</ItemGroup>
Log4net here again next debug log can be written to the specified directory, if released, added to the service, the logs are written to the log system32 directory, where the need to change the configuration and under the code:
<param name="File" type="log4net.Util.PatternString" value="%property{LogsDirectory}\Log\" />
log4net.GlobalContext.Properties [ "LogsDirectory"] = AppDomain.CurrentDomain.BaseDirectory; // specified directory service log
Services to write the log after this release will write to the specified destination folder in the next. . . Engage in two days to thoroughly understand, forgive me is white, I hope you see will be helpful.
