This walkthrough shows how to create a traditional Windows desktop application in Visual Studio. The example application you'll create uses the Windows API to display 'Hello, Windows desktop!' in a window. You can use the code that you develop in this walkthrough as a pattern to create other Windows desktop applications.
The Windows API (also known as the Win32 API, Windows Desktop API, and Windows Classic API) is a C-language-based framework for creating Windows applications. It has been in existence since the 1980s and has been used to create Windows applications for decades. More advanced and easier-to-program frameworks have been built on top of the Windows API. For example, MFC, ATL, the .NET frameworks. Even the most modern Windows Runtime code for UWP and Store apps written in C++/WinRT uses the Windows API underneath. For more information about the Windows API, see Windows API Index. There are many ways to create Windows applications, but the process above was the first. 2006 suzuki rmz 250 manual free download.

Prerequisites
Create a Windows desktop project
Follow these steps to create your first Windows desktop project. As you go, you'll enter the code for a working Windows desktop application. To see the documentation for your preferred version of Visual Studio, use the Version selector control. It's found at the top of the table of contents on this page.

In this article, you'll use Visual Studio to create the traditional 'Hello World!' program. Visual Studio is a professional Integrated Development Environment (IDE) with many features designed for .NET development. You'll use only a few of the features in Visual Studio to create this program. To learn more about Visual Studio, see Getting Started with Visual C#.
Note
Your computer might show different names or locations for some of the Visual Studio user interface elements in the following instructions. The Visual Studio edition that you have and the settings that you use determine these elements. For more information, see Personalizing the IDE.
Create a new application
Start Visual Studio. You'll see the following image on Windows:
Select Create a new project in the lower right corner of the image. Visual Studio displays the New Project dialog:
Note
If this is the first time you've started Visual Studio, the Recent project templates list is empty.
On the new project dialog, choose 'Console App (.NET Core)' and then press Next. Give your project a name, such as 'HelloWorld', then press Create.
Visual Studio opens your project. It's already a basic 'Hello World!' example. Press
Ctrl + F5 to run your project. Visual Studio builds your project, converting the source code into an executable. Then, it launches a command window that runs your new application. You should see the following text in the window:

Start Visual Studio for Mac. You'll see the following image on Mac:
Note
If this is the first time you've started Visual Studio for Mac, the Recent projects list is empty.
Select New in the upper right corner of the image. Visual Studio for Mac displays the New Project dialog:
On the new project dialog, choose '.NET Core', and 'Console App' and then press Next. You'll need to select the target framework. The default is fine, so press next. Give your project a name, such as 'HelloWorld', then press Create. You can use the default project location. Don't add this project to source control.
Visual Studio for Mac opens your project. It's already a basic 'Hello World!' example. Press
Ctrl + Fn + F5 to run your project. Visual Studio for Mac builds your project, converting the source code into an executable. Then, it launches a command window that runs your new application. You should see the following text in the window:
Press a key to end the session.
Elements of a C# program
Let's examine the important parts of this program. The first line contains a comment. The characters
// convert the rest of the line to a comment.
You can also comment out a block of text by enclosing it between the
/* and */ characters. This is shown in the following example.
A C# console application must contain a
Main method, in which control starts and ends. The Main method is where you create objects and execute other methods.
The
Main method is a static method that resides inside a class or a struct. In the previous 'Hello World!' example, it resides in a class named Hello . You can declare the Main method in one of the following ways:
-or-
The parameter of the
Main method, args , is a string array that contains the command-line arguments used to invoke the program.

Input and outputC# Forms Tutorial
C# programs generally use the input/output services provided by the run-time library of the .NET Framework. The statement
System.Console.WriteLine('Hello World!'); uses the WriteLine method. This is one of the output methods of the Console class in the run-time library. It displays its string parameter on the standard output stream followed by a new line. Other Console methods are available for different input and output operations. If you include the using System; directive at the beginning of the program, you can directly use the System classes and methods without fully qualifying them. For example, you can call Console.WriteLine instead of System.Console.WriteLine :
