I'm getting a NullReferenceException (VB.Net) and don't see where it could be coming from (dev with 15+ years of experience perhaps having a 'moment')

None of the parameters are empty/null/nothing

auditAuthSuccess(UserName, olaHelper.batchID, olaHelper.authenticatedStudentIDSite)  '<-- I put a break on this line

Code execution halts there and I have no indications of an exception in my output window.

The signature for the auditAuthSuccess method is:

Public Shared Sub auditAuthSuccess(ByVal managementUserName As String, ByVal batchID As String, ByVal studentID As String)
        fooBar() '<-- I put a break here also and code halts as expected, but there's a NullReferenceException in the output window now
End Sub

When code is halted on the line calling fooBar(), the Call Stack shows:

OLAWeb.DLL!Comptek.OLA.olaHelper.auditAuthSuccess(String managementUserName, String batchID, String studentID) Line 467 Basic

OLAWeb.DLL!Comptek.OLA.frmLogin.FinishLogin(System.Web.UI.WebControls.AuthenticateEventArg开发者_高级运维s e, String UserName, String Password, String RedirectAddress, String strRoles) Line 234 + 0xc5 bytes Basic

No unmanaged code, no other methods, etc.. So were in the world is the NullReferenceException coming from?

Perhaps you can try to switch on the Visual Studio runtime exception info: Visual Studio > Debug > Exeptions > Common Language Runtime Exceptions > Thrown = YES.
