I'm using Professional, and until the latest release, was able to use the remoted simulator. So it would seem there is no technical reason to limit it. Please tell me this isn't just a money-grabbing exercise from Microsoft?

Remoted iOS Simulator for Visual Studio in Windows requires Visual Studio Enterprise license which is costly. It will be better if we get this with Visual Studio Professional.

Reactive Programing: Binding to an Observable in Xamarin.Forms

≪ Previous: Remoted iOS Simulator for Visual Studio in Windows

I'm trying to figure out the best possible way to deal with observables in Xamarin.Forms. Thought I might share this here:

I created my own kind of binding to directly bind to observables.

<Entry Text="{o:Bind StringObservable, Mode=OneWay}"/>
<Entry Text="{o:Bind StringObserver, Mode=OneWayToSource}"/>
<Entry Text="{o:Bind StringSubject, Mode=TwoWay}"/>

Any constructive criticism is welcome.

≪ Previous: Reactive Programing: Binding to an Observable in Xamarin.Forms

My App creates dynamically a lot of Xamarin.Forms.Entry
List LstEntry= new List ();
foreach (FormSubTypeParameterDTO fsubTypeParameters in formSubTypeParameterDTO)
{
ParameterDTO parameterDTO = ParameterBLL.Get (fsubTypeParameters.IdParameter);
txtCampo = new Entry
{
//Name= "txt" + parameterDTO.Id.ToString(), //(Here´s the problem)
HorizontalOptions = LayoutOptions.FillAndExpand,
BackgroundColor = Color.Transparent,
TextColor = Color.Gray,
Placeholder = "Your name"
};
LstEntry.Add(txtCampo);
}

In other function, i need get the values of LstEntry looking for by Name (ex: LstEntry[0].FindByName("yyyy").
This is impossible because I cannot set the "Name" property in the fields of Entry type.

It would be nice to have this (since XF now supports .NET Standard 2.0).
It would be even better if the toolkit provides an easy way to port PCL projects to .NET Standard 2.0 projects.

Authenticating Users with Azure Mobile Apps

≫ Next: Creating a REST service

≪ Previous: .NET Standard 2.0 based XF template?

I've implemented authentication as shown in Authenticating Users with Azure Mobile Apps sample, and I'm trying to use Google to authenticate on Android. The problem is that after I enter my Google email and password, I just get a blank screen. I know it's using the redirect URI because that shows up in the server log. I have set up the credentials with Google as a web application, and the URI is https://appname.azurewebsites.net/.auth/login/google/callback

It looks like it is redirecting, but it never returns from the LoginAsync() method call in MainActivity.

Here is the streaming log from the app service. I've left out the authorization codes for the sake of brevity, and replaced them with [xxx]

Hi All

I'm looking for a good how to guide for creating a REST service that I can consume in my Xamarin forms project. I need to connect to a SQL database via a web service. If someone could point me in the direction of a good tutorial or step by step guide it would be greatly appreciated.

Many thanks

async task in viewmodel won't run my foreach loop and populate data

≪ Previous: I cant find the option to create a PCL Xamarin Forms, VS 2017 (v15.5) project.

Yes, I'm a noob and I have probably a silly question...

I'm populating a listview with my viewmodel and it works fine if I statically assign values, but when I try to run an async task which loops through a list to add the values it does not populate my listview.

Here's the code behind I'm using:
`
public class ViewModel
{
public ViewModel()
{
Task.Run(async () => { await GetCatsAsync(); });
}

    public List<SourceItem> Source { get; set; }

    public async Task GetCatsAsync()
    {
        List<groceryList> itemsT = new List<groceryList>(await App.GroceryRepo.GetAllCategoriesAsync());

        foreach (var groceryList in itemsT)
        {
            if (groceryList.CategoryHead)
            {
                this.Source.Add(new SourceItem(groceryList.Category.ToString()));
            }
        }
    }
}

public class SourceItem
{
    public SourceItem(string name)
    {
        this.Name = name;
    }

    public string Name { get; set; }
}`

And here's my xaml:
`
<ContentPage.BindingContext>
viewModels:ViewModel x:Name="ViewModel"
</ContentPage.BindingContext>

            <telerikDataControls:RadListView x:Name="listViewModelTest" ItemsSource="{Binding Source}" HeightRequest="200">
                <telerikDataControls:RadListView.ItemTemplate>
                    <DataTemplate>
                        <listView:ListViewTemplateCell>
                            <listView:ListViewTemplateCell.View>
                                <Grid>
                                    <Label Margin="10" Text="{Binding Name}" />
                                </Grid>
                            </listView:ListViewTemplateCell.View>
                        </listView:ListViewTemplateCell>
                    </DataTemplate>
                </telerikDataControls:RadListView.ItemTemplate>
            </telerikDataControls:RadListView>`

The list itemsT does retrieve data and it hits my foreach but does not populate my listview.

Any ideas?

Creating the button in AppDelegate does not work (does not rendered in the storyboard and throws an exception in Main.cs)

 `LoginButton  loginButton = new LoginButton (new CGRect (48, 0, 218, 46)) {
