

4. Mindful Execution of Eager Loading Strategies

Loading code snippet...

Utilize Include for eager loading related entities selectively, avoiding unnecessary data retrieval problems and ensuring optimal performance.

5. Mitigating N+1 Query Issue via Intelligent Loading

Loading code snippet...

Use Include or Load to look for related entities in a single query, effectively combating the N+1 query problem and enhancing query efficiency.

6. Strategically Implement Batching for Updates and Inserts

Loading code snippet...

Batching updates and inserts can significantly reduce round trips to the database, optimizing performance when dealing with bulk operations.

7. Harnessing the Perks of Compiled Queries

Loading code snippet...

Compiled queries offer a performance boost by pre-compiling LINQ queries, enhancing efficiency and speed during execution.

8. Mastering the Art of Using ToList Wisely

Avoid premature materialization by deferring the use of ToList until the final moments of code execution, enabling optimized query performance.

9. Implementing Take and Skip for Enhanced Paging Functionality
