Material design component "is not a known element" in Angular2

I have a hybrid Angular1 and Angular2 application. In one of the Angular2 components that I route to, I want to use a Material Design Button. When I insert a button into the template like this `<md-button>foo</md-button>` the application starts crashing with this console message ``` Error: Template parse errors: 'md-button' is not a known element: 1. If 'md-button' is an Angular component, then verify that it is part of this module. 2. If 'md-button' is a Web Component then add "CUSTOM_ELEMENTS_SCHEMA" to the '@NgModule.schemas' of this component to suppress this message. ("<h1>Job</h1>[ERROR ->]<md-button>material</md-button>"): JobComponent@0:12 at TemplateParser.parse (http://localhost:3000/node_modules/@angular/compiler/bundles/compiler.umd.js:8321:21) ``` So, it might sound like it is case 1 in the message, but I have tried the advice given in this answer to add `MdButton` to the `imports` property of my `NgModule` (which already contained `MaterialModule.forRoot()` as adviced by the documentation) , but if I do, the whole application goes blank without errors in the console. Here is some of the relevant code ``` import { UIRouterModule } from "ui-router-ng2"; import { Ng1ToNg2Module, uiRouterNgUpgrade } from "ui-router-ng1-to-ng2"; import { MaterialModule, MdButton } from '@angular/material'; const upgradeAdapter: UpgradeAdapter = new UpgradeAdapter( forwardRef(() => XamFlowNg2Module)); uiRouterNgUpgrade.setUpgradeAdapter(upgradeAdapter); angular.module("xamFlow") .factory("consoleService", upgradeAdapter.downgradeNg2Provider(ConsoleService)); /* * Expose our ng1 content to ng2 */ upgradeAdapter.upgradeNg1Provider("restService"); @NgModule({ declarations: [ JobComponent, ], entryComponents: [ // Components that are routed to must be listed here, otherwise you'll get "No Component Factory" JobComponent, ], imports: [ CommonModule, BrowserModule, FormsModule, HttpModule, Ng1ToNg2Module, MaterialModule.forRoot() ], providers: [ ConsoleService, ImageService ] }) class MyModule { } upgradeAdapter.bootstrap(document.body, ["myApp"]); ```
