MAUI Exception Line Numbers / Debug Symbols

Question

When I log an exception in my MAUI App (Android), the stacktrace doesn't contain line numbers (only if the debugger is attached!). I need stacktrace line numbers in release builds without attached debugger.
Is this still not possible? / do I still have to use use mono-symbolicate to convert stacktraces? https://github.com/xamarin/release-notes-archive/blob/master/release-notes/android/xamarin.android_7/xamarin.android_7.4/index.md#file-name-and-line-number-information-in-release-builds)

MainPage.xaml.cs (new MAUI App from default template)

        private void OnCounterClicked(object sender, EventArgs e)  
        {  
            try  
            {  
                throw new Exception("test");  
            }  
            catch (Exception ex)  
            {  
                Console.WriteLine("Exception: {0}", ex);  
            }  
        }  

Output with debugger
01-09 20:12:28.740 31662 31662 I DOTNET : Exception: System.Exception: test
01-09 20:12:28.740 31662 31662 I DOTNET : at ExceptionLineNumberTest.Maui.MainPage.OnCounterClicked(Object sender, EventArgs e) in /Users/xxxx/Projects/ExceptionLineNumberTest.Maui/ExceptionLineNumberTest.Maui/MainPage.xaml.cs:line 27

Output without debugger
01-09 20:13:07.055 32175 32175 I DOTNET : Exception: System.Exception: test
01-09 20:13:07.055 32175 32175 I DOTNET : at ExceptionLineNumberTest.Maui.MainPage.OnCounterClicked(Object sender, EventArgs e)

Answer 1

Yes, you need to symbolicate your log file to get the exception line numbers.

In addition, you could try to use this .Net CLI dotnet-stack to do it on .Net 6 and 7 applications.

Please refer to Inspect managed stack traces to get more details.
