Lock prevents users from deleting a storage account or modifying its configuration but permits reading the configuration.



User role Administrator and owner can modify the above two azure lock features.

Configure Azure Lock

We will see the following steps for how to configure azure lock using the Azure portal.

Step 1: Navigate to your storage account, or if you have not created it before, I have shared steps in my previous article about how to create an Azure storage account.



Step 2: On Storage account quick setting menu and Select on Lock, the lock list showing empty means, they are is no lock available on existing so click on Add for new lock configuration

Create new Lock

As mentioned above, Resource lock has two types, so select the Lock type as per your need and provide the lock name and description for understanding.



After clicking on Ok, You will get the following list screen with Lock Name, type, and Edit. Edit Options for Edit the name and type, delete option for deleting the lock associated with a storage account.

Resource Lock testing

You can navigate to Storage account and click on Delete



After clicking on the delete option, Immediately Azure intelligent will show the notification saying you can’t delete because of the Resource lock

Summary

You have learned now and How to Avoid Accidental Deletion of Azure Resource on the Azure Portal and available lock options. If you have questions, Keep continuing to post your comment below.

Azure selected four of these data services and placed them together under the name Azure Storage. The four services are Azure Blobs, Azure Files, Azure Queues, and Azure Tables

Visual Studio 2019 Preview

Visual studio 2019 early access preview version you can download from Microsoft website . This release is not "go-live" so not recommended to use on production computers or for creating production code.

Verify MAUI SDK Installation

Previously was install all the required SDK is manual, Now, Jonathan Dick has put together a useful dotnet tool that evaluates your system and gathers as many of the required pieces as it can. To get started, install maui-check globally from the command line.

Open Run CMD as an Administrator mode and install MAUI Check tool using the below line

dotnet tool install -g Redth.Net.Maui.Check



After MAUI check tool install, will start to execute the below the line of code to verify the SDK installation

maui-check



You need to install the Preview 2 version of the dotNet 6 SDK, as well as the Preview 2 Android, iOS, and Mac Catalyst workloads so if you are getting any error alert saying SDK is missing, keep give input as “Yes” for install the missing SDK and wait for the “Congratulations, everything looks great!” message, that means, you are ready to start the new MAUI application.

Create a new MAUI Mobile application

Visual Studio 2019 Preview version default available MAUI project template and select Create a new project, otherwise, you can download the default project sample available in the Git MAUI official repository.



Search for "MAUI" or choose Mobile from the Project type menu. Select the .Net Maui Mobile application



Choose a project name – the example uses "HelloMaui" and click on Create



Once you click on create button automatically solutions will generate. Before building the solutions, Let quickly understand all the folders and files.

MAUI Application Startup

Multi-targeted .NET MAUI Single Project for iOS and Android. .NET MAUI starts every application using Microsoft.Extensions HostBuilder.



Each platform has a different starting point, and the consistent point of entry for your application is Startup.cs will allow the following. It includes a Configure method to pipe service registration, handler registration

public class Startup : IStartup

{
public void Configure(IAppHostBuilder appBuilder)
{
appBuilder .UseMauiApp<App>();

}
}

Application customization processes, this is where you can do such things as register fonts and register compatibility for Xamarin.Forms renderers or your own custom renderers, By default, if you don't want to customize anything special, ignore this

appBuilder

.UseFormsCompatibility()

.UseMauiApp<App>()

.ConfigureFonts(fonts => {

fonts.AddFont("ionicons.ttf", "IonIcons");

})

MAUI Application Life cycle

.Net MAUI Application preview 3 Support to manage the life cycle of the application. Life Cycle API included in Startup.cs file and will write platform-specific.

public void Configure(IAppHostBuilder appBuilder)

{

appBuilder

.ConfigureLifecycleEvents(lifecycle => {

#if ANDROID

lifecycle.AddAndroid(d => {

d.OnBackPressed(activity => {

System.Diagnostics.Debug.WriteLine("Back button pressed!");

});

});

#endif

});

}

MAUI App.Xaml

In App.Xaml.cs project inherited by Microsoft.Maui.Controls.Application and make sure MAUI namespace added specify common Image directory for all the platform

using Microsoft.Maui;
using Microsoft.Maui.Controls.PlatformConfiguration.WindowsSpecific;

namespace HelloMaui

{

public partial class App : Microsoft.Maui.Controls.Application

{

public App()

{

InitializeComponent();

}
public override IWindow CreateWindow(IActivationState activationState)

{

Microsoft.Maui.Controls.Compatibility.Forms.Init(activationState);


this.On<Microsoft.Maui.Controls.PlatformConfiguration.Windows>()

.SetImageDirectory("Assets");


return new MainWindow();

}

}

}

In App.Xaml, will work same like xamairn form and will add all the common resources and style



<Application xmlns="http://xamarin.com/schemas/2014/forms"

xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"

xmlns:local="clr-namespace:HelloMaui"

x:Class="HelloMaui.App">

<Application.Resources>

<ResourceDictionary>


<!-- Add any additional resources here. -->

<Color x:Key="PageBackgroundColor">White</Color>


<Color x:Key="PrimaryTextColor">Black</Color>


<Color x:Key="GlyphColor">#2B0B98</Color>


<Style TargetType="Label">

<Setter Property="TextColor" Value="{DynamicResource PrimaryTextColor}" />

</Style>


<Style TargetType="Label" x:Key="Glyph">

<Setter Property="TextColor" Value="{DynamicResource GlyphColor}" />

<Setter Property="FontFamily" Value="IonIcons" />

<Setter Property="FontSize" Value="32" />

</Style>

</ResourceDictionary>

</Application.Resources>

</Application>

Application icon

The application icon is one great improvement, the AppIcon folder will available under the MAUI project and it is just a single SVG, Looks like Maui will just automatically take care of generating all the different icon sizes for different devices.

