Log4net go from MVC to Netcore

The original project with the Log4net, but the version is older, in the core of the new version is also supported, this article is now the latest release 2.0.8

1. Loghelper Help class put another class library in Log/loghelper.cs

2, the separate configuration file is placed under the main project, Logconfig/log4net.config

Specific locations such as:

LogHelper.cs Content
Upgrade version after the original Logmanager.getlogger () method to specify repository see the article is to createrepository one.
private static readonly Iloggerrepository Repository = Logmanager.createrepository (assembly.getentryassembly (), typeof (Hierarchy))

However, I do not write this way, no error log will not be written. Back study half-day with getrepository solution.
private static readonly Iloggerrepository Repository = Logmanager.getrepository (assembly.getcallingassembly ());

This is because different messages are placed in different file classification processing "Ogger name=" Logerror "this property.

PS: In the LogHelper.cs file, use [Assembly:xmlconfigurator (configfile = @ "Logconfig\log4net.config", Watch = True)] to read the configuration file, You can also register the file path in Startup.cs. However, this method is not useful for porting to other projects for independence.
