XAF Logging with log4net

created 8 years ago

Hi I have implemented my own trace listener  with log4net as suggested in
https://www.devexpress.com/Support/Center/Question/Details/Q234241/tracing-write-log-messages-to-database

and it works fine.
However the devexpress log file "eXpressAppFramework.log" is still created.

If I configure the switch
<add name="eXpressAppFramework" value="0"/>
to zero the file is not created, but there are also no traces logged to the trace listener obviously.

So how can one use a custom trace listener and prevent the defult log file from creating?

Hi Patrick,

Call the Tracing.Initialize method with an empty string parameter to suppress the default TraceListener creation. This should be done before an XafApplication instance is created, because otherwise, the default listener will be initialized, and the XAF log file will be created. Here is an example:

C#
public static void Main(string[] arguments) {  
    ...  
    Trace.Listeners.Add(new TextWriterTraceListener("test.log"));  
    Tracing.Initialize(String.Empty);  
    MainDemoWinApplication winApplication = new MainDemoWinApplication();
