How to Make Windows / Android / iOS Apps Using Xamarin Platform


Before writing applications, you’ll need to install the Xamarin platform on your Mac,PC, or both (if you’re using that setup)

See the articles on the Xamarin website at:

Creating an iOS App
If you’re interested in using Xamarin.Forms to target the iPhone, first become familiar with the appropriate Getting Started documents on the Xamarin website: 

This will give you guidance on using the Xamarin.iOS library to develop an iPhone application in C#. All you really need to do is get to the point where you can build and deploy a simple iPhone application on either a real iPhone or the iPhone simulator.


If you’re using Visual Studio, and if everything is installed correctly, you should be able to select File > New > Project from the menu, and in the New Project dialog, from the left select Visual C# and iOS and then Universal (which refers to targeting both iPhone and iPad), and from the template list in
the center, select Blank App (iOS).


If you’re using Xamarin Studio, you should be able to select File > New > Solution from the menu, and in the New Project dialog, from the left, select iOS and then App, and from the template list in the center, select Single View App. 


In either case, select a location and name for the solution. Build and deploy the skeleton application created in the project. If you’re having a problem with this, it’s not a Xamarin.Forms issue. You might want to check the Xamarin.iOS forums to see if anybody else has a similar problem:

Creating an Android App

If you’re interested in using Xamarin.Forms to target Android devices, first become familiar with the Getting Started documents on the Xamarin website: 

https://developer.xamarin.com/guides/android/getting_started/ 


If you’re using Visual Studio, and if everything is installed correctly, you should be able to select File > New > Project from the menu, and in the New Project dialog, from the left, select Visual C# and then Android, and from the template list in the center, select Blank App (Android). 


If you’re using Xamarin Studio, you should be able to select File > New > Solution from the menu, and in the New Project dialog, from the left, select Android and App, and in the template list in the center, select Android App. 


Give it a location and a name; build and deploy. If you can’t get this process to work, it’s not a Xamarin.Forms issue, and you might want to check the Xamarin.Android forums for a similar problem:

Creating a Windows App

If you’re interested in using Xamarin.Forms to target Windows, Windows Phone, or Windows 10 Mobile, you’ll need to become familiar with at least the rudiments of using Visual Studio to develop  Windows applications: 

http://dev.windows.com/ 


In Visual Studio 2017, if everything is installed correctly, you should be able select File > New > Project from the menu, and in the New Project dialog, at the left, select Visual C# and Windows. You’ll see a hierarchy under the Windows heading something like this:



.
The first Universal heading under Windows is for creating a Universal Windows Platform application that can target either Windows 10 or Windows 10 Mobile. Select that, and from the center area select Blank App (Universal Windows) to create a UWP app.  

The other two project types supported by Xamarin.Forms are under the Windows 8 header. The Universal item actually creates two projects—a Windows desktop application and a Windows Phone application with some shared code. For creating just a Windows application, choose Windows and then from the center section Blank App (Windows 8.1). For a Windows Phone application, choose Windows Phone and Blank App This creates a project that targets Windows Phone 8.1. 

These are the three project types supported by Xamarin.Forms.

You should be able to build and deploy the skeleton application to the desktop or to a real phone or an emulator. If not, search the Microsoft website or online forums such as Stack Overflow. 

All ready? If you can build Xamarin.iOS, Xamarin.Android, and Windows applications (or some subset of those), then you’re ready to create your first Xamarin.Forms application. It’s time to say “Hello, Xamarin.Forms” to a new era in cross-platform mobile development.

Microsoft's year of change

Microsoft's 2014 changes

On Feb 04, 2014, Satya Nadella was appointed as the new CEO of Microsoft, changing the future direction of Microsoft. The organization had to change, the technology industry itself changes everyday, technology is upgrade, reinvented or simply created from scratch. If an organisation is to thrive in the field of technology, it must adapt and most importantly, it must innovate staying constantly ahead of all it's competitors.

