You can use the new .createComponent() function.

import {ComponentRef, Injectable, Component, Injector, ViewContainerRef, ViewChild,ComponentResolver, DynamicComponentLoader} from '@angular/core';

    constructor(private dcl: DynamicComponentLoader, injector: Injector,private resolver: ComponentResolver) {}

...

    this.resolver.resolveComponent((this.createWrapper()).then((factory:ComponentFactory) => {
          this.cmpRef = this.theBody.createComponent(factory)
        });

and remove providers: [DynamicComponentLoader, Injector]
