问题描述

我将 NLog 添加到我的应用程序和它的测试项目中.它们都是同一解决方案的一部分.从应用程序内部 NLog 工作.但是从测试项目中得到以下异常:

I added NLog to my application and the test project for it. Both of them part of the same solution. From inside the application NLog works. But from test project get below exception:

Unable to create instance of type Common.Logging.NLog.NLogLoggerFactoryAdapter. Possible explanation is lack of zero arg and single arg Common.Logging.Configuration.NameValueCollection constructors

我的 NLog 配置如下:

My NLog configuration is below:

推荐答案

当我仔细查看时，发现一个内部异常，抱怨找不到 nlog 2.0.0 dll.找到如下解决方案

When I took a closer look there was an inner exception which complained an nlog 2.0.0 dll was not found. Found a solution as follows

1. 删除所有与 nlog 和 commons logging 重启应用程序相关的包.如果包没有被 nuget 删除，请手动编辑 .csproj 文件和 .packages 文件以删除对 Commons 日志记录或 nlog 包的所有引用.
2. 然后通过在搜索文本框中输入 Common.Logging.Nlog 来搜索最新的 nlog 包.然后选择最新的 nlog 包，它将安装所有其他需要的包，以便通过公共日志记录作为依赖项使用 nlog.如下所示:

3. 在您的 web.config 中更新您的工厂适配器元素在我的情况下，我选择了 31，因此将其更新为

1. Delete all packages related to nlog and commons logging restart application. If the packages don't get deleted by nuget edit .csproj file and .packages file manually to remove all references to Commons logging or nlog packages.
2. Then searched for latest nlog package as by entering Common.Logging.Nlog in search text box. Then pick the latest nlog package and it will install all other needed packages for using using nlog through commons logging as a dependency. As shown below:

3. In your web.config update your factory adapter element In my case i selected 31 so updated it to
