Can't bind to 'ngFor' since it isn't a known property of 'li'

The usage of *ngFor within the li or div element has changed .like an example given below states that #contact of contacts where #contact defines as local variable.

<li *ngFor="#contact of contacts"></li>

Instead of using #contact,kindly replace your code snippet with the following structure in order to declare local variables inside of structural directives.

<li *ngFor="let contact of contacts"

(click)="onSelect(contact)"

[class.clicked]="showDetail === true">

{{contact.firstName}} {{contact.lastName}}

</li>

Hope it will help you someDay.

Can't bind to 'ngModel' since it isn't a known property of 'input'

This error may occur at your end during the Angular2 development, specially during creation of two way binding using [(ngModel)] with your Input type.

To fix this error kindly use the following in app.module.js and import the namespace like given below:

import { FormsModule } from '@angular/forms';

@NgModule({

declarations: [

AppComponent,

FirstComponent

],

imports: [

BrowserModule,FormsModule

],

providers: [],

bootstrap: [AppComponent]

})

As soon as you add this into the above given file.it should start work as anticipated.

mark or make job as durable in Quartz .net?

Mark or make job as durable in Quartz .net?

 

This is the code segment to mark Job as durable in case you are not trigging through ITrigger.

public static ISchedulerFactory schedFact = new StdSchedulerFactory();
        IScheduler sched = schedFact.GetScheduler();

IJobDetail jobEOD = JobBuilder.Create<Facilities>().WithIdentity("Facilities").StoreDurably(true).Build();
                                        JobKey jobKey = JobKey.Create("Facilities");
                                        sched.AddJob(jobEOD, false);
                                        sched.TriggerJob(jobKey);

Exclude controllers methods from docs or swagger

If you would like to ignore controller’s action method from documentation or swagger ,kindly out an annotation just above an action method.

 [ApiExplorerSettings(IgnoreApi = true)]

Thanks

Problem Statement : Cannot launch program 'c:\Users\sachin.kalia\Documents\My Web Sites\duckType.ts'; setting the 'outFiles' attribute might help.

image

There was a problem during the development of typescript application was shown above.

It means after pressing F5 it doesn’t allow you to debug a program,In layman words there was a little confusion for compiler which file i should call first.

So to mitigate such issue just open launch.json file and change the path of "outFiles": [ "${workspaceRoot}/js/**/*.js" ], and give the correct path.

like I have given below: "outFiles": [ "${workspaceRoot}/out/**/*.js" ],

What I have replaced the actual path "outFiles": [ "${workspaceRoot}/js/**/*.js" ], to "outFiles":

Note : replaced “JS” with “OUT”.
