【问题描述】:
我已经通过 Visual Studio 2012 中的“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,因此我无法下载与 .Net4.5 兼容的最新 Hangfire,因此我通过 NuGet 下载了 Hangfire (.Net 4.0)。
我根据 Owin 和 Hangfire 配置的要求添加了一个新的启动文件。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>
当我运行项目时,我在 第 29 行 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 27: app.UseHangfire(config =>
Line 28: {
Line 29: config.UseSqlServerStorage("ASP_NETConnectionString");
Line 30: config.UseServer();
Line 31: });
当我在 web.config 中评论 Common.Logging.Core 的依赖程序集时,我在 第 30 行收到以下错误:
Could not load file or assembly 'Common.Logging.Core, Version=2.2.0.0, Culture=neutral, PublicKeyToken=af08829b84f0328e' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

Source Error:
Line 28: {
Line 29: config.UseSqlServerStorage("ASP_NETConnectionString");
Line 30: config.UseServer();
Line 31: });
Line 32: }
Common.Logging.Core dll 的不同版本似乎存在配置问题(不兼容),请注意我的 bin 文件夹中只有一个文件 Common.Logging.Core (V3.0.0.0),我试图找到 V2.2.0.0 来检查这是否能解决“无法加载 Common.Logging.LogManager”但我在网络上找不到这个 dll,请指教。
请注意,安装没有创建 HangFireConfig.cs 文件。
感谢您的阅读,我们将不胜感激。

我也在 Hangfire 网站上提出了这个问题。 discuss.hangfire.io/t/…
