Setting the Rootpage in Xamarin.Forms - xamarin

Question

I'm having trouble setting the rootpage of my Application. I wasn't able to show the right page. The first Mainpage is the default from the start and the second MainPage there is the name of the page that I created. Here's my code.
App.cs
public App()
{
MainPage = new NavigationPage(new MainPage());
}
And here is the code of my the page that i want to set as root page.
MainPage.xaml
<?xml version="1.0" encoding="utf-8" ?>
<ContentPage xmlns="http://xamarin.com/schemas/2014/forms"
xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
xmlns:local="clr-namespace:XamarinDemoApp"
x:Class="XamarinDemoApp.MainPage"
xmlns:ViewModels="clr-namespace:XamarinDemoApp.ViewModels;assembly=XamarinDemoApp">
<ContentPage.BindingContext>
<ViewModels:MainViewModel />
</ContentPage.BindingContext>
<ListView ItemsSource="{Binding EmployeesList}"
HasUnevenRows="True">
<ListView.ItemTemplate>
<DataTemplate>
<ViewCell>
<StackLayout Orientation="Horizontal">
<Label Text="{Binding Name}"
FontSize="24"/>
<Label Text="{Binding Department}"
FontSize="18"
Opacity="0.6"/>
</StackLayout>
</ViewCell>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
</ContentPage>
This is the code behind my MainPage.xaml.cs
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using Xamarin.Forms;
using XamarinDemoApp.ViewModels;
namespace XamarinDemoApp
{
public partial class MainPage : ContentPage
{
public MainPage()
{
InitializeComponent();
NavigationPage.SetHasNavigationBar(this, false);
}
}
}
This is the Stack Trace field I get.

This is in the wrong place ...
NavigationPage.SetHasNavigationBar(this, false);
It should be
public App()
{
var mainPage = new NavigationPage(new MainPage());
NavigationPage.SetHasNavigationBar(this, false);
MainPage = mainPage;
}
