警告：仅从程序集中获取部分类型：Microsoft.Azure.WebJobs.Extensions.Storage

Question

我有一个简单的 .NET V3 WebJob，在 .NET 网站中启动并运行了一个计时器触发器，如本答案所述：Scheduled .NET WebJob V3 example

但是，在输出中，我收到此警告：

warn: Host.Startup[0] Warning: Only got partial types from assembly: Microsoft.Azure.WebJobs.Extensions.Storage, Version=3.0.6.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35 The following loader failures occured when trying to load the assembly: - Could not load file or assembly 'System.ComponentModel.Annotations, Version=4.2.1.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies.

这是 GitHub ( https://github.com/Azure/azure-webjobs-sdk/issues/2060 )上的一个未决问题。有没有人有解决办法？

更重要的是，它是否以任何方式影响功能？GitHub 问题 OP 说不，但最好有人确认这一点。

Answer 1

安装包“Microsoft.Azure.WebJobs.Host.Storage”版本=“4.1.0”以修复此错误。

另外，为了避免任何混淆，在我修复此问题之前，由于软件包更新，原始问题中的错误消息已变为以下内容：

warn: Host.Startup[0]
  Warning: Only got partial types from assembly: Microsoft.Azure.WebJobs.Host.Storage, Version=4.0.1.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35
  The following loader failures occured when trying to load the assembly:

  This can occur if the assemblies listed above are missing, outdated or mismatched.
