Windows 10 introduces the Universal Windows Platform UWP which has been reimagined and reinvented from a solid core of Windows 10 speed and reliability.
Windows 10 further evolves the Windows Runtime model introduced by Windows 8. As part of the core, the UWP now provides a common app platform available on every device wihdows runs Windows This means you can create a single app package that can be installed onto a wide range of devices. In addition, with that single app package, the Windows Store provides a unified distribution channel to reach all the device types your app developing windows 10 applications with c# pdf run on. In this wundows days instruction pdt course, you will learn how to build connected UWP style applications using C.
You will also learn how to create Modern style UI with rich user experience using XAML, use the MVVM pattern and various controls, access device hardware vidmate for windows 10 as the camera, create and windws Live Tiles and finally how to package and deploy your applications. The student will be familiar with modern C language features. Rakuto Kasai Building, Yokneam Ilit.

Visual Studio installs an additional Developer Mode package for you. When the package installation is complete, close the Settings dialog box.
It's time to start developing. You'll add a button control, add an action to the button, and then start the "Hello World" app to see what it looks like. In the Solution Explorer , double-click MainPage. If you don't see the Toolbox option, you can open it from the menu bar. An "event handler" sounds complicated, but it's just another name for code that is called when an event happens.
In this case, it adds an action to the "Hello World! The code uses some Windows APIs to create a speech synthesis object and then gives it some text to say. For more information on using SpeechSynthesis , see System. It's time to build, deploy, and launch the "Hello World" UWP app to see what it looks and sounds like. Here's how. Use the Play button it has the text Local Machine to start the application on the local machine.
View your app, which appears soon after a splash screen disappears. The app should look similar to this:. To close the app, click the Stop Debugging button in the toolbar. The app should look similar to this image:. To close the app, select the Stop Debugging button in the toolbar. Readers will learn how to:. This book will work for anyone who wants to develop Windows 10 applications.

Change the option on the debug location toolbar to run in the simulator, and then press F5 or click the green arrow to start debugging.
The mouse mode button takes you back out of touch mode to keyboard and mouse mode. Set location The screenshot commands are invaluable for the submission process, as you will see in Chapter They are also useful to create screenshots for building documentation, advertising your app on your web site, and so on. Long sold as a separate product from Visual Studio, it was part of the Expression suite. Make sure that you actually save the changes, as making changes in both without saving will result in concurrency problems.
To open your project in Blend, right-click on the MainPage. Blend will open the file you right-clicked on in Visual Studio. Nothing too exciting to report here. Think of this as a turbo-charged Visual Studio Toolbox. In addition to controls and panels that you can add to your page, you can add and modify styles, behaviors, and media. It also allows for easy addition of transitions for your visual states. Just like in Visual Studio, you can have a split view, all design, or all markup.
You can also load code files into the center pane. In addition to the simple items like Name and Layout properties like Width and Height, there are a host of properties that are difficult to set by hand in markup. Brushes, Transforms, and Interactions can all be set using the Properties panel.
This is helpful to see what the page will look like with data at design time instead of always having to run the app.
Blend for Visual Studio is an extremely powerful tool and it would take an entire book to discuss all of the features. My development workflow involves keeping both Visual Studio and Blend open at the same time, and I switch back and forth depending on what I am trying to accomplish. Explore Blend and see what works best for you. If you have been in the Microsoft space for a significant length of time, you might remember Visual Source Safe. In the. That is a lot of tooling when you are only looking for SCM.
This means that a single repository is the source of record, and all developers check their code in and out of this single repository. Later versions of TFVC include the capability to shelve work and create branches, providing some isolation for work in progress.
This means that every developer using Git has a full-fledged repository on his local machine with complete history and tracking capabilities. Many Git users especially in a team environment have a central repository in addition to their local repository. This frees the developer to spike different ideas, work on features independent of the rest of the team, and check in rapidly as often as they like without worrying about network latency or affecting other team members.
Which SCM system you choose to use is completely up to you. They both have their merits and there are many other SCM systems available to you as well that are very effective in what they do.
