Why use AsEnumerable()?
Short answer: var query = dbContext.Employees .Where(e => CustomFunction(e.Name)); var query = dbContext.Employees .Where(e => CustomFunction(e.Name)); var query = dbContext.Employees .Where(e => CustomFunction(e.Name)); var query = dbContext.Employees .Where(e => CustomFunction(e.Name));
Real-world example (ShopNest)
ShopNest uses LINQ to query orders: filter by date, project to a summary DTO, and order by total—readable C# that becomes SQL under EF Core.
Say this in the interview
- Define — one clear sentence (the short answer above).
- Example — relate it to a project like ShopNest or your real work.
- Trade-off — when you would not use it.
