Accessing Version Number in .Net

Q: How do I programatically access the version number of an ASP.Net application?

A: The version number, and other general information, is kept in the AssemblyInfo.vb (for VB.Net projects). All information is housed in attributes in the file, as listed below:

Assembly: AssemblyTitle("MyApp")
Assembly: AssemblyDescription("A Sample Program")
Assembly: AssemblyCompany("ABC Software Corp.")
Assembly: AssemblyProduct("")
Assembly: AssemblyCopyright("2006")
Assembly: AssemblyTrademark("")
Assembly: CLSCompliant(True)
Assembly: AssemblyVersion("2.0.*")

To access the application version through .Net code, use
System.Reflection.Assembly.GetExecutingAssembly().GetName().Version.ToString(). The value displayed will be 4 sets of numbers, separated by '.' (similar to TCP/IP address). The version information for an assembly consists of the following four values:
Major Version
Minor Version
Build Number
