Xamarin.Forms - InitializeComponent doesn't exist when creating a new page

I'm using Visual Studio to try out Xamarin.Forms. I'm trying to follow the guide: http://developer.xamarin.com/guides/cross-platform/xamarin-forms/xaml-for-xamarin-forms/getting_started_with_xaml/

In short, I create a Xamarin.Forms solution using a PCL and then try to add a Forms XAML Page to the PCL-project.

The code-behind that gets created looks like this:

    public partial class Page1 : ContentPage
    {
        public Page1()
        {
            InitializeComponent(); 
        }
    }

The problem here is that InitializeComponent(); is red. When I try to build I get informed that The name 'InitializeComponent' does not exist in the current context

I've been looking around for solutions and even though others have had the same trouble, their solutions wont work for me. Here is one suggestion i tried to use: http://blog.falafel.com/xamarin-error-initializecomponent-does-not-exist-in-the-current-context/

Please let me know if you have a solution for this problem. Thanks!

Update:

My PCL (which is where I also want to add my XAML-page) contains:

App.cs:

    public class App : Application
    {
        public App()
        {
            // The root page of your application
            MainPage = new ContentPage
            {
                Content = new StackLayout
                {
                    VerticalOptions = LayoutOptions.Center,
                    Children = {
                        new Label {
                            XAlign = TextAlignment.Center,
                            Text = "Welcome to Xamarin Forms!"
                        }
                    }
                }
            };
        }

        protected override void OnStart()
        {
            // Handle when your app starts
        }

        protected override void OnSleep()
        {
            // Handle when your app sleeps
        }

        protected override void OnResume()
        {
            // Handle when your app resumes
        }
    }

And my XAML-page:

<?xml version="1.0" encoding="utf-8" ?>
<ContentPage xmlns="http://xamarin.com/schemas/2014/forms"
             xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
             x:Class="XamaTest.MyXamlPage">
    <Label Text="{Binding MainText}" VerticalOptions="Center" HorizontalOptions="Center" />
</ContentPage>

Code-behind:

    public partial class MyXamlPage : ContentPage
    {
        public MyXamlPage()
        {
            InitializeComponent();
        }
    }

UPDATE: This error doesn't usually appear in VS 2015, if it does, here's my original answer:

Found the solution! Right click on the .XAML file, select Properties.

You will see a Property called Custom Tool. Change its value from MSBuild:Compile to MSBuild:UpdateDesignTimeXaml

This will solve the problem. Dont know about the downvote, but here's my screenshot:

UPDATE:

It reappears rarely. If it does, just open the Xaml and code behind files and save them. I know, its not the best solution, but it gets the job done.

I get this sometimes and here's the checklist that solved them so far:

1. Make sure the namespace in .xaml and .xaml.cs match

2. Inherit from the correct parent - ContentPage for a page and ContentView for a control

3. Set build action of the .xaml file to Embedded Resource if in the shared project.

As far as my observation is concerned, in Visual Studio 2015, XAML properties are already set as suggested by highly-voted answers here by default, specifically :

• Custom Tool = MSBuild:UpdateDesignTimeXaml
• Build Action = Embedded Resource

but the error still appears sometimes... (like in this other question).

Editing the corresponding XAML file and then hit CTRL+S should work fine, but you don't have to. A cleaner way to force Custom Tools to be run is by right-clicking on the XAML file and then click on "Run Custom Tool" context menu.

I have met this problem. It's associated with the encoding of XAML files in VS. I'm using VS2015.

I solved this problem as follows:

1. Open the *.xaml file in the project and click Save button. (There will be applying the correct encoding in VS2015).

2. Then reopen the project and rebuild it. Now there are no errors.
