How do I handle tombstoning when using MvxReference.Strong

Understanding `MvxReference.Strong`

`MvxReference.Strong` is likely used to maintain strong references to objects in your application. Strong references prevent the garbage collector from freeing the memory occupied by an object until the reference is explicitly set to `null` or goes out of scope.

Handling Potential Issues

1. Avoid Circular References: Ensure that your objects do not hold circular references to each other. This can prevent garbage collection and lead to memory leaks. Use weak references (`WeakReference` in .NET) where possible to break such cycles.

2. Proper Disposal: When using strong references, make sure to explicitly set them to `null` when they are no longer needed. This allows the garbage collector to reclaim the memory.

3. Use Weak References When Appropriate: Consider using `MvxReference.Weak` or similar constructs if available, to allow for garbage collection when the referenced object is no longer needed.

4. Monitor Memory Usage: Use profiling tools to monitor your application's memory usage and identify potential leaks or issues related to strong references.

5. Implement IDisposable: If your objects hold unmanaged resources, implement `IDisposable` to ensure these resources are properly released when no longer needed.

6. Avoid Overuse of Strong References: Only use strong references when necessary. Overuse can lead to memory issues if not managed properly.

Example of Managing References

Here's a simple example of how you might manage strong references in a class:

csharp
public class MyClass
{
    private MvxReference.Strong _myObject;

    public MyClass()
    {
        _myObject = new MvxReference.Strong(new MyObject());
    }

    public void Cleanup()
    {
        _myObject = null; // Release the strong reference
    }
}

In this example, `Cleanup` is used to release the strong reference when it's no longer needed.

If you're experiencing specific issues with tombstoning in a different context (e.g., Cassandra or PCB design), the strategies would be different:

- Cassandra Tombstones: Avoid inserting `NULL` values directly, as they create tombstones. Instead, use special values or avoid including columns with `NULL` values in your inserts.

- PCB Tombstoning: Ensure proper soldering and component placement during assembly to prevent components from lifting off their pads.
