Modifica di Desktop Remoto e Just-in-time debugging

Il '''Just-in-time debugging''' entra in funzione quando un programma .NET smette di funzionare. ''Per qualche motivo (da indagare)'', talvolta questo accade sul server di produzione in riferimento ai siti di produzione. Quando capita, la backoffice rimane inutilizzabile. 

== Soluzione temporanea ==

La soluzione temporanea è quella di disabilitare il Just-in-time debugging. Sono state seguite le istruzioni di [http://www.hanselman.com/blog/HowToTurnOffdisableTheNETJITDebuggingDialog.aspx questo post], che riporto qua sotto:

<blockquote>
A day may come when you want to turn off the Debug dialog that appears when a .NET program has an unhandled exception.

'''Option 1: Registry key from Enabling JIT Debugging'''

For an application that includes managed code, the common language runtime will present a similar dialog to JIT-attach a debugger. The registry key that controls this option is called ''HKEY_LOCAL_MACHINE\Software\Microsoft\.NETFramework\DbgJITDebugLaunchSetting''.

* If value = 0, prompt the user by means of a message box. The choices are:
** Continue. This results in a stack dump and process termination.
** Attach a debugger. In this case, the runtime spawns the debugger listed in the DbgManagedDebugger registry key. If none, control is returned, and the process is terminated.
* If value = 1, simply return control. This results in a stack dump, after which the process is terminated.  (No more dialog)
* If value = 2, spawn the debugger listed in the DbgManagedDebugger registry key.

'''Option 2: If you want to disable the JIT debug dialog, but still want an error dialog'''

Visual Studio.NET|Tools|Options|Debugging|Just-In-Time and deselect "Common Language Runtime" and now you’ll get an OK/Cancel dialog instead of the select a Debugger Dialog.  Note: The registry entry from Option 1 above will need to be 0 for the dialog to show up.
Thanks to Eric Deslauriers of Corillian QA for these tips!

Prima dell'intervento, la chiave indicata nell'opzione 1 aveva valore esadecimale 10 (decimale 16).
