Question

我从有角度的开始（对Asp.Net核心有一点点的经验）。我想使用.Net内核，因为我喜欢MS的发展方向（而且我对.Net相当熟练）。

我做了什么：

将VS 2017和VS Code升级到最新版本
更新了npm（npm update npm -g）
dotnet new angular
更新了所有内容（带有https://www.npmjs.com/package/npm-update-all）。也做了npm audit fix
运行该应用程序（dotnet run）
转到http://localhost:5000

这在控制台中产生了很多错误：

这在网页上：

错误。处理您的请求时发生错误。要求编号：   0HLF1EQKVCJ2V：00000001

将开发模式切换到开发环境将显示更多   有关发生的错误的详细信息。

不应在已部署的环境中启用开发环境   应用程序，因为它可能会导致来自   向最终用户显示异常。对于本地调试，   可以通过设置开发环境来启用   ASPNETCORE_ENVIRONMENT环境变量为Development，并且   重新启动应用程序。

我想念什么？或者您会建议我以Asp.Net核心和有角的6开始一个项目（我喜欢HMR的想法，我希望一切都由asp.net核心（静态资源和服务）托管。

修改我尝试使用开发环境（与SET ASPNETCORE_ENVIRONMENT=Development一起使用，但是随后在运行应用程序时它直接崩溃（我不必进入网页）：

如何在angular 6中使用ASP .Net核心？
