1. Editor Window or Main Window: Here, you will work with forms and code editing. You can notice the layout of form which is now blank. You will double click the form then it will open the code for that.
2. Solution Explorer Window: It is used to navigate between all items in solution. For example, if you will select a file form this window then particular information will be display in the property window.
3. Properties Window: This window is used to change the different properties of the selected item in the Solution Explorer. Also, you can change the properties of components or controls that you will add to the forms.

You can also reset the window layout by setting it to default. To set the default layout, go to Window -> Reset Window Layout in Visual Studio Menu.
Now to add the controls to your WinForms application go to Toolbox tab present in the extreme left side of Visual Studio. Here, you can see a list of controls. To access the most commonly used controls go to Common Controls present in Toolbox tab.

Now drag and drop the controls that you needed on created Form. For example, if you can add TextBox, ListBox, Button etc. as shown below. By clicking on the particular dropped control you can see and change its properties present in the right most corner of Visual Studio.

In the above image, you can see the TextBox is selected and its properties like TextAlign, MaxLength etc. are opened in right most corner. You can change its properties’ values as per the application need. The code of controls will be automatically added in the background. You can check the Form1.Designer.cs file present in the Solution Explorer Window.
To run the program you can use an F5 key or Play button present in the toolbar of Visual Studio. To stop the program you can use pause button present in the ToolBar. You can also run the program by going to Debug->Start Debugging menu in the menubar.

Create a Windows Forms app in Visual Studio with C#

In this short introduction to the Visual Studio integrated development environment (IDE), you’ll create a simple C# application that has a Windows-based user interface (UI).

If you haven’t already installed Visual Studio, go to the Visual Studio downloads page to install it for free.

If you haven’t already installed Visual Studio, go to the Visual Studio downloads page to install it for free.

Some of the screenshots in this tutorial use the dark theme. If you aren’t using the dark theme but would like to, see the Personalize the Visual Studio IDE and Editor page to learn how.

Create a project

First, you’ll create a C# application project. The project type comes with all the template files you’ll need, before you’ve even added anything.

Open Visual Studio 2017.

From the top menu bar, choose File > New > Project.

In the New Project dialog box in the left pane, expand Visual C#, and then choose Windows Desktop. In the middle pane, choose Windows Forms App (.NET Framework). Then name the file HelloWorld .

If you don’t see the Windows Forms App (.NET Framework) project template, cancel out of the New Project dialog box and from the top menu bar, choose Tools > Get Tools and Features. The Visual Studio Installer launches. Choose the .NET desktop development workload, then choose Modify.

Open Visual Studio 2019.

On the start window, choose Create a new project.

On the Create a new project window, choose the Windows Forms App (.NET Framework) template for C#.

(If you prefer, you can refine your search to quickly get to the template you want. For example, enter or type Windows Forms App in the search box. Next, choose C# from the Language list, and then choose Windows from the Platform list.)

If you do not see the Windows Forms App (.NET Framework) template, you can install it from the Create a new project window. In the Not finding what you’re looking for? message, choose the Install more tools and features link.

Next, in the Visual Studio Installer, choose the Choose the .NET desktop development workload.

After that, choose the Modify button in the Visual Studio Installer. You might be prompted to save your work; if so, do so. Next, choose Continue to install the workload. Then, return to step 2 in this «Create a project» procedure.

In the Configure your new project window, type or enter HelloWorld in the Project name box. Then, choose Create.

Visual Studio opens your new project.

Create the application

After you select your C# project template and name your file, Visual Studio opens a form for you. A form is a Windows user interface. We’ll create a «Hello World» application by adding controls to the form, and then we’ll run the app.

Add a button to the form

Choose Toolbox to open the Toolbox fly-out window.

(If you don’t see the Toolbox fly-out option, you can open it from the menu bar. To do so, View > Toolbox. Or, press Ctrl+Alt+X.)

Choose the Pin icon to dock the Toolbox window.

Choose the Button control and then drag it onto the form.

In the Properties window, locate Text, change the name from Button1 to Click this , and then press Enter.

(If you don’t see the Properties window, you can open it from the menu bar. To do so, choose View > Properties Window. Or, press F4.)

In the Design section of the Properties window, change the name from Button1 to btnClickThis , and then press Enter.

If you’ve alphabetized the list in the Properties window, Button1 appears in the (DataBindings) section, instead.

Add a label to the form

Now that we’ve added a button control to create an action, let’s add a label control to send text to.

Select the Label control from the Toolbox window, and then drag it onto the form and drop it beneath the Click this button.

In either the Design section or the (DataBindings) section of the Properties window, change the name of Label1 to lblHelloWorld , and then press Enter.

Add code to the form

In the Form1.cs [Design] window, double-click the Click this button to open the Form1.cs window.

(Alternatively, you can expand Form1.cs in Solution Explorer, and then choose Form1.)

In the Form1.cs window, after the private void line, type or enter lblHelloWorld.Text = «Hello World!»; as shown in the following screenshot:

Run the application

Choose the Start button to run the application.

Several things will happen. In the Visual Studio IDE, the Diagnostics Tools window will open, and an Output window will open, too. But outside of the IDE, a Form1 dialog box appears. It will include your Click this button and text that says Label1.

Choose the Click this button in the Form1 dialog box. Notice that the Label1 text changes to Hello World!.

Close the Form1 dialog box to stop running the app.