MAUI Design Screen

AssemblyInfo.cs file is removed from solutions. Main Page Name not changed. The xaml looks like below and you can observe below code the concept of SemanticProperties is added

<ContentPage xmlns="http://xamarin.com/schemas/2014/forms"

xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"

x:Class="HelloMaui.MainPage"

BackgroundColor="{DynamicResource PageBackgroundColor}">


<ScrollView>

<StackLayout Padding="{OnPlatform iOS='30,60,30,30', Default='30'}">


<Label Text="Getting started with MAUI Xamarin Forms Application using Visual Studio 2019 Preview 16.10"

SemanticProperties.HeadingLevel="Level1"

FontSize="32"

HorizontalOptions="CenterAndExpand" />

<Label Text="Welcome to .NET MAUI!"

HorizontalOptions="CenterAndExpand" />
<Image

Source="dotnet_bot.png"

SemanticProperties.Description="Cute dotnet bot waving hi to you!"

Margin="40,0" />

</StackLayout>

</ScrollView>

</ContentPage>

In MainPage.xaml.cs removed using Xamarin.Forms, add an inheritance from IPage, added the Maui namespace


using System;

using Microsoft.Maui;

using Microsoft.Maui.Controls;

using Microsoft.Maui.Controls.Xaml;


namespace HelloMaui

{

[XamlCompilation(XamlCompilationOptions.Compile)]

public partial class MainPage : ContentPage, IPage

{

public MainPage()

{

InitializeComponent();

}

public IView View { get => (IView)Content; set => Content = (View)value; }

}

}

Restore MAUI Nuget package

Before you will build and run solutions make sure NuGet packages referenced in the configuration file.

Right Click on Solutions > Open Folder in File Explorer



Make sure global.json and NuGet.config file available before building the solutions

MAUI global.json

global.json file look like below

{

"sdk": {

"version": "6.0.100-preview.3.21202.5",

"rollForward": "disable",

"allowPrerelease": true

}

}

MAUI Nuget.Config

Nuget.Config looks like the below and have the reference key for dotnet6,Xamarin, and public.

<?xml version="1.0" encoding="utf-8"?>

<configuration>

<packageSources>

<clear />

<!-- ensure only the sources defined below are used -->

<add key="dotnet6" value="https://pkgs.dev.azure.com/dnceng/public/_packaging/dotnet6/nuget/v3/index.json" />

<add key="xamarin" value="https://pkgs.dev.azure.com/azure-public/vside/_packaging/xamarin-impl/nuget/v3/index.json" />

<add key="public" value="https://pkgs.dev.azure.com/dnceng/public/_packaging/dotnet-public/nuget/v3/index.json" />

</packageSources>

<config>

<add key="globalPackagesFolder" value="packages" />

</config>

</configuration>

Build and Run MAUI Android App

Inside Android Folder, not find any MainActivity.cs, only available Resource folder and Androidmanifest file. You will need the Android SDK installed as well as Android SDK Platform 30. When you did a verified MAUI check, SDK was download and installed, if no, a simple way to get this is to install the current Xamarin workload and go to Tools > Android > Android SDK Manager from within Visual Studio.



Try to click on Run Icon, if you are getting any issue, Right-click on the solution and Select in the open terminal



Build the MAUI Project, run the below comment in the Visual studio terminal

dotnet build HelloMaui

You can launch the Android project to an attached emulator or device

dotnet build HelloMaui -t:Run -f net6.0-android

Once the build is successful, the Android emulator / on-device application will run like below 

Build and Run iOS Project in window machine

The build and debug .NET 6 iOS applications from Visual Studio 2019 preview. iOS folder is very clean, you can find Appdelegate.cs, Entitlements.plist, info.plist, Launchscreen.storyboard and Program.CS(Main.cs gets renamed Program.cs)



If while connecting Visual Studio to your Mac through XMA you are prompted to install a different version of the SDK, you can ignore that since it refers to the legacy one. Make sure Xcode 12.4 installed in mac machine,


You can launch the iOS project to an attached iOS Simulator. Initially not working for me run the ios app in windows after that start working.

dotnet build HelloMaui -t:Run -f net6.0-ios

Once the build is successful, the iOS simulator/ Device will show the output like below 

Summary

In this article, you learned about the setup Maui development preview environment and you said hello to Maui, Will share details in the next article for setup Visual Studio Code and Visual Studio for Mac. If you have any questions/ feedback/ issues, please write in the comment box

Azure AD B2C Feature
