I needed to display the application version in a file based ASP.NET 3.5 application written in Visual Basic.  I wrote the following methods in my AssemblyInfo.vb file in the App_Code directory and it worked! Out popped the Version Number of 1.0.0.10 instead of that annoying 0.0.0.0. 

Imports System
Imports System.Reflection
Imports System.Runtime.InteropServices
