CC0029 should only apply if the class has a finalizer

[AridTag]

Version 1.1.0

The CC0029 warning should only show up if the class implementing IDisposable contains a finalizer itself.

MSDN Remarks on GC.SuppressFinalize

If obj does not have a finalizer, the call to the SuppressFinalize method has no effect.

In this example our class owns an IDisposable that may itself have a finalizer but we don't need to know that. Our example class is disposing the disposable and has no finalizer itself.

public class Example : IDisposable
{
    private bool _IsDisposed;
    private IDisposable _SomeDisposable;

    public Example(IDisposable someDisposable)
    {
        _SomeDisposable = someDisposable;
    }

    public void Dispose()
    {
        Dispose(true);
    }

    private void Dispose(bool disposing)
    {
        if (!_IsDisposed)
        {
            if (disposing)
            {
                if (_SomeDisposable != null)
                {
                    _SomeDisposable.Dispose();
                    _SomeDisposable = null;
                }
            }
        }
        _IsDisposed = true;
    }
}
