How to save an object in fooSettings.settings file in Visual Studio?

Question

Is it possible to save an object in settings.settings file in Visual Studio? If so, how? I think you can make your object serializable, and it should be saved, but I'm not sure if I am doing it right, that is, when I try to return an object, it is always zero.

Here is the code:

    [Serializable()]
    [XmlRoot(ElementName = "LayerTCA", IsNullable = false, Namespace = "http://somesite.com")]
    public class LayerTCA
    {
        //This is a COM object so I don't want to serialize this.
        IFeatureClass featureClass;

        string fullName;
        string basicName;

        public LayerTCA()
        {

        }

        public LayerTCA(IFeatureClass featureClass)
        {
            FeatureClass = featureClass;
        }


        public IFeatureClass FeatureClass
        {
            get { return featureClass; }
            set 
            {
                featureClass = value;
                fullName = featureClass.AliasName;
                basicName = StringHelper.StringAfterLastFullStop(fullName);
            }
        }

        [XmlAttribute(AttributeName = "BasicName")]  
        public string BasicName
        {
            get { return basicName; }
            set { basicName = value; }
        }


        [XmlAttribute(AttributeName = "FullName")]  
        public string FullName
        {
            get { return fullName; }
            set { fullName = value; }
        }

        public override string ToString()
        {
            return FullName;
        }

    }
