升级到 Angular 12 & Webpack

Question

I have upgraded an Angular 6 project to Angular 12 with .NET framework. I'm facing 2 issues at the moment.

1)

I have specified builds commands in package.json as:

"prodbuild": "ng build --configuration production --aot=true --output-hashing none",
"build": "ng build --output-hashing none",

and I'm able to compile using ng build --output-hashing none. However, I'm not being able to debug the code using Chorme dev tools, the source displays from Webpack and not the directory structure of project. The code I'm changing in ts files is not updating in dev tools. I have tried to clear cache, page refresh, but it is not helping.

2. I've been using earlier

   ng build --watch

what has replaced this? This was very convenient to update code and refresh in browser.

Here is my angular.json:

Please advise!

ng build compiles with production configuration by default now.

Try ng build --watch --configuration development or ng serve
