我在Visual Studio 2012中通过“管理NuGet包”选项安装了Hangfire.我将SQL Server 2008 R2用于一个项目,将SQL Server 2012 Enterprise用于另一个项目.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).
我根据Owin& amp;的要求添加了一个新的启动文件. Hangfire配置.该文件如下：
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安装会自动在web.config中添加以下行：
<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行收到以下错误：

请注意,安装没有创建HangFireConfig.cs文件.
感谢阅读和任何帮助将非常感谢.
解决方法:
我和你几乎有过相同的经历.鉴于我正在使用.Net 4和MVC 3.
为了卸载Hangfire_net40,我不得不在包目录中手动删除Microsoft.Bcl.Build.1.0.14.之后,我安装了common.logging.core 2.2.0版
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this
<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
在此之后,网络应用程序启动正常.
我想问题是Hangfire_net40 NuGet包选择了错误的日志核心包.
