Software development

C# is an object oriented, strongly-typed language. The strict type checking in C#, both at compile and run times, results in the majority of typical C# programming errors being reported as early as possible, and their locations pinpointed quite accurately.In C Sharp programming, however, that decision is made by the programmer who wrote the object, not by the programmer who instantiates the object and assigns it to a variable.C# is one of several programming languages that target the Microsoft CLR, which automatically gives it the benefits of cross-language integration and exception handling, enhanced security, a simplified model for component interaction, and debugging and profiling services.

M->Model V->View VM->View Model MVVM is nothing but architectural pattern used in software engineering.MVVM prescribes separating the nonvisual classes that encapsulate interaction logic, business logic and data from the visual classes that actually render things to the screen. This separation makes the code easier to maintain: first, it prevents the UI from becoming a monolithic class with display controls, interaction logic and business logic all stuffed in side by side; and second, it enables you to automate the testing of interaction logic and user interface mappings instead of relying on expensive, unreliable manual testing.  It also helps to facilitate a 'lookless' view, where the visual design can be changed without changing the code. In MVVM, instead of writing C# or Visual Basic code to directly set and get properties of controls in the view, you create a view model which represents the information being presented in the view, and use data binding to kee

The default  MetroWindow  is made up of following components: 1.Title bar 2.WindowCommand 3.Resize Grip  4.Window icon WindowCommand You can add your own controls to  LeftWindowsCommands  or  RightWindowsCommands  - by default, buttons have a style automatically applied to them to make them fit in with the rest of the  WindowsCommands . As of 0.9, you are no longer limited to just buttons, but any control. Be aware, you’re responsible for styling anything other than buttons.

To create metro ui you first have to install "Mahapps.metro" from NuGet.To install it right click on project and click on manage NuGet and type Mahapps.metro you will get this package you have to install from here.Now you are ready to create metro ui.Now open you Mainwindow.xaml and add one namespace like bellow xmlns:Controls="clr-namespace:MahApps.Metro.Controls;assembly=MahApps.Metro"  and replace  Window  to  Controls:MetroWindow Now your Mainwindow.xaml become <Controls:MetroWindow x:Class="ProjectName.MainWindow"           xmlns= "http://schemas.microsoft.com/winfx/2006/xaml/presentation"           xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"           xmlns:Controls="clr-namespace:MahApps.Metro.Controls;assembly=MahApps.Metro"           Title="MainWindow"           H eight="600"           Width="800">   <!-- your content --> </Con

Click on File > New > Project menu option one dialog box will be displayed. here in left panel you have to choose c#. in middle panel you have to choose WPF Application. Give the project a name in the name field and click the OK button. Bydefault two files are created,one is the XAML file which is Mainwindiw.xaml and the other is the CS file which is Mainwindow.cs. In mainwindow.xaml, you will see two sub-windows, one is the design window and the other one is the source window. In WPF application, there are two ways to design an UI for your application. One is to simply drag and drop UI elements from the toolbox to the Design Window. The second way is to design your UI by writing XAML tags . In mainwindow.xaml file, the following XAML tags are written by default. <Window x: Class="ProjectName.MainWindow" xmlns = "http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x = "http://schemas.microsoft.com/winf
