The ':' character, hexadecimal value 0x0x3A, cannot be included in a name. at System.Xml.XmlWellFormedWriter.CheckNCName(String ncname) at System.Xml.XmlWellFormedWriter.WriteStartElement(String prefix, String localName, String ns) at log4net.Layout.XmlLayoutSchemaLog4j.FormatXml(XmlWriter writer, LoggingEvent loggingEvent) at log4net.Layout.XmlLayoutBase.Format(TextWriter writer, LoggingEvent loggingEvent) at log4net.Appender.FileAppender.Append(LoggingEvent loggingEvent) at log4net.Appender.AppenderSkeleton.DoAppend(LoggingEvent loggingEvent) ```
