only takes a minute: Sign up AppDomain, handling the exceptions up vote 13 down vote favorite 7 I am developing a large application which consists of many smaller plugins/applications. They are not big enough to be a full process, https://msdn.microsoft.com/en-us/library/system.appdomain.firstchanceexception(v=vs.110).aspx but are too small to be run in a thread, under one process, along with that I want to have it based on a plugin-basis. If a newer version of that plugin is available it should be unloaded, updated and started again. During my search for a solution I can accross the magic word AppDomain, and I quote: "Use application domains to isolate tasks that might bring down a process. If the state of the AppDomain that's executing a task http://stackoverflow.com/questions/7071957/appdomain-handling-the-exceptions becomes unstable, the AppDomain can be unloaded without affecting the process. This is important when a process must run for long periods without restarting. You can also use application domains to isolate tasks that should not share data." Thus that is exactly what I want. However, I guess their 'State becomes unstable' is a different point of view than mine. I am thinking of a problem where one of the plugins throws an exception, for whatever reason. I would like that be catched, e-mailed, unloaded and restart (if possible). So I created an application that starts up, looks for all .dll's in its folder. Checks if the dll consists of a plugin. Creates a new AppDomain for that plugin, and once everything is loaded it will start each plugin. (Where each plugin can consist of multiple threads, co-existing happily next to ech other). So I also added a time-out in there, that fires after 5seconds to throw a new Exception(); Added a UnhandledException event on the AppDomain to handle it. But, it catched it, and after cathing, still 'crashed' the whole process including all the extra child-AppDomains. But it clearly states in the quote 'to isolate tasks that "might" bring down a process'. So am I missing something vital? Is my view on the quote wrong? c# .net share|improve this question edited Aug 16 '11 at 1:58 John Saunders 138k20175319 asked Aug 15 '11 at 23:25 Daan Ti

Join them; it only takes a minute: Sign up Handling unhandled exceptions problem unhandled exception up vote 22 down vote favorite 9 I wanted to set some handler for all the unexpected exceptions that I might not have caught inside my code. In Program.Main() I used the following code: AppDomain.CurrentDomain.UnhandledException += new UnhandledExceptionEventHandler(ErrorHandler.HandleException); But it didn't work as I expected. When I started the application in debugging mode and threw an exception it did call the handler, but afterwards the exception appdomain error handler helper in Visual Studio popped up as if the exception occurred without any handling. I tried Application.Exit() inside the handler but it didn't work as well. What I would like to achieve is that the exception is handled with my handler and then the application closes nicely. Is there any other way to do it or am I using the code above in the wrong way? c# exception share|improve this question edited Jan 2 '09 at 9:56 David Schmitt 36.6k1588146 asked Jan 2 '09 at 9:42 agnieszka 5,1152273107 add a comment| 5 Answers 5 active oldest votes up vote 17 down vote accepted It's because you're running it through Visual Studio in Debug mode. If you release and install your app somewhere else, nothing but your global exception handler will be processed. share|improve this answer answered Jan 2 '09 at 9:45 Peter Lindholm 89641325 add a comment| up vote 25 down vote Normally I use something like this to try and catch all unexpected top-level exceptions. using System; static class Program { [STAThread] static void Main(string[] argv) { try { AppDomain.CurrentDomain.UnhandledException += (sender,e) => FatalExceptionObject(e.ExceptionObject); Application.ThreadException += (sender,e) => FatalExceptionHandler.Handle(e.Exception); // whatever you ne

Join them; it only takes a minute: Sign up Should use both AppDomain.UnhandledException and Application.DispatcherUnhandledException? up vote 19 down vote favorite 8 After reading some excellent posts about the difference between AppDomain.UnhandledException and Application.DispatcherUnhandledException, it appears that I should be handling both. This is because it is significantly more likely the user can recover from an exception thrown by the main UI thread (i.e., Application.DispatcherUnhandledException). Correct? Also, should I also give the user a chance to continue the program for both, or just the Application.DispatcherUnhandledException? Example code below handles both AppDomain.UnhandledException and Application.DispatcherUnhandledException, and both give the user the option to try to continue despite the exception.