So why do I bring up Git specifically in this book? Because if you are a single developer creating a Windows 8 app, Git is custom tailored to you, and with Visual Studio and updated to Visual Studio , Git support is now included. There are entire books written about effectively using Git, so this is just a quick look into the Visual Studio integration, and not a treatise on DVCS.
Creating a new repository is as easy as clicking on the Create button in GitHub for Windows. Once Visual Studio is configured to use Git, any projects created inside an existing repo will automatically tie into the Git repo. There are also attributes on how Git should handle conflicts in project files. You will see changes that will be included in this check-in, excluded changes, and untracked files. The NuGet Gallery is the central package repository used by all package authors and consumers.
Rather than installing the tools on your development machine, the packages are installed at the solution level. This permits different versions to coexist on the same developer machine.
Another very large advantage to NuGet is that each package lists its dependencies in its package manifest. When a package is installed through NuGet, all of its dependencies are installed as well.
Yet another benefit of NuGet is the ability to create private NuGet package sources. At the time of this writing, NuGet will install the current version unless you specify a version.
Another benefit of using NuGet. NET in the search dialog. Merely click Install to install Json. Whereas traditional applications were developed with a wide range of tools but no real design guidelines and no expectations of performance, Windows 10 UWP apps must meet a series of expectations, both in terms of UI design and app performance. They are distributed through the Microsoft Store after a stringent certification process. Blend for Visual Studio helps build compelling UIs, Git provides security for your source code, and NuGet enables easy addition of packages and add-ons to Visual Studio.
In this chapter, we cover some of the core principles of Windows 10, including its architecture, all of the many parts of its apps in Visual Studio, the Model-View-ViewModel pattern, and navigation. All in the context of building your first Windows 10 UWP app. Much of the project should be familiar to you. This gives you greater control over what is available to your application as you can ensure that your users have APIs or other features that may be required in your application.
For now, we will just use the defaulted selections. Feel free to update the information such as description, copyright, and so on. UniversalWindowsPlatform and Universal Windows. These references provide the vast majority of functionality and must be included.
Throughout this book, we will add references to supplement the default features available to us. The tile images and splash screen graphics go in this folder, as well as any other images or assets that need to be packaged with your app when it is deployed. Click on one of the images in Solution Explorer such as Logo. Alternatively, you can have the content copied to the Output directory or run a custom tool, although you will not want to do that for the images. The actual manifest file is an XML file, but Visual Studio provides a nice GUI to work with the elements in the file, saving us from having to memorize the format or definitions.
Double-click on the Package. You can select the rotations as well as the minimum width. For the layout preferences, if all of the options are checked or none of them checked, as in the default , then all rotations are supported. If only some of the layouts are checked, such as Portrait and Portrait-Flipped, the app will not rotate when a tablet is changed from Portrait to Landscape.
If the hardware does not support rotation such as a traditional laptop , then the setting is essentially meaningless. The following section, Minimum Width, will be covered in detail in Chapter 5. The Resource Group is a name you can give to your application where all processes running under your application will appear under that name.
Visual Studio has the ability to generate the tile images based on a single image and will take that image and generate the tiles of each size. The splash screen is what is shown as your app is activated. The default image is the white box on a dark screen.
Select Splash Screen in the left rail to set a new splash screen for your app. By default, any images specified here should be stored in the Assets folder previously discussed.
Those capabilities will also be placed into the Settings charm under Permissions so that users can change their mind after installation. Many of these features are also covered in later chapters. The Packaging Tab The final tab, the Packaging tab, is for setting the packaging information.
We cover this in depth in Chapter We will spend a lot of time in the code-behind file throughout this book. For this example, we will simply comment out the following line of code in the OnLaunched event handler to turn off the frame rate counter. As in Chapter 1, we want to delete this page and add a new Basic Page to access the additional benefits of the SuspensionManager, NavigationHelper, and more. Remember to add the new Basic Page with the name MainPage.
For example, if you named your new page NewPage. Arguments ; to this: rootFrame. Navigate typeof NewPage , e. It is so popular that there are a host of open-source frameworks available, and the pattern has even spilled over from XAML to web developers. In this chapter, we just scratch the surface of the pattern, starting with a brief explanation of the parts. It is not the persistence layer such as database or web service but the object representation of your data.
