[英]Load assembly in async Task asp.net
我运行异步任务,该任务使用引用的DLL中的代码。 在这种情况下,我会显示一条错误消息,指出找不到此引用的DLL。
Message: Unable to find assembly 'Newtonsoft.Json, Version=8.0.0.0, Culture=neutral, PublicKeyToken=30ad4fe6b2a6aeed'.

如果代码在异步任务中,则DLL是从其他位置获取的? 我应该将其安装到GAC吗?
这是我的web.config:
<runtime>
<assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
<dependentAssembly>
<assemblyIdentity name="Newtonsoft.Json" publicKeyToken="30ad4fe6b2a6aeed" culture="neutral" />
<bindingRedirect oldVersion="0.0.0.0-8.0.0.0" newVersion="8.0.0.0" />
</dependentAssembly>
在Bin文件夹中,我有一个Newtonsoft.Json.Dll,我运行powershell脚本检查版本是什么:
[Reflection.AssemblyName]::GetAssemblyName('MyLocation\Newtonsoft.Json.DLL').Version
结果是:
Major Minor Build Revision
----- ----- ----- --------
8 0 0 0
然后,我想检查使用listDlls.exe将哪些程序集加载到w3wp.exe进程中,并且有:
C:\Windows\Microsoft.NET\Framework64\v4.0.30319\Temporary ASP.NET Files\root\xxx\Newtonsoft.Json.DLL
所以我导航到那里复制了dll并检查了版本(只是为了确定),它是8.0.0.0
我不确定我还能做什么:D
我看到这是来自CrossAppDomainSerializer的跨域序列化异常,用作远程基础结构接收器,用于跨上下文边界进行调用
这是源于您的代码的问题,远程处理已完成,请参阅此SO 帖子 。
希望这可以帮助!
