About Xamarin in this release:

Visual Studio Tools for Xamarin

This release includes Xamarin.iOS 11.8 and Xamarin.Android 8.2.

Live XAML Previewing with the iOS Simulator

The Xamarin Live Player enables developers to continuously deploy, test, and debug their apps using just Visual Studio and an iOS or Android device. Visual Studio 2017 version 15.5 added support to enable developers to preview real-time XAML changes directly in the Android emulator without requiring a recompile or redeploy. This release brings this functionality to the Remoted iOS Simulator for Windows.

Visual Studio 2019 Preview 2: Great news for Xamarin

May 27, 2019 | News | No Comments

Microsoft has released a new preview version of the new Visual Studio 2019.

The good thing is that it can be installed without affecting your current Visual Studio installation, so if you want to try it now, you can install it for free from here.

We love Visual Studio but in particular we love Xamarin, so let’s see what are the news related to it:

Build and Deploy time

It seems that this new version of Visual Studio brings a massive improvement in Build and Deploy time.

According to Pierce Boggan: “Incremental build times in the Visual Studio 2019 Preview for the SmartHotel360 app are 29.66% better than the Visual Studio 2017 version 15.8 release, and deployment times are over twice as fast“

STEP	VISUAL STUDIO 2017 VERSION 15.8	VISUAL STUDIO 2019 PREVIEW 2	DELTA
First Build	01:04.20	00:50.13	-21.95%
Incremental Build (XAML Change)	00:10.62	00:07.47	-29.66%
Deploy (XAML Change)	00:09.03	00:04.44	-50.83%

Considering that we spend most of our days building and deploying apps, even few seconds are more than appreciated and here we are talking about 30%. Not bad!

Enhanced Fast Deployment for Android

Visual Studio 2019 Preview 2 adds support for enhanced fast deployment. It means that it will generate a new APK only when necessary.

To enable this feature, add these lines to your Android file project:

<PropertyGroup>   
<AndroidFastDeploymentType>Assemblies:Dexes</AndroidFastDeploymentType> 
</PropertyGroup>

Xamarin.Forms

In Visual Studio 2019 we can use a property panel to help us writing our XAML files. We just need to select a control and all its properties will appear in the property panel.

XAML IntelliSense

Visual Studio 2019 has a better IntelliSense and will include IntelliCode that will recommend us the common items putting them on top of the completion list according to the context.

Designers

The Android designer adds support for Android Pie (9.0) while now IntelliSense is supported for Android XML files.

The iOS Designer adds support to render custom controls that need to load native dynamic libraries or frameworks.

What else

Visual Studio 2019 produces faster Android Apps with smaller APKs thanks to d8 and r8.

To enable these two features add these lines to your Android project file:

d8:

<PropertyGroup>   
<AndroidDexTool>d8</AndroidDexTool>
</PropertyGroup>

r8:

<PropertyGroup>   
<AndroidLinkTool>r8</AndroidLinkTool>
</PropertyGroup>

Visual Studio 2019 also adds the Xamarin Forms Shell Template.

There are many other improvements to Visual Studio 2019, so I’ll suggest you to try it and maybe give your feedback to Microsoft.

Safe Photo 2: A Xamarin.Forms app for Android, iOS and Windows

May 26, 2019 | Article, News | No Comments

On September 2013 I released Safe Photo a native application for Android that allows you to hide pictures on your phone.

The app was quite successful with over 100.000 downloads and an impressive rating of 4.1.

During these years I’ve stopped to write native apps to concentrate entirely on Xamarin. So the logic consequence of that is that I’ve now created a new version of the app with Xamarin.Forms: Safe Photo 2.

The idea behind the app is always the same: Safe Photo 2 will allow you to hide your secret pictures behind the security of the app.

Features

Protect the photos on your smartphone or tablet
Take new photos directly from the application, they will be protected automatically
Import photos from the public gallery (then delete them from the public gallery)
Protect your privacy with a numeric password
Organise your photos in galleries
Share your photos with whoever you want and how you want
The application can run on an external memory card so you will not consume the internal memory of your smartphone
Your photos are invisible also connecting the phone to a PC
Delete one or more images or galleries in one click
Compatible with smartphones and tablets
And it’s free

Gallery

Xamarin : How the app is made

To store all the data, Safe Photo 2 uses a SQLite database and of course the app uses the Sqlite Plugin For Xamarin And Windows (Nuget package).

The app also uses a Google Admob to show ads as banners and interstitials. As soon as possible I’ll create a package to easily add Admob to your Xamarin applications. If you prefer to write code yourself instead of using the plugin, I’ll also add a tutorial on how to add Admob on Xamarin.Android, Xamarin.iOS and Ads on UWP.

The app also uses some Dependency Services to execute some code on the native platforms. We use them to

Share a picture
Save, Copy and delete Files
Implement banners and interstitials for Admob

Do you want to know more about the app code or about Xamarin? Let me know and I’ll tell you more.

