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。请尝试将作业类和方法公开”

Question

当我尝试在Linux（Ubuntu 18.04）中构建azure函数时，返回错误。以下是我在从git克隆存储库process.After中遵循的步骤。

dotnet build
func start --build

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.).

尝试这种错误的几个选项:

>

您在哪里运行“func start--build”？确保从包含构建工件的文件夹中运行它，例如bin\Debug\net461。

如果您是从另一个项目或版本转换而来。

在 VS csproj 文件中，确保 AzureFunctionsVersion 存在

<Project Sdk="Microsoft.NET.Sdk">
<PropertyGroup>
    <TargetFramework>netstandard2.0</TargetFramework>
    <AzureFunctionsVersion>v2</AzureFunctionsVersion>
</PropertyGroup>
...etc

• 您应该升级到最新的Microsoft.NET.Sdk。函数如果不是，则示例中的代码库有时具有较低版本

尝试这些，看看它是否有效，如果没有，请提供代码存储库链接将推进它。
