Hangfire配置问题(Common.Logging.Core & Common.Logging.LogManager)

Question

我已经在Visual 2012中通过“管理NuGet包”选项安装了Hangfire。一个项目使用Server 2008 R2，另一个项目使用SQLServer2012Enterprise。我的项目与.Net 4.0兼容，所以我无法下载与.Net4.5兼容的最新Hangfire，所以我通过NuGet下载了Hangfire (.Net 4.0)。

我按照Owin & Hangfire配置的要求添加了一个新的启动文件。档案如下：

​

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using Hangfire;
using Hangfire.SqlServer;
using Microsoft.Owin;
using Owin;

/// <summary>
/// Summary description for Startup
/// </summary>
/// 
[assembly: OwinStartup(typeof(MyProj.Startup))]
namespace MyProj
{
    public class Startup
    {
        public Startup()
        {
            //
            // TODO: Add constructor logic here
            //
        }
        public void Configuration(IAppBuilder app)
        {
            app.UseHangfire(config =>
            {
                config.UseSqlServerStorage("ASP_NETConnectionString");
                config.UseServer();
            });
        }
    }
}

​

Hangfire安装在web.config中自动添加了以下行：

​

  <runtime>
    <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
      <dependentAssembly>
        <assemblyIdentity name="Common.Logging.Core" publicKeyToken="af08829b84f0328e" culture="neutral" />
        <bindingRedirect oldVersion="0.0.0.0-3.0.0.0" newVersion="3.0.0.0" />
      </dependentAssembly>
      <dependentAssembly>
        <assemblyIdentity name="System.Runtime" publicKeyToken="b03f5f7f11d50a3a" culture="neutral" />
        <bindingRedirect oldVersion="0.0.0.0-2.6.8.0" newVersion="2.6.8.0" />
      </dependentAssembly>
      <dependentAssembly>
        <assemblyIdentity name="System.Threading.Tasks" publicKeyToken="b03f5f7f11d50a3a" culture="neutral" />
        <bindingRedirect oldVersion="0.0.0.0-2.6.8.0" newVersion="2.6.8.0" />
      </dependentAssembly>
    </assemblyBinding>
  </runtime>

​

当我运行该项目时，我在第29行上收到以下错误：

​

Could not load type 'Common.Logging.LogManager' from assembly 'Common.Logging.Core, Version=3.0.0.0, Culture=neutral, PublicKeyToken=af08829b84f0328e'.

Line 30:                 config.UseServer();
Line 31:             });

​

当我在Common.Logging.Core中注释web.config的依赖程序集时，在第30行上收到以下错误

​

Line 31:             });
Line 32:         }

​

不同版本的Common.Logging.Core dll似乎存在配置问题(不兼容)，请注意，我在Common.Logging.Core的bin文件夹中只有一个文件(V3.0.0.0)，我试图查找V2.2.0.0来检查这是否会解决“无法加载Common.Logging.LogManager”的问题，但我在网上找不到这个dll，请注意。

请注意，安装没有创建HangFireConfig.cs文件。

感谢您的阅读和任何帮助，将不胜感激。

我和你的经历几乎一样。考虑到我使用的是.Net 4和MVC 3。

为了卸载Hangfire_net40，我不得不手动删除包目录中的Microsoft.Bcl.Build.1.0.14。之后，我安装了common.logging.core版本2.2.0

Install-Package Common.Logging.Core -Version 2.2.0 

然后重新安装hangfire_net40

Install-Package Hangfire_net40

在web.config文件中，我将common.logging核心的程序集绑定行更改为

<bindingRedirect oldVersion="0.0.0.0-2.2.0.0" newVersion="2.2.0.0" />

并确保我的项目中的引用指向2.2.0，而不是3.3.0之后，web应用程序启动良好。我猜问题在于Hangfire_net40 NuGet包选择了错误的日志核心包。