The structure of this data is typically in the form of entities or data transport objects DTOs. The view shows data to the user and takes input from the user.
Often, MVVM proponents strive for zero code-behind. My opinion and this is not meant to start an architectural debate is that removing code from the code-behind is a pleasant side effect of implementing MVVM properly, but not the goal. But, either way, the view becomes very lightweight. There is typically a one-to-one correlation between windows and ViewModels in my code, but architectural differences exist, and your mileage may vary.
ViewModels should also be very lightweight and leverage other classes, such as commands and repositories, handle the heavy lifting. We need to have backing properties to handle INotifyPropertyChanged events as we will see in the next section. To create these properties, open Customer. This is to save on calls to the PropertyChanged event, as you will see in the next subsection. ComponentModel namespace. ComponentModel to the Customer class, and then add the interface and the event.
The resulting code is shown next with the property setters and getters omitted for brevity: using System. Add a using for System. CompilerServices as follows: using System. You can also include the empty string, which will ask the binding engine to refresh all bindings on the Custom object. For our purposes, we want the setters for each of the properties to call OnPropertyChanged when a value on the model is updated but not when it is set to the same value; hence the added check that we did in the previous step.
In real-world examples, you would have ObservableCollections discussed later in the book and probably more than one model type in your window. As we are just showing the pattern here, we are going to keep things very simple.
For starters, we want the ViewModel to instantiate an instance of the Customer class again, in a real app, this would come from a repository in the data access layer. First, add a using for the models. The RelayCommand class was added to our project when we added the Basic Page, and it takes care of a lot of plumbing that we would have to do ourselves if we created an instance of ICommand manually.
The command as you will soon see gets tied to an actionable UI element, such as a button or a menu option. We will bind the command in the next section. The second is optional and determines if the command is allowed to execute. We are only going to use the first parameter in this example. Add the namespace for the RelayCommand, App1.
Common: using App1. We could easily do that in the constructor for the ViewModel, but I like to do that in the getter so that the related code is grouped together. We are done with the ViewModel. Models; using App1. ViewModels; Then add the following line of code to the constructor: this. Once it finds one, it stops and then attempts to bind the element based on the Path and the found DataContext.
When we assign the DataContext to the entire view, everything will then use that specified source object. No more code is necessary in the code-behind! Each of these controls will look at the MainPageViewModel for the property MyCustomer and then look for the correct property on that object. This then binds these controls to the first and last name of the customer. Buttons also can leverage the command pattern. This gives a very clean implementation of the view and allows for separation of concerns all the way down.
That is because TextBox bindings, by default, are two-way. If the source changes, the view is updated; if the view changes, the source is updated. The rest of the code in this book does not use the pattern to keep the examples simple and clean, but I recommend that you spend some time learning the pattern so you can make an educated decision for yourself as to when it will help your architecture.
All Windows 10 UWP apps are single-page apps. This code was written for us when we created the new project from the Blank App template. Open App. If it is null, then the app is started fresh and not resumed or restored from termination and a new frame is created. If the content is still null, the app navigates to the Main Page the default start page for the app. Navigation is a bit of a misnomer here. This is not like going from one web page to another. It is really swapping out the contents of the frame with the contents of the new page.
Name it PageTwo. Notice the back button? That comes along for free as part of the Basic Page template. More on that shortly. This is the advantage of setting the DataContext at the window level instead of for each control. We can pass in any data object that has those properties and it will just simply work. To do so, open MainPage. Note that if we were sticking with MVVM, we would add a command for this, but to keep things simple and to match the rest of the examples in this book , we are just going to add an event handler in the code-behind.
To do this, open MainPage. This is the same frame that was created in App. The first parameter is required, and it requires the type of page that is to be loaded into the frame.
In our case, it is typeof PageTwo. The navigation framework will take this type, use reflection to create an instance of the page, and load it into the frame. The second parameter is optional and will be passed into the page that is being navigated to as the Parameter property of the NavigationEventArgs.
