c# - 尝试在 linux 中构建 Azure 函数应用程序，以下错误返回“未找到作业函数。尝试公开您的作业类和方法”

问题描述

当我尝试在 Linux（Ubuntu 18.04）中构建 azure 函数时，会返回以下错误。以下是我在此过程中遵循的步骤。从 git 克隆存储库后。

dotnet build
func start --build

并在输出返回之后，

[5/29/19 6:46:18 AM] No job functions found. Try making your job classes and methods public. If you're using binding extensions (e.g. Azure Storage, ServiceBus, Timers, etc.) make sure you've called the registration method for the extension(s) in your startup code (e.g. builder.AddAzureStorage(), builder.AddServiceBus(), builder.AddTimers(), etc.).

解决方案

尝试这种错误的几个选项：

  • 你从哪里运行'func start --build'？确保从具有构建工件的文件夹中运行它，例如bin\Debug\net461.

  • 如果您从另一个项目或版本转换。

在 VS csproj 文件中，确保存在 AzureFunctionsVersion

<Project Sdk="Microsoft.NET.Sdk">
<PropertyGroup>
    <TargetFramework>netstandard2.0</TargetFramework>
    <AzureFunctionsVersion>v2</AzureFunctionsVersion>
</PropertyGroup>
...etc
  • 如果不是，您应该升级到最新的 Microsoft.NET.Sdk.Functions，有时示例中的代码仓库版本较低。

试试这些，看看它是否有效，如果没有，请提供代码回购链接将继续前进。
