Hi everyone I have an issue with AOT compilation, when I use 'templateUrl' in an app-root component (in the angualr-starter it is 'app' component https://github.com/AngularClass/angular-starter/blob/master/src/app/app.component.ts), I get an error in a browser 'Error: Cannot find primary outlet to load', but if I use - template: '<router-outlet></router-outlet>' everything works fine. Could someone explain, why it doesn't work with 'templateUrl'.

hi all
how can i add more flags when typescript compile? I'm getting this errror when build dev "Class 'Subject<T>' incorrectly extends base class 'Observable<T>'.
Types of property 'lift' are incompatible.
Type '<T, R>(operator: Operator<T, R>) => Observable<T>' is not assignable to type '<R>(operator: Operator<T, R>) => Observable<R>'.
Type 'Observable<T>' is not assignable to type 'Observable<R>'.
Type 'T' is not assignable to type 'R'."
I just searching and found some suggestion here https://stackoverflow.com/questions/44810195/how-do-i-get-around-this-error-in-rxjs-5-x-in-typescript-2-4. Can anyone give me idea
Kevin Brightwell
@thanhnvpt_twitter the issue is your version of typescript I think
Shot in the dark, could someone a bit more knowlegable take a look at this: https://stackoverflow.com/questions/44834017/karma-and-angular2-mixing-isolated-and-non-isolated-tests-causes-runtime-injec. I'm at a bit of a loss.
@thanhnvpt_twitter I had same error, I just updated package.json "typescript": "2.3.4" and did npm install

thanks @Nava2 @bhnbhushanTPL
@bhnbhushanTPL currently my tyscript version is 2.4.1, Is it too new?
issue: When user copy-paste into text area from windows sticky note, special character like  gets added that's not visible while adding. When downstream system extracts the data, this special char is visible and creates issues while adding extract to powercenter .. I have implemented regex to restrict unwanted chars that seem not to work in this case. Any pointers?
