Extra properties stored in separate fields in the database are known as **Shadow Properties**. These properties are not defined in the entity class, but are part of the EF Core model and can be referenced in LINQ queries using the EF.Property static method
```csharp
var query = (await GetQueryableAsync()).Where(x => EF.Property<string>(x, "Title") == "MyTitle");
```
