ASP.Net Zero Version: v10.2 ASP.Net Core + Angular

After publising in Azure App Service, we are getting following error on Application startup

`Unhandled exception. System.IO.FileNotFoundException: Could not find file 'C:\Program Files (x86)\SiteExtensions\ApplicationInsightsAgent\2.8.45\ExtensionManager\log4net.Production.config'.

Can you please let us know if log4net configuration in Startup.cs through ABP has changed or if we need to make any changes to the config file?

Here is the current log4net.Production.config

&lt;?xml version=&quot;1.0&quot; encoding=&quot;utf-8&quot; ?&gt;
&lt;log4net&gt;
  &lt;appender name=&quot;Console&quot; type=&quot;log4net.Appender.ConsoleAppender&quot;&gt;
    &lt;layout type=&quot;log4net.Layout.PatternLayout&quot;&gt;
      &lt;conversionPattern value=&quot;%-5level %date [%-5.5thread] %-40.40logger - %message%newline&quot; /&gt;
    &lt;/layout&gt;
  &lt;/appender&gt;
  &lt;appender name=&quot;RollingFileAppender&quot; type=&quot;log4net.Appender.RollingFileAppender&quot; &gt;
    &lt;file value=&quot;App_Data/Logs/Logs.txt&quot; /&gt;
    &lt;appendToFile value=&quot;true&quot; /&gt;
    &lt;rollingStyle value=&quot;Size&quot; /&gt;
    &lt;maxSizeRollBackups value=&quot;10&quot; /&gt;
    &lt;maximumFileSize value=&quot;10000KB&quot; /&gt;
    &lt;staticLogFileName value=&quot;true&quot; /&gt;
    &lt;layout type=&quot;log4net.Layout.PatternLayout&quot;&gt;
      &lt;conversionPattern value=&quot;%-5level %date [%-5.5thread] %-40.40logger - %message%newline&quot; /&gt;
    &lt;/layout&gt;
  &lt;/appender&gt;
  &lt;root&gt;
    &lt;appender-ref ref=&quot;Console&quot; /&gt;
    &lt;appender-ref ref=&quot;RollingFileAppender&quot; /&gt;
    &lt;level value=&quot;WARN&quot; /&gt;
  &lt;/root&gt;
&lt;/log4net&gt;

    Hi,

    Could you share log4net configuration in Startup.cs as shown below and try again ?

    options.IocManager.IocContainer.AddFacility<LoggingFacility>(
                    f => f.UseAbpLog4Net().WithConfig(_hostingEnvironment.IsDevelopment()
                        ? Path.Combine(_hostingEnvironment.WebRootPath,"log4net.config") 
                        : Path.Combine(_hostingEnvironment.WebRootPath,"log4net.Production.config"))
                );

    HI @ismcagdas

    We tried changing the log4net configuration as suggested above but the error still exists.

    Just FYI, this was working since very long time. This issue would occur occaisonally but would go away after publishing again.

    Please let us know if you would like us to try something else or get some logs from App Service.

    Thanks, Chaitanya

    Hi,

    Are there any differences in deployments ? Is it possible that (maybe), some of your payments are in debug mode and some other are release ?

    Hi,

    Sorry, I did not get that last comment. The Publish from VS to Azure App Service is always in Release mode.

    Thanks, Chaitanya

    Hi,

    It seems like your app is getting the URL C:\Program Files (x86)\SiteExtensions\ApplicationInsightsAgent\2.8.45\ExtensionManager sometimes but we haven't seen such a case before. For the post above https://support.aspnetzero.com/QA/Questions/11803/Application-Startup-error-due-to-log4netProductionconfig-not-found-in-Azure-App-Service#answer-c67be5f1-072d-37cb-5b01-3a0f796824e2, instead of _hostingEnvironment.WebRootPath, could you write full path of your app's deployed location and see if it works ?
