Question

我一直在使用log4net，所以我不是很新的。但这是我在Windows Server 2008 R2 64位计算机上部署的第一个更大的.NET 4.0解决方案。

当然我先搜索并找到类似的主题。一个主题听起来完全相同 - log4net doesn't log when running a .Net 4.0 Windows application built in Release mode - 但我的问题仍然不同。

我的部分解决方案是使用log4net的控制台应用程序。一切正常，直到我切换到发布版本。在我的电脑上测试期间它仍然正常。但是在服务器端，log4net将不再起作用。

所以我启用了log4net内部调试。这指向存储库冲突。我从来没有深入到log4net深入了解它。但问题似乎是它首先为域程序集（CRMFacade.Domain）创建一个存储库，然后尝试为控制台应用程序（CRMFacade.DataImport）创建一个存储库。此操作失败，因为已存在默认存储库：

log4net: log4net assembly [log4net, Version=1.2.10.0, Culture=neutral, PublicKeyToken=1b44e1d426115821]. Loaded from [Global Assembly Cache]. (.NET Runtime [4.0.30319.225] on Microsoft Windows NT 6.1.7601 Service Pack 1)
log4net: DefaultRepositorySelector: defaultRepositoryType [log4net.Repository.Hierarchy.Hierarchy]
log4net: DefaultRepositorySelector: Creating repository for assembly [CRMFacade.Domain, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null]
log4net: DefaultRepositorySelector: Assembly [CRMFacade.Domain, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null] Loaded From [C:\Program Files (x86)\CRMFacade.DataImport\CRMFacade.Domain.dll]
log4net: DefaultRepositorySelector: Assembly [CRMFacade.Domain, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null] does not have a RepositoryAttribute specified.
log4net: DefaultRepositorySelector: Assembly [CRMFacade.Domain, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null] using repository [log4net-default-repository] and repository type [log4net.Repository.Hierarchy.Hierarchy]
log4net: DefaultRepositorySelector: Creating repository [log4net-default-repository] using type [log4net.Repository.Hierarchy.Hierarchy]
log4net: DefaultRepositorySelector: Creating repository for assembly [CRMFacade.DataImport, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null]
log4net: DefaultRepositorySelector: Assembly [CRMFacade.DataImport, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null] Loaded From [C:\Program Files (x86)\CRMFacade.DataImport\CRMFacade.DataImport.exe]
log4net: DefaultRepositorySelector: Assembly [CRMFacade.DataImport, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null] does not have a RepositoryAttribute specified.
log4net: DefaultRepositorySelector: Assembly [CRMFacade.DataImport, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null] using repository [log4net-default-repository] and repository type [log4net.Repository.Hierarchy.Hierarchy]
log4net: DefaultRepositorySelector: repository [log4net-default-repository] already exists, using repository type [log4net.Repository.Hierarchy.Hierarchy]

有趣的是：在Debug构建中，控制台应用程序（CRMFacade.DataImport）是log4net为其创建存储库的第一个也是唯一的程序集。在任何一种情况下，CRMFacade.Domain都处于发布版本中。 CRMFacade.Domain还引用GAC中的log4net以发出日志输出。但它没有log4net配置。这始终由使用域程序集的程序集提供。

很奇怪，因为它仍适用于我本地计算机上的Release版本。

为了完整起见，这里是log4net调试输出，其中一切正常：

Answer 1

我们遇到了同样的问题。它仍然不清楚根本原因是什么，但我们让log4net再次运行。我们仅在使用网站程序集上的XmlConfiguratorAttribute配置log4net的网站中遇到了问题。我们设法通过直接从Application_Start（）调用XmlConfigurator.Configure()来解决这个问题。不是一个漂亮的解决方案，但似乎有效。

Answer 2

如果您下载最新的log4net代码，请在Visual Studio 2010中查看log4net项目的构建选项卡。

在调试模式下，编译器符号为NET;NET_2_0;NET_4_0。

发布模式NET_4_0 缺少。

在构建发行版之前，将发布模式中的符号更改为NET;NET_2_0;NET_4_0，您应该没有问题。在Windows资源管理器中查看已完成的DLL的文件属性。在“详细信息”下，您将看到文件描述为“用于.NET Framework 4.0的Apache log4net ”

Log4net在Debug中工作但在Release版本中失败
