我的解决方案包含一个主 Web 应用，并附加了多个 Azure Web 作业。当我去发布主 Web 应用程序时，我收到此错误：
[project_path][project_name].csproj(0,0): Error MSB4057: The target "AddScheduledJob" does not exist in the project.
我不确定AddScheduledJob是从哪里来的。它不是解决方案中任何项目的名称。
我想我已经找到了"尝试"引用此幻影项目的文件：
[solution_path]packagesMicrosoft.Web.WebJobs.Publish.1.0.7toolswebjobs.console.targets
此文件包含以下文本片段：
<Target Name="AddScheduledJob"
DependsOnTargets="$(AddScheduledJobDependsOn)"
AfterTargets="MSDeployPublish"
Condition="'$(FilePreview)' == 'false' and ('$(WebJobPublishFromWAP)' == 'true' or '$(_DestinationType)' == 'AzureWebSite')">
<CreateScheduledWebJob JobConfig="@(JobConfig)"
WebSiteName="$(WebSiteName)"
WebSiteUrl="$(WebSiteUrl)"
ManagementUri="$(WebJobManagementUri)"
ManagementCertificatePath="$(ManagementCertificatePath)"
ManagementCertificatePassword="$(ManagementCertificatePassword)"
ManagementCertificate="$(ManagementCertificate)"
ManagementToken="$(ManagementToken)"
PublishSettingsPath="$(PublishSettingsPath)"
SubscriptionId="$(SubscriptionId)"
Condition="'%(RunMode)' == 'Scheduled'"/>
我不知道这是从哪里来的，或者为什么它会导致问题。我很想删除该片段，但在文件顶部，我阅读了以下片段：
WARNING: DO NOT MODIFY this file, this file is added to your project automatically...
我可以安全地从"webjobs.console.targets"文件中删除此代码段吗？或者，是否还有其他事情正在发生？
更新
我发现即使出现此错误，我的 Web 应用程序也已成功发布。以下是发布过程结束时日志的更深入视图：

如您所见，它说"发布成功"，然后抱怨其中一个作业的"开始时间"。然后抱怨"添加计划作业"。我不关心"开始时间"问题。我可以解决这个问题。但是关于名为"AddScheduledJob"的项目的错误令人困惑。即使发布似乎发生了，我也不希望此错误弄乱日志。导致此错误的原因是什么？
这是一个古老的NuGet包。在旧版本中，如果将 Web 作业配置为按计划运行而不是连续运行，Visual Studio 将允许您配置 Web 作业的计划。您可以删除该目标并使用以下指南配置计划：https://learn.microsoft.com/en-us/azure/app-service/web-sites-create-web-jobs#CreateScheduledCRON 。如果您使用的是旧版本的 Visual Studio，请升级，以便拥有最新的 Web Job 项目模板。
首先，必须从 Nuget 添加Microsoft.Web.WebJobs.Publish包。即使 VS 具有"发布到 Web 作业"操作，也不会自动将该包添加到项目中。 你可以参考这个博客。
一旦你添加它，你仍然被搞砸了。VS 不会自动修改您的.csproj文件以使用此包。 为此，您需要手动破解.csproj文件。最简单的方法是在 VS 中卸载它，并在 CSharp 目标之后添加以下行 - 我在下面包含了它作为上下文：
<Import Project="$(MSBuildToolsPath)Microsoft.CSharp.targets" />
<Import Project="..packagesMicrosoft.Web.WebJobs.Publish.1.0.11toolswebjobs.targets"
Condition="Exists('..packagesMicrosoft.Web.WebJobs.Publish.1.0.11toolswebjobs.targets')" />
这是您的类似问题。当他在 asp.net 站点下添加新的 Web 作业时，请保留较新版本的Microsoft.Web.WebJobs.Publish包。
