Webpart custom properties

Scenario:
I use lot of configurable properties in my Webpart.

Always end in spending 5-10 min to make it work because of stupid Microsoft article ( Creating a Web Part with Custom Properties ) , which always shows up as number 1 result when you google, which talk about WebPart inherited from Microsoft.SharePoint.WebPartPages.WebPart class

Solution:
Here's the 100% right way to do it.

Code:

using System.ComponentModel;

using System.Web.UI.WebControls.WebParts;

namespace MyClient
{
    public class NewWP : System.Web.UI.WebControls.WebParts.WebPart
    {

private const string const_configuationListName = "xConfigurationMasterList";
        private string m_configuationListName = const_configuationListName;

        // Configuration List Name property.
        [Personalizable(PersonalizationScope.Shared)]
        [WebBrowsable(true)]
        [Category("Custom Properties")]
        [WebDisplayName("Configuration List Name")]
        [Description("Configuration List Name")]
        [DefaultValue(const_configuationListName)]
        public string ConfigurationListName
        {
            get
            {
                return m_configuationListName;
            }

            set
            {
                m_configuationListName = value;
            }
        }

...

 }
}
