Crashes when logs an Error with exception

[imasm]

Hi

With RichTextBoxTarget the applicatin crashes when I try to log an Error with exception argument.

if (Logger.IsErrorEnabled)
                Logger.Error("This is a message", new Exception("simple exception"));

System.MissingMethodException

'Method not found: 'Void NLog.ILogger.Error(System.Exception, System.String)'.'

This is my nlog.config

<?xml version="1.0" encoding="utf-8" ?>
<nlog xmlns="http://www.nlog-project.org/schemas/NLog.xsd"
      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">

  
  <targets>
      <target name="richTextBox" xsi:type="RichTextBox"
            layout="${time} : ${message}"
            formName="MainForm"
            ControlName="LogViewer"
            autoScroll="true"
            maxLines="20"
            useDefaultRowColoringRules="true"
            allowAccessoryFormCreation="false" />
  </targets>

  <rules>
    <logger name="*" minlevel="Info"  writeTo="richTextBox" />
  </rules>
</nlog>

Could you double check the NLog version where it's deployed? (properties of nlog.dll). It looks like there is an older version there

Yes!!

I had NLog 4.0.0, after update to 4.4.9 the code runs well.

Thank you very much for your time. I apologize for the inconvenience.