We added support for the range-v3 library with the MSVC 15.9 compiler.
We fixed several bugs in the F# compiler and F# tools.
Language service support for new TypeScript features for semantic file renaming and project references.
Improved Node.js development by updating Vue.js templates and adding support for unit testing using the Jest framework.
We added SharePoint 2019 project templates, so you can migrate existing SharePoint 2013 and 2016 projects to SharePoint 2019.
Visual Studio Tools for Xamarin now supports Xcode 10.
We made improvements to the Xamarin.Android build performance.
We have added and improved features for Universal Windows Platform developers, including ARM64 support, the latest preview SDK, better debugging of Desktop Bridge applications, and XAML Designer improvements.
Substantial improvements were made to the experience of using authenticated package feeds.
There is now support for lock file to enable repeatable restore for PackageReference based projects.
We have added support for the new license format for NuGet packages.
We have introduced NuGet client policies in Visual Studio which enables you to lock down environments such that only trusted packages can be installed.
We made the use of .NET Core within Visual Studio more predictable.

and these are the bugs fixed in this version:

No way to change “Find All References” background color.
“Visual C++ Resource Editor Package” load failed.
VS2017 v15.8 Build does not start if XAML files are not manually saved first.
Installation failed – manifest signature verification failed.
Update 15.8.6 breaks Installer Projects.
Scrolling up with the arrow key causes Visual Studio to page up.
After updating to 15.8.1, data tip does not show when debugging.
System.InvalidProgramException: Common Language Runtime detected an invalid program..
Solution Explorer does not remain pinned after closing Visual Studio.
Navigation bar in editor has trouble handling long method names.

Regarding Xamarin these are the most important changes in this release:

Visual Studio Tools for Xamarin

Visual Studio Tools for Xamarin now supports Xcode 10, which allows you to build and debug apps for iOS 12, tvOS 12, and watchOS 5. See how to get ready for iOS 12 and our introduction to iOS 12 for more details on the new features available.

With each update to Visual Studio 2019, we will continue implementing more of the features that were previously available in the XAML Designer for .NET Framework WPF applications.

Xamarin

We have updated the default Android Experience to API 28 for templates, device creation, installers, and more.
IntelliSense on Windows now shows recommendations for design-time attributes when writing Xamarin.Forms XAML.

Changes related to Xamarin

As we have seen, there are 2 main changes. The first one is relative to Android, now everything is updated to API 28, so we should find updated Android templates.

The second change is relative to IntelliSense, now it should give us better recommendations when we write our Xamarin.Froms XAML files.

A very annoying bug has been fixed in Xamarin.iOS: Xamarin.iOS cannot find the application manifest. Please ensure the project contains a manifest file named ‘Info.plist”.

That was quite a bad bug and the only way to resolve it was to unload and reload the iOS project. Fortunately now Microsoft has fixed it so…..Yeahhh!

Are you going to update Visual Studio? I’m doing it right now!

Xamarin.Forms 4.0 is finally out

May 22, 2019 | News | No Comments

Every release of Xamarin.Forms improves the performances and adds new features. It has been a long time since the first Xamarin.Forms came out. That version was very basic and to be honest not very great. Then Xamarin.Forms 2 came out and it was better, finally something that could be used for a production app. When Xamarin.Forms 3 came out, it was great, better performances, new features. Xamarin.Forms 3 has been a great tool to create amazing multiplatform apps and now Xamarin.Forms 4.0 promises even more, again better performances and new features. Let’s see together the main news of this release.

The Shell

Shell is a new way to create our apps. First of all it allows us to add easily flyouts and menus to our apps. It also adds the concept of URI navigation.

That’s great but what is even better is that it uses “fast renderers” (see later). To use the shell, on Visual Studio 2019 starting a new Xamarin.Forms app, you can select the Shell template. To get more info about Shell, you can use this documentation:

Android Fast Renderers

Android Fast Renderers were introduced in Xamarin.Forms 2.4 but disabled by default. The idea behind them is to reduce the number of views required to render a particular control. Honestly you could see improved performances so now they are enabled by default. This means that you will notice better perfomances with the enw Xamarin.Forms.

Image Source Unification

From Xamarin.Forms 3.5, they have introduced the FontImageSource to use the font glyphs but was not possible to use it everywhere. From version 4.0using ImageSource you can use them wherever you want.

Accessibility

From Xamarin Forms 4.0 we can now control the focus order directly in X.F. To do this, we can use the TabIndex property available on any VisualElement.

Conclusion

I will personally test Xamarin.Forms 4.0 and in particular the Shell to see how great that is. I will also test the new navigation pattern (URI Navigation) to see if there are improvements here. I will also evaluate the new performances to see if the app can be faster or more fluid.

And what do you think about Xamarin.Forms 4.0?

Native Crash with Syncfusion and Xamarin.Forms

May 21, 2019 | News | No Comments

If you are using the Syncfusion library together with Xamarin.Forms > 3.4 you should definitely continue to read.

Since the new release of Xamarin.Form 3.5, if you try to use the Syncfusion Listview (SfListView) in Release mode on Android, your app will crash.

