How to determine if a running ASP.NET App was compiled in Debug or Release Mode?

Recently there was a dotnet.framework.aspnet newsgroup post on this subject. I answered it, but my answer wasn't complete. Here is a short example of how you can definitively tell - AT RUNTIME - if the assembly was built in Debug or Release mode:

// in AssemblyInfo.cs:
[assembly: AssemblyConfiguration("Debug")]
[assembly: AssemblyConfiguration("Release")]

private string buildMode=String.Empty;
private void Page_Load(object sender, System.EventArgs e)
Assembly asm = Assembly.GetExecutingAssembly();
object[] objArray=asm.GetCustomAttributes(false) ;
foreach (object obj in objArray)
AssemblyConfigurationAttribute conf =
obj as AssemblyConfigurationAttribute;
if (conf != null)
this.buildMode=conf.Configuration ;
Response.Write("Build Mode: " +this.buildMode);

On a lighter note, you just gotta weep to see this on Microsoft's security pages :
