c# - 为什么项目找不到 Microsoft.Azure.WebJobs 3.0.0.0

Question

我在 Visual Studio 15.8.6 中有一个 Azure Functions (v2) 项目，其中安装了 Azure Functions 和 Web 作业工具 5.2.60618.0。我正在使用 ServiceBusTrigger。当我尝试编译该项目时，我不断收到:

Severity Code Description Project File Line Suppression State Error System.IO.FileNotFoundException: Could not load file or assembly 'Microsoft.Azure.WebJobs, Version=3.0.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies.

WRN: Assembly binding logging is turned OFF. To enable assembly bind failure logging, set the registry value [HKLM\Software\Microsoft\Fusion!EnableLog] (DWORD) to 1. Note: There is some performance penalty associated with assembly bind failure logging. To turn this feature off, remove the registry value [HKLM\Software\Microsoft\Fusion!EnableLog].

Error generating functions metadata InSysFunctionDeviceMinuteDataProcessorV2 C:\Users\Dr Kurt Richardson.nuget\packages\microsoft.net.sdk.functions\1.0.22\build\netstandard1.0\Microsoft.NET.Sdk.Functions.Build.targets 39

虽然它提示 Microsoft.Azure.WebJobs 3.0.0.0 丢失，但它在已安装的软件包中清楚地列出了:

我注意到的一件事是，尽管该项目使用 .NET Standard v2.0.3，但错误消息引用了包含 netstandard1.0 的路径 (...nuget\packages\microsoft.net.sdk.functions\1.0.22\build\netstandard1.0\Microsoft.NET.Sdk.Functions.Build.targets 3) . Nuget 表示 Microsoft.NET.Sdk.Functions v1.0.22 的目标是 .NETStandard，Version=v2.0。此外，Microsoft.Azure.WebJobs 位于 netstandard2.0 文件夹中。这可能是问题所在吗？还是别的什么？

Answer 1

参见package references in v2 .

Microsoft.Azure.WebJobs.ServiceBus 已重命名为 Microsoft.Azure.WebJobs.Extensions.ServiceBus 和 Microsoft. Azure.WebJobs 包含在 Microsoft.NET.Sdk.Functions 中，无需单独安装。

请将 Azure Functions 和 Web 作业工具更新为 latest version (现在是 15.10.2009.0)。

使用最新的扩展和模板，当我们创建服务总线触发器时，现在默认的 nuget 依赖项是

Microsoft.Azure.WebJobs.Extensions.ServiceBus v3.0.0
Microsoft.NET.Sdk.Functions v1.0.22
