Running the project in "older" browsers - for example, in IE 9, 10 and 11*

Tell me how to solve the problem of running in old browsers. How to connect a polyfills file?

[Belka383]

Solved the problem this way: 1 step: added the following lines of code to the file "boot.browser.ts":

/ IE9, IE10 and IE11 requires all of the following polyfills. /

import 'core-js/es6/symbol'; import 'core-js/es6/object'; import 'core-js/es6/function'; import 'core-js/es6/parse-int'; import 'core-js/es6/parse-float'; import 'core-js/es6/number'; import 'core-js/es6/math'; import 'core-js/es6/string'; import 'core-js/es6/date'; import 'core-js/es6/array'; import 'core-js/es6/regexp'; import 'core-js/es6/map'; import 'core-js/es6/weak-map'; import 'core-js/es6/set';

/IE10 and IE11 requires the following for NgClass support on SVG elements /

import 'classlist.js'; // Run npm install --save classlist.js.

/ Evergreen browsers require these. /

import 'core-js/es6/reflect'; import 'core-js/es7/reflect';

/ Date, currency, decimal and percent pipes. Needed for: All but Chrome, Firefox, Edge, IE11 and Safari 10 /

import 'intl'; // Run npm install --save intl.

/ Need to import at least one locale-data with intl./

import 'intl/locale-data/jsonp/en';

2 step: open PowerShell in root folder the project and run: -> npm install --save intl -> npm install --save classlist.js -> npm install --save core-js

3 step: run your project

Good luck!

or created new file 'ClientApp/boot.polyfills.ts', paste the code, run npm install, and import in boot.browser.ts: import '../ClientApp/boot.polyfills';
