GD0106: The exported property is an explicit interface implementation

Rule ID	GD0106
Category	Usage
Fix is breaking or non-breaking	Non-breaking
Enabled by default	Yes

Cause

An explicit interface property implementation is annotated with the [Export] attribute. Properties that implement an interface explicitly can't be exported.

Rule description

Redot doesn't allow exporting explicit interface property implementations. When an interface member is implemented explicitly, the member is hidden and consumers can't access them unless the type is converted to the interface first. Explicitly implemented members can also share the same name of other members in the type, so it could create naming conflicts with other exported members.

public interface MyInterface
{
    public int MyProperty { get; set; }
}

public class MyNode1 : Node, MyInterface
{
    // The property can be exported because it implements the interface implicitly.
    [Export]
    public int MyProperty { get; set; }
}

public class MyNode2 : Node, MyInterface
{
    // The property can't be exported because it implements the interface explicitly.
    [Export]
    int MyInterface.MyProperty { get; set; }
}

How to fix violations

To fix a violation of this rule, implement the interface implicitly or remove the [Export] attribute.

When to suppress warnings

Do not suppress a warning from this rule. Explicit interface property implementations can't be exported so they will be ignored by Redot, resulting in runtime errors.
