My C# application is returning 0xE0434352 to Windows Task Scheduler but it is not crashing
C#.NetScheduled TasksTaskC# Problem Overview
I have written a few C# apps that I have running via windows task scheduler. They are running successfully (as I can see from the log files that they are writing ) but windows task scheduler shows them returning a last run result of 0xE0434352. Is there something I need to do in my C# application so that it returns a success code to the windows task scheduler?

Another option is to simply use the Application log accessible via the Windows Event Viewer. The .Net error will be recorded to the Application log.
You can see these events here:
Event Viewer (Local) > Windows Logs > Application

When setup a job in new windows you have two fields "program/script" and "Start in(Optional)". Put program name in first and program location in second. If you will not do that and your program start not in directory with exe, it will not find files that are located in it.

Hans Passant was correct, I added a handler for AppDomain.CurrentDomain.UnhandledException as described here http://msdn.microsoft.com/en-us/library/system.appdomain.unhandledexception(v=vs.71).aspx I was able to find the exception that was occurring and corrected it.

I was referencing a mapped drive and I found that the mapped drives are not always available to the user account that is running the scheduled task so I used \\IPADDRESS instead of MAPDRIVELETTER: and I am up and running.

In case it helps others, I got this error when the service the task was running at didn't have write permission to the executable location. It was attempting to write a log file there.

I had this issue and it was due to the .Net framework version. I had upgraded the build to framework 4.0 but this seemed to affect some comms dlls the application was using. I rolled back to framework 3.5 and it worked fine.
Solution 7 - C#
I got the same error but I have fixed it by changing the file reading path from "ConfigFile.xml" to AppDomain.CurrentDomain.BaseDirectory.ToString() + "ConfigFile.xml"
In my case, this error due to file path error because task manager starts program from "System32" as initial path but the folder we thought.

I was getting the same message message within dotNet Core 2.2 using MVC 5, however nothing was being logged to the Windows Event Viewer.
I found that I had changed the Project sdk from Microsoft.NET.Sdk.Web to Microsoft.NET.Sdk.Razor (seen within the projects.csproj file). I changed this back and it worked fine :)

In my case it was because I had message boxes. Once I commented that code out, it started working. I remembered that could be a problem when I looked at the event log as suggested in this thread. Thank you everyone!

I encountered this problem when working with COM objects. Under certain circumstances (my fault), I destroyed an external .EXE process, in a parallel thread, a variable tried to access the com interface app.method and a COM-level crash occurred. Task Scheduler noticed this and shut down the app. But if you run the app in the console and don't handle the exception, the app will continue to work ...
Please note that if you use unmanaged code or external objects (AD, Socket, COM ...), you need to monitor them!

Also message box in PowerShell. I converted PowerShell script to exe. When running as admin it's worked but in task schedule I received this error also. There was an line in PowerShell script with write-output. After commented this line and compile new exe Task Schedule was completed successfully.

It is permission issue in my case the task scheduler has a user which doesn't have permission on the server in which the database is present.
