Exception: Can't bind to 'ngFor' since it isn't a known native property

angular typescript angular2-directives ngfor

I missed let in front of talk:

<div *ngFor="let talk of talks">

Note that as of beta.17 usage of #... to declare local variables inside of structural directives like NgFor is deprecated. Use let instead.

<div *ngFor="#talk of talks"> now becomes <div *ngFor="let talk of talks">

Original answer:

I missed # in front of talk:

<div *ngFor="#talk of talks">

It is so easy to forget that #. I wish the Angular exception error message would instead say:
you forgot that # again.

angular typescript angular2-directives ngfor

Another typo leading to the OP's error could be using in:

<div *ngFor="let talk in talks">

You should use of instead:

<div *ngFor="let talk of talks">

angular typescript angular2-directives ngfor

This Statement used in Angular2 Beta version.....

Hereafter use let instead of #

let keyword is used to declare local variable