In this moment there are two things that you can do:

Use a version of Xamarin.Forms < 3.5
Set the Linking to None (in this case your final APK will be bigger than usual).

Unless you are using some of the new features of Xamarin.Forms > 3.4, I’d suggest you to continue to use Xamarin.Forms 3.4 otherwise in you Android project, set the Linking to None and it will solve your problem.

I will update this post, as soon as Synfusion and Xamarin will solve this massive issue.

Meanwhile you can follow the progress of this bug here: https://github.com/xamarin/Xamarin.Forms/issues/5288

Python projects support type hints in IntelliSense, and a Run MyPy command has been added to look for typing errors in your code.
Conda environments are supported in Python projects.
We added a next version of our Python debugger based on the popular open source pydevd debugger.
TypeScript 2.8 is included in Visual Studio version 15.7.
We improved Kestrel HTTPs support during debugging.
We added support for JavaScript debugging with Microsoft Edge.
The Debugger supports VSTS and GitHub Authentication for Source Link.
IntelliTrace?s step-back debugging feature is supported for debugging .NET Core projects.
We added IntelliTrace support for taking snapshots on exceptions.
We removed the blocking modal dialog from branch checkouts in Git when a solution or project reload is not required.
There is an option to choose between OpenSSL and SChannel in Git.
You can create and associate Azure Key Vaults from within the Visual Studio IDE.
Visual Studio Tools for Xamarin can automatically install missing Android API levels required by Xamarin.Android projects.
The Xamarin.Forms XAML editor provides IntelliSense and quick fixes for conditional XAML.
We added support for Azure, UWP, and additional project types in Visual Studio Build Tools.

We added support for NuGet package signatures.
We added Service Fabric Tooling for the 6.2 Service Fabric release.
We updated Entity Framework Tools to work with the EF 6.2 runtime and to improve reverse engineering of existing databases.

And now let’s see the improvements around Xamarin:

Performance

In this release, we improved solution load time for C# and VB projects by an average of 20%.

Visual Studio Tools for Xamarin

This release includes Xamarin.Android 8.3 and Xamarin.iOS 11.10.

Automatic Android SDK Management

When a Xamarin.Android project is loaded, Visual Studio can determine if the Android API level used by the project is missing from your machine and automatically install it for you in the background. To enable this feature, go to Tools > Options > Xamarin > Android Settings > Auto Install Android SDKs.

Improved XAML IntelliSense

Xamarin.Forms developers using Visual Studio 2017 version 15.7 will notice a vastly improved IntelliSense experience

Automatic iOS Provisioning

We made iOS device provisioning for development easier. In Visual Studio 2017 version 15.7, there’s a streamlined experience to request a development certificate, generate a signing key, add a device in the Developer Center, and create a provisioning profile, all with a single button click. All the heavy lifting of provisioning an iOS device is handled for you in less than 30 seconds.

I really think you should update Visual Studio to the new version 15.7. The improvements around Xamarin are really impressive and very useful.You can read all about the new update here: https://docs.microsoft.com/en-gb/visualstudio/releasenotes/vs2017-relnotes

IMPORTANT: Visual Studio 15.6.5 adds support for Xcode 9.3

May 18, 2019 | News | No Comments

Today Microsoft has released a new version of Visual Studio to add support for Xcode 9.2

This is a FUNDAMENTAL update for Visual Studio and Xamarin as with the old version you cannot compile code for Apple (you can read the?article here).

Let’s see now the complete

Release notes:

VS 15.6 does not respect the ‘apply server settings to all users (store in project file)’.

Project could not be opened because Visual C# 2017 compiler was not created.

NuGet Package Manager only sees latest package versions after manually clearing cache.

Lost IIS Server Settings.

Visual Studio hangs during Nuget package update.

Installer throws unexpected error and saved changes to Solution2.sln are not saved.

C:\\Windows\\temp?fills up with .itrace files after upgrade to 15.5.6.

vstest.console.exe?fails test run with socket exception.

This release includes support for Xcode 9.3.

There are a couple of important issues fixed in this release but definitely the support for Xcode 9.3 is the most important feature of this update.

You can update Visual Studio going on Help -> Check for Updates or you can install Visual Studio from here: https://www.visualstudio.com/downloads

By Marco Troncone

IMPORTANT: Xcode version 9.3 is not yet compatible with Xamarin. Don’t update

May 17, 2019 | News | No Comments

UPDATE 4/4/2018: Microsoft has released the version 15.6.5 for Visual Studio that adds support for XCode 9.3. You can read more here.

The current Xamarin tool for Visual Studio 15.6.4 is not compatible yet with Xcode 9.3 so if you update Xcode to this version, you will not be able to compile your iOS projects anymore.

In case you are still using the Xcode version 9.2, disable the auto update.

If your mac has already updated Xcode to the new version 9.3 and you need to compile your projects for Apple, then you need to uninstall Xcode 9.3, disable the auto update and install Xcode version 9.2.
