GetProjectedProperties()

Collects the set of IProperty that this query's projection actually reads, so that it can be pushed down to the storage layer to skip deserialization of properties that aren't needed (see the projection push-down design). Must be called before ApplyProjection(): that method destructively rewrites MASES.EntityFrameworkCore.KNet.Query.Internal.KEFCoreQueryExpression._projectionMapping/MASES.EntityFrameworkCore.KNet.Query.Internal.KEFCoreQueryExpression._clientProjections into plain ValueBuffer indices, erasing the IProperty information this method relies on.

public virtual IReadOnlyList<IProperty>? GetProjectedProperties()

Returns

IReadOnlyList<IProperty>

The properties actually read by the projection, or null when no safe narrowing can be determined — e.g. when a projection element is bound to a whole EntityProjectionExpression (the query returns entire entities: .Select(x => x), context.Set<T>(), or an owned/complex sub-object still expressed as a full entity projection — all properties are genuinely needed), when a property can't be inferred from a projected expression (e.g. a computed expression, a bound complex-type projection, or any shape other than a direct property read), or when the query has no property-level shape to narrow at all (e.g. Count()/Any()). null means "use the full entity, no filtering" — the safe default whenever the projection shape isn't unambiguously recognized.
