对npm生成的DotNet Core 2.0 WebDeploy调用在发布上不起作用

我过去使用过一种策略，即我们的后端开发人员在VisualStudio中工作，我们的UI人员在Sublime/VSCode中工作。在VS2017网站发布期间，我使用发布目标先运行npm安装，然后运行npm构建（捆绑我们的app.js逻辑），然后将前端内容包含到WebDeploy的后端包中

我试图在dotnet core 2.0项目中复制这一点，但从未调用用于构建前端的发布目标调用（即，您从未看到echo命令内容，也没有运行npm安装/构建）。。。因此，发布时不包括UI资源，除非我以前手动运行构建过程从VSCode生成UI资源，并且它们已经存在于磁盘上。也就是说，复制UI生成的文件非常有效（如果存在的话）。。。但是VS2017从未调用npm命令来构建资源

虽然这是一个微妙的变化，但它在几个.NET4.6+项目中非常有效。我刚刚将完全相同的逻辑复制到一个核心2.0项目中，出于某种原因，它没有按照我预期的方式工作？有什么想法吗

例如，my ProjectDeploy.pubxml文件包含（在最终结束“Project”标记之前的底部）：

..\..\src应用程序
wwwroot\%（递归目录）%（文件名）%（扩展名）
自定义文件；
自定义文件；

好的，所以我不知道这是否是新的dotnetcore 2.0所特有的，但我遵循了这些链接，使事情完美地运行起来。从内置的VS2017 SPA模板开始，我现在不再采用.NET 4.6中使用的方法来修改.pubxml发布配置文件以尝试生成/复制文件。。相反，gulp/webpack构建SPA和复制构建逻辑上的文件包含在.csproj文件中。请注意，这样做的好处是您可以快速构建解决方案，而无需每次构建UI，但仍然可以在部署时捆绑所有新的UI更改。我的工作示例如下：

..\..\src应用程序

web项目（而不是发布文件）中的预构建事件会有帮助吗？我有意避免在构建过程中编译UI资源，因为这会大大降低后端开发周期。。我希望UI资源只在发布期间生成和绑定。