Microsoft's past success has been built on that ability to innovate. For 30 years they have led the creation of new technology, creating products that met consumer demand. Their technology facilitated better business, a trait that has seen them corner the enterprise technology market. That innovation is core to Nadella's appointment and is crucial for Microsoft as the company enters the next chapter in product innovation and growth. The forseeable future of technology will be cloud led, putting Microsoft in a strong position. Nadella was ultimately responsible for the companies strategic and technical shift to cloud, overseeing the development of one of the worlds largest cloud infrastructures, Windows Azure.

The future for Microsoft looks exciting, if not yet certain, but before we dream of flying DeLoreans and robot butlers, lets take a closer look at that past history that has taken Microsoft to where they stand today. Using the follow infographic developed by Firebrand Training, let us go on a whistle-stop tour looking at the history of Microsoft Technology.

We've all been there. We've used the same hard drive for more than 5 years until it suddenly decided to give out. Was it a virus? Was it a mechanical problem? You don't know. And you don't care because you're too angry. All those songs, all those picture collections and wallpapers you'd downloaded are gone! You've made a backup for some of them, of course, but not all. And who knows how old the DVDs are and if they will run properly. Ah, darn it! If only there was a way to recover the data from the dying hard drive...

Oh, wait, there is! There are many Linux distributions you can use in order to deal with this problem. Lucky for you, most Linux distributions have a live CD and can be used to recover the data. There are even distributions created specifically for the job, such as SystemRescueCD. This is the A-Team of operating systems. When you have a problem; when there is no way to solve it; when there is no one else to turn to and if you can operate SystemRescueCD, then you can use it. Don't worry about it, it's not that difficult. Although most Windows users faint at even the thought of using Linux, and even more so when they see the text-based user interface, like I said it's not that difficult to deal with the issue.

SystemRescueCD

SystemRescueCD is based on Gentoo Linux and uses the Xfce user interface (the same as Xubuntu, for example). Don't get too excited, though. Even though the OS has an GUI, that doesn't mean that you will be using a lot of it. In fact, you will mostly be typing commands in the terminal. But don't despair – you won't get lost (hopefully).

Even though it looks like your garden variety operating system, it's actually designed for data recovery alone. You can't use it as your only OS. This is what makes it perfect for the task of recovering your data from the hard drive. Since you don't know what the reason is for the hard drive's demise, if it's a virus and you use a Windows based system for recovery, you might end up destroying the recovery system as well. This is your best bet

Data Recovery

When you first boot SystemRescueCD, type startx in the shell to launch the GUI. After that, insert the recovery USB flash drive. It's important that the flash drive has enough memory to hold all the data you wish to extract and also to be formatted in the NTFS file format. FAT32 is just bad and if you have large files, you really won't have a good time with it.

After you've inserted the proper flash drive, type blkid -o list so the system identifies the drives. Next, use the command ntfs-3d in order to mount the NTFS partitions (the command is mount in case you were too stubborn and insisted on using FAT32 format). Then type ls/mnt to display the directories to be mounted. The commands ntfs-3d/dev/sdb1 /mnt/backupto mount the recovery USB in the directory and ntfs-3d/dev/sda2 /mnt/windows mounts the partition you want to recover.

After you've mounted both the partition you want to recover and the USB drive to the directories, you are free to copy the data. You can do that either by using the cp command or by using the GUI of SystemRescueCD. In the bottom there is a folder-looking icon that has e2 written on it. It will open the emeFM2 file system and enable you to copy the information using the GUI. It's pretty straightforward from there. Navigate to the directories and choose the data you would like to recover. After doing recovering the data, close the file manager and type the command shutdown -h now. This will shut down SystemRescueCD. If all went according to plan, you will have saved your data successfully. Now all you have to do is format your hard drive and install a fresh Windows (if it was a software problem) or replace the hard drive altogether. The important part is that you managed to save your data.
