• I wanted to include the build date in an "about" form for a Windows desktop application.  Below is code to get the build date of the application.
  
  ' Get Build Date information.

Dim _ExecutingAssemblyName As String = Assembly.GetExecutingAssembly.GetName().Name
Dim _ExecutingAssembly As Assembly = Assembly.GetExecutingAssembly

Try
  Dim _buildDate As Date = File.GetLastWriteTime(_ExecutingAssembly.Location)
  lblBuildDate.Text = lblBuildDate.Text + " " + _ExecutingAssemblyName + ", " + _buildDate.ToString
Catch
  lblBuildDate.Text = " Error trying to find Build Date."
EndTry