We added some defensive programming to pass in a new Customer instance in case there is an error along the way. Open PageTwo. We touched on the MVVM pattern and data binding. Finally, we covered the single-page nature of Windows 10 UWP apps and using navigation framework to load different pages into your app. In the next chapter, we will take a deep look into all of the controls available for Windows 10 UWP app development.
Controls provide a way for users to interact with your app. Panels hold the controls. Together, they help you define your UI. Using a Dark theme is typically more user- and battery-friendly for tablet-based applications. However, based on your application, the Light theme might create a better user experience. The best way to understand the themes is to see them in action.
This is because the control is set to use the Light theme. In the Light theme, controls are expecting a light background, so they are configured to use dark fonts. Panels covered in the next section must have their background set to use ApplicationPageBackgroundThemeBrush in order for RequestedTheme to take effect.
The type of panel determines the behavior of the contained controls as will be described. Conceptually, they are very similar to ASP. However, while ASP. To start, open MainPage. Next, add a Canvas. If you do so by dragging a control from the toolbox directly into the XAML editor, the resulting XAML will be very clean: If you do so by dragging a control from the toolbox onto the design surface in Visual Studio, there will be a lot more attributes set on the control, as the design surface interprets where the control is dropped.
For example, in my test app, dragging a control onto the design surface resulted in the following XAML: There are advantages and disadvantages to the different methods of adding controls.
The best option is to try them all and determine what works best for you. The Canvas. Left and Canvas. Top properties set the location of the Ellipse with respect to the left and top boundaries of the Canvas. In this case, the Ellipse is pixels to the right of the left margin and pixels down from the top boundary. Change the Fill property to "Red" to see the circle more clearly. You can place as many objects as you like onto the Canvas.
The second rectangle would partially cover the ellipse since it was declared after the ellipse in the XAML. You can define them using various measurements.
The most common way is to define the actual size: or to define the relative size of two or more rows: This code indicates that the second row will be twice as big as the first and will take up two thirds of the available space. The last way to define them is by declaring a size to be "Auto," in which case it will size to the largest object in that row or column. The second row is fit to the size of the rectangle. The next two rows divide the remaining space in the proportion and the rectangles are centered in each.
The image was cropped to make all of this more obvious. Notice that the relative sizes are shown e. In this example, we placed everything in the first column to save space in the figure. The first properties you might set are horizontalAlignment and VerticalAlignment. This is different from cascading style sheets CSS in web development, where the numbers are in top-right-bottom-left order. Padding refers to the space within a control between its border and its contents. No room is created between the objects, but you can easily add space by setting a margin.
You can add any control inside a stack, including another stack. The outer StackPanel consists of a Rectangle and an Ellipse stacked on top of another. The inner StackPanel has its orientation set to Horizontal the default is Vertical , and within the inner StackPanel are two somewhat smaller ellipses. Utilizing this panel will allow you to control exactly where you want elements. Technically, the Border control, like many other controls, can only have a single object as its contents, but that object can be something like a StackPanel that can in turn have many objects within it, greatly increasing the utility of the Border.
Almost too many choices. For simplicity, we assume that you are working in Visual Studio. Blend is a powerful tool for XAML design work for laying out controls, etc.
Dragging a control from the toolbox onto either the design surface or directly into the XAML source itself is a great way to add controls to your page. If your control needs a special namespace, Visual Studio will add it for you automatically if you drag the control into place. This chapter covers some of the more important controls and panels but does not endeavor to be exhaustive.
For example, text is typically displayed using a TextBlock control and is retrieved from the user with a TextBox control. Notice that the default position for a control is in Grid.
While it is best programming practice to specify the default as well, it is so common to assume 0 for a cell or row if not specified, that we show it that way here. Notice the squiggly underlining of the misspelled word and the options to correct or add to the dictionary or ignore. If you want to use text prediction on devices with a keyboard, you should use AutoSuggestBox. If you wanted to use the same example on a desktop, you would use the following XAML Notice that there are a few differences here.
First, you can use a query icon. There are many options or you can leave it blank if you want for this icon and you are able to see them if you allow Visual Studio to use auto-complete for you. Another difference is that there are three different event handlers that are attached to this control. The following code populates the Job Title suggest box.
Contains args. Add args. This is where we set the source for the auto suggestions.
