ASP.NET 2.0: unexpected exception after Page_Unload()

[RAM]

Hello,
I am learning .NET 2.0 and I have written simple application with
Default.aspx page and logging in Logon.aspx/Logon.aspx.cs.
After Page_Unload of Logon.aspx.cs (I have checked by debugging) I
receive error that I don't understand:

Message: Exception of type 'System.Web.HttpUnhandledException' was
thrown.
Stack: at System.Web.UI.Page.HandleError(Exception e) at

includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint)

System.Web.HttpApplication.CallHandlerExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute()

Boolean& completedSynchronously)
Source: System.Web

There's no error in my code - I have checked by debugging.
Please help. I cannot continue working.

Please, ensure that you call the base Page_Unload, that is the Page_Unload
of the parent class at the end of your Page_Unload: maybe some cleanup code
is not performed correctly.

Otherwise, send the code in you Page_Unload; it's quite impossible to
understand what's going on only from the stack trace.

Regards,
Paolo.

I added base.page_Load(), base.Page_unload() but it didn't help.

My Page_Load()/Page_Uload() are empty.
I attach mini-project.
