將Angle CLI更新到ASP.NET Core 2.2中的最新版本

Question

我用角度創建了asp.net core 2.2項目，並將角度cli更新為8。

The NPM script 'start' exited without indicating that the Angular CLI was listening for requests. The error output was: The serve command requires to be run in an Angular project, but a project definition could not be found

我從angular.json文件中刪除了--extract，但仍然拋出錯誤，

誰能指導如何安全地將asp.net核心angular cli版本升級到最新版本

我當前的angular.json文件是

"dependencies": {
    "@angular/animations": "^5.2.0",
    "@angular/common": "^5.2.0",
    "@angular/compiler": "^5.2.0",
