Version info in an About Box

I am a very new programmer....

I have an About Box that I generated using a Windows Forms Template.  Our build system for the product updates the AssemblyFile Version attribute in the GlobalAssemblyInfo.cs file.  I have been to many sites and have found the code to properly update the Details in the .exe Properties file to correctly display the product version, however, I have been unsuccessful at getting the version in the about box to display the same (and correct) version that the properties window is displaying.

My about box code is:

partial class AboutBox1 : Form
    {
        public AboutBox1()
        {
            InitializeComponent();
            this.Text = String.Format("About {0}", AssemblyTitle);
            this.labelProductName.Text = AssemblyProduct;
            this.labelVersion.Text = String.Format("Version {0}", AssemblyVersion);
            this.labelCopyright.Text = AssemblyCopyright;
            this.labelCompanyName.Text = AssemblyCompany;
            this.textBoxDescription.Text = AssemblyDescription;
        }

public string AssemblyVersion
        {
            get
            {
                return Assembly.GetExecutingAssembly().GetName().Version.ToString();
            }
        }

And my GlobalAssemblyInfo.cs file is:

using System.Reflection;
using System.Runtime.CompilerServices;
using System.Runtime.InteropServices;

// Global settings
[assembly: AssemblyConfiguration("RELEASE")]
[assembly: AssemblyCompany("xxxx")]
[assembly: AssemblyProduct("xxxx")]
[assembly: AssemblyCopyright("xxxx.")]
[assembly: AssemblyTrademark("")]
[assembly: AssemblyCulture("")]

[assembly: AssemblyVersion("2.0.*")]
[assembly: AssemblyFileVersion("2.0.*")]

I have made sure that the AssemblyInfo.cs file does not contain any of the information that is in GlobalAssemblyInfo.cs.

I have tried changing the AboutBox1.cs file to have AssemblyFileVersion instead of AssemblyVersion but that didn't work.

What am I missing?
