Issue 2:
When you deploy angular6 compiled files to .net server.for eg:-Client project:Angular6project
DOTNet project:TestWebAPI.
It throws following error:
/styles.3ff695c00d717f2d2a11.css:1 Failed to load resource: the server responded with a status of 404 (Not Found)
/runtime.932554c7e1000ee910b0.js:1 Failed to load resource: the server responded with a status of 404 (Not Found)
SOLUTION:
Go to index.html of .net web api project, and replace the above files with project name like this
<head>
<link rel='stylesheet' href='/TestWebAPI/styles.3ff695c00d717f2d2a11.css'>
<head>
<script type='text/javascript' src='/TestWebAPI/runtime.932554c7e1000ee910b0.js>
Now the index.html will show the output in correct path

})
Issue 4 :-
when router-outlet is included in app.component.html with other html elements like div,paragraph etc.
Now run ng serve in command prompt.
After executing the site i saw,the output is blank.
for eg:- app.component.html
<div style='text-align:center'>
<h1>
welcome to Technology
<h1>
<h2>hello angular6'<h2>'
<div>
SOLUTION:-
ADD CUSTOM_ELEMENTS_SCHEMA IN APP.MODULE.TS
import { NgModule,CUSTOM_ELEMENTS_SCHEMA } from @angular/core;
@NgModule({
schemas: [CUSTOM_ELEMENTS_SCHEMA],
declarations: [
AppComponent
],
NOW AFTER RUNNING NG SERVE,YOU CAN SEE THE OUTPUT IN THE BROWSER.
