Reading Assembly version information of WPF application

I am reading version information of my wpf application, but I am not getting the correct version as I have write in AssemblyInfo.cs file. In my file there is

[assembly: AssemblyVersion("0.1.001")]
[assembly: AssemblyFileVersion("0.0.001")]

I am reading version information using this code

 System.Reflection.Assembly.GetExecutingAssembly().GetName().Version.ToString();

I am getting this version 0.1.1.0 and it should be 0.1.001

Thanks
