How to add a reference to System.Configuration?
I'd like to use an app.config file for app settings and I've found reference to the libraries that I think I want, but System.Configuration is not in my references. I do have the Microsoft.Bcl package loaded. What package do I need to load to get access to the app settings functionality?

AppSettings Reader for Xamarin and Xamarin.Forms
Reading app.config files in a Xamarin.Forms Xaml project
While each mobile platforms do offer their own settings management api, there are no built in ways to read settings from a good old .net style app.config xml file; This is due to a bunch of good reasons reasons, notably the .net framework configuration management api being on the heavyweight side, and each platform having their own file system api.
So we built a simple PCLAppConfig library nicely nuget packaged for your immediate consumption.
This library makes use of the lovely PCLStorage library
This example assumes you are developing a Xamarin.Forms Xaml project, where you would need to access settings from your shared viewmodel.
FOR FILESYSTEM APP.CONFIG
Initialize ConfigurationManager.AppSettings on each of your platform project, just after the ‘Xamarin.Forms.Forms.Init’ statement, as per below:
iOS (AppDelegate.cs)
Xamarin.Forms.Forms.Init();
ConfigurationManager.Initialise(PCLAppConfig.FileSystemStream.PortableStream.Current);
LoadApplication(new App());
Android (MainActivity.cs)
Xamarin.Forms.Forms.Init(this, bundle);
ConfigurationManager.Initialise(PCLAppConfig.FileSystemStream.PortableStream.Current);
LoadApplication(new App());
UWP / Windows 8.1 / WP 8.1 (App.xaml.cs)
Xamarin.Forms.Forms.Init(e);
ConfigurationManager.Initialise(PCLAppConfig.FileSystemStream.PortableStream.Current);
LoadApplication(new App());
Add an app.config file to your shared PCL project, and add your appSettings entries, as you would do with any app.config file
<configuration>
<appSettings>
<add key="config.text" value="hello from app.settings!" />
</appSettings>
</configuration>
Add this PCL app.config file as a linked file on all your platform projects. For android, make sure to set the build action to ‘AndroidAsset’, for UWP set the build action to ‘Content’
Access your setting:
ConfigurationManager.AppSettings["config.text"];
FOR EMBEDDED APP.CONFIG
Initialize ConfigurationManager.AppSettings on your pcl project like below:
Assembly assembly = typeof(App).GetTypeInfo().Assembly;
ConfigurationManager.AppSettings = new ConfigurationManager(assembly.GetManifestResourceStream("DemoApp.App.config")).GetAppSettings;
Add an app.config on your shared pcl project and ensure that Build Action:EmbeddedResource, and add your appSettings entries, as you would do with any app.config
The source code and demo app are available in github

Binding TextColor of label to a property in the viewmodel
I have a label and I want to dynamically bind the textcolor property of this label to a property in my viewmodel. I have two doubts - does the property in my viewmodel has to be of type string or Color? And how do I do this thing?
All the previously answered questions haven't worked for me even when I have tried using an IValueConverter.

How to acces object inside CarouselView Xamarin.Forms
I have a Xamarin.Forms app that displays a ViewFlipper (https://github.com/TorbenK/ViewFlipper) inside a CarouselView.
I would like the ViewFlipper to flip back to the front when changing pages inside the carousel. But I can't seem to figure out how to access the ViewFlipper.
I have the following working code:
public class CarouselContent
{
public string FrontImg { get; set; }
public string BackImg { get; set; }
}
public class MainPage : ContentPage
{
public MainPage()
{
var pages = new ObservableCollection<CarouselContent>();
var page1 = new CarouselContent();
page1.FrontImg = "page1Front";
page1.BackImg = "page1Back";
var page2 = new CarouselContent();
page2.FrontImg = "page2Front";
page2.BackImg = "page2Back";
pages.Add(page1);
pages.Add(page2);
var carouselView = new Carousel(pages);
Content = carouselView;
}
}
public class Carousel : AbsoluteLayout
{
private DotButtonsLayout dotLayout;
private CarouselView carousel;
public Carousel(ObservableCollection<CarouselContent> pages)
{
carousel = new CarouselView();
var template = new DataTemplate(() =>
{
//create page
var absLayout = new AbsoluteLayout();
//create images for the flipper
var frontImg = new Image
{
Aspect = Aspect.AspectFit
};
frontImg.SetBinding(Image.SourceProperty, "FrontImg");
var backImg = new Image
{
Aspect = Aspect.AspectFit
};
backImg.SetBinding(Image.SourceProperty, "BackImg");
//create flipper
var flipper = new ViewFlipper.FormsPlugin.Abstractions.ViewFlipper();
flipper.FrontView = frontImg;
flipper.BackView = backImg;
//Add flipper to page
absLayout.Children.Add(flipper);
return absLayout;
});
carousel.ItemsSource = pages;
carousel.ItemTemplate = template;
Children.Add(carousel);
}
}
I tried adding the ViewFlipper to the CarouselContent but I couldn't get that to work. Any ideas?

Change Hamburger Icon Xamarin.Forms Android
Good Morning. I'm struggling in finding a way to change the default hamburger icon in Xamarin.Forms Master-Detail Page on Android.
I tried both to change the icon for the master page (but it works just on iOS) and change it manually in the MainActivity.
I'm using the new FormsAppCompatActivity base class but I can't find a way to modify the ActionBarDrawerToggle as suggested at http://bit.ly/2gv3iZk and still use the ToolbarResource property from FormsAppCompatActivity.
I guess the problem in FormsAppCompatActivity base class.
Forms expect to inflate the ToolBar here from the ToolbarResource layout id. I also tried reproduce the OnCreate via reflection but nothing worked.

Wrong autowidth Label?
Hi, I have a strange problem about Label.
in my GridLayout, defined as:
<Grid x:Name="RowTest"
BackgroundColor="white"
RowSpacing="0" ColumnSpacing="0" MinimumHeightRequest="130" >
<Grid.RowDefinitions>
<RowDefinition Height="Auto" />
<RowDefinition Height="Auto" />
<RowDefinition Height="*" />
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto" />
<ColumnDefinition Width="*" />
<ColumnDefinition Width="Auto" />
</Grid.ColumnDefinitions>
<Label
x:Name="title"
FontAttributes="Bold"
Margin="18,8,8,0"
Grid.ColumnSpan="2"
TextColor="Black"
FontSize="24"
Text="Lorem ipsum" />
<BoxView
Margin="18, 0, 0, 0"
Grid.Row="1"
WidthRequest="30}"
HeightRequest="5"
BackgroundColor="Yellow" />
<Label Margin="18, 0, 0, 0"
Grid.ColumnSpan="2"
Grid.Row="2"
TextColor="Black"
FontSize="13"
Text="Lorem ipsum dolor sit amet " />
<Image
Aspect="AspectFit"
Grid.Column="2"
Grid.RowSpan="3"
VerticalOptions="Center"
WidthRequest="28"
HeightRequest="28"
Margin="0,0,18,20"
Source="ic_icon" />
</Grid>
I don't understand why, but the text in the first label (title) sometimes is cropped and the last word disappear, rather than show the text on two lines.
Example:
Label "title" with Text="Lorem ipsum dolor" in my app it shows only "Lorem ipsum"
Label "title with Text = "Lorem ipsum dolor sit amen" in my app it shows "Lorem ipsum dolor sit amen" (on two rows)
I hope I explain myself.
