c# - 由于缺少程序集引用，Azure 部署失败

Question

所以我有一个简单的 C# Web API 项目，我正在尝试将其部署到 Azure 中。该项目在本地构建并运行良好(不是总是这样吗？!？)，但在 Azure 中，由于缺少使用的 Microsoft.ServiceBus 程序集而失败。

项目结构非常简单:

\
--\Common
----MyProj.common.dll << This uses Microsoft.ServiceBus and has its own packages.config with WindowsAzure.ServiceBus referenced
--\Web
----MyProj.Api << This has an assembly reference to MyProj.common.dll. It doesn't have a reference to WindowsAzure.ServiceBus itself (although I added one to see if it helped, but it didn't)

Azure 部署脚本的输出如下:

我注意到它在任何时候都不会尝试恢复通用程序集的包 - 我如何“告诉”Azure 执行此操作？这还是问题吗？

查看使用 Kudu 的部署脚本，它似乎正在执行解决方案范围的恢复，因此不确定如何/为什么缺少程序集引用:

:: 1. Restore nuget packages
call :ExecuteCmd dotnet restore "MyProj\MyProj.sln"
IF !ERRORLEVEL! NEQ 0 goto error

谢谢

I notice at no point does it attempt to restore the package for the Common assembly - how do I 'tell' Azure to do this? And is this even the issue?

根据您的描述，您的项目是.net core项目。

您提到Servicebus Libriary (WindowsAzure.ServiceBus 4.0.0) 与 .NET Core 不兼容。和新的Libriary ，这是预发布版本，100% 兼容。我们可以获取更多详细信息here .

我们也可以从另一个SO thread找到它.

根据您的评论我更新答案:

我还尝试创建 C# Web API 项目并将其部署到 Azure，它在我这边工作正常。

请尝试清理构建并使用新的 WebApp 再次重建项目。

以下是我的详细步骤:

1.创建一个名为common的类库项目和一个具有GetQueue函数的公共(public)ServiceBusHelper类

2.创建一个WebApp项目并引用Common.dll和Microsoft.ServiceBus.dll，然后更改getvaules函数来获取队列

 public List<QueueDescription> Get()
        {
            var queueList = Common.ServiceBusHelper.GetQueueList();
            return queueList;
        }

3.将WebApi发布到Azure时从Auzre WebApp中删除现有文件

4.测试Web应用程序
