Fixes #18265

                shaperExpression = unaryExpression.Operand as EntityShaperExpression;

This should also check NodeType of UnaryExpression. (Assuming only convert is allowed)

            case ProjectionBindingExpression innerProjectionBindingExpression:

This assumes that projectionBinding is always mapped by Index. Is that always true? Can it not be projection mapping? #WontFix

                innerEntityProjection = (EntityProjectionExpression)((UnaryExpression)unaryExpression.Operand).Operand;

Should there be type safety check? Or we have invariant in pipeline for this? #WontFix

                        else if (projectionExpression is UnaryExpression convertExpression)

Also check nodeType?

                        var projectionExpression = ((UnaryExpression)binaryExpression.Right).Operand;

Another invariant? #Resolved

            case ProjectionBindingExpression innerProjectionBindingExpression:

For now Member would only be called in an Index projectionBinding, I think we would only need projection mapping if we allow querying unmapped properties unless you can think of a different case off top of your head.

                innerEntityProjection = (EntityProjectionExpression)((UnaryExpression)unaryExpression.Operand).Operand;

This is an invariant - we always need to cast the projection to ValueBuffer and we only support Member on entity projection. I guess we could throw a better exception message if it's not, but I would need to think to come up with a test case.
