[ModApi] exception throw on IMyLandingGear.LockModeChanged event handler registry

Sisk S'jet shared this bug 4 years ago

When we try to register an event handler for IMyLandingGear.LockModeChanged, an exception is thrown:

Cannot bind to the target method because its signature or security transparency is not compatible with that of the delegate type.
Testing code:

using Sandbox.Common.ObjectBuilders;
using SpaceEngineers.Game.ModAPI;
using VRage.Game.Components;
using VRage.ModAPI;
using VRage.ObjectBuilders;

namespace Test {
    [MyEntityComponentDescriptor(typeof(MyObjectBuilder_LandingGear), false)]
    public class LandingGearLogic : MyGameLogicComponent {
        private IMyLandingGear _landingGear;

        public override void Close() {
            _landingGear.LockModeChanged -= OnLockModeChanged;

        public override void Init(MyObjectBuilder_EntityBase objectBuilder) {
            _landingGear = Entity as IMyLandingGear;
            NeedsUpdate = MyEntityUpdateEnum.BEFORE_NEXT_FRAME;

        public override void UpdateOnceBeforeFrame() {
            _landingGear.LockModeChanged += OnLockModeChanged;

        private void OnLockModeChanged(IMyLandingGear gear, SpaceEngineers.Game.ModAPI.Ingame.LandingGearMode mode) { }

This also happens when trying to hook the AttachedEntityChanged event for IMyMotorStator and IMyPistonBase. Same error.
