我从角度开始（对Asp.Net核心有点经验） . 我想使用.Net核心，因为我喜欢MS正在采取的方向（而且我非常流利于.Net :)） .

我做了什么：

这在控制台中出现了很多错误：

这在网页上：

错误 . 处理您的请求时发生错误 . 请求ID：0HLF1EQKVCJ2V：00000001开发模式交换到开发环境将显示有关发生的错误的更多详细信息 . 不应在已部署的应用程序中启用开发环境，因为它可能导致向最终用户显示异常的敏感信息 . 对于本地调试，可以通过将ASPNETCORE_ENVIRONMENT环境变量设置为Development并重新启动应用程序来启用开发环境 .

我错过了什么？或者你建议我用Asp.Net核心和角度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 .

Edit 我尝试使用开发环境（使用 SET ASPNETCORE_ENVIRONMENT=Development ），但在运行应用程序时它会直接崩溃（我不必在网页上）：
