Welcome to the Desktop Guide for Windows Forms, a UI framework that creates rich desktop client apps for Windows. The Windows Forms development platform supports a broad set of app development features, including controls, graphics, data binding, and user input. Windows Forms features a drag-and-drop visual designer in Visual Studio to easily create Windows Forms apps.
Windows Forms is a UI framework for building Windows desktop apps. It provides one of the most productive ways to create desktop apps based on the visual designer provided in Visual Studio. Functionality such as drag-and-drop placement of visual controls makes it easy to build desktop apps.
With Windows Forms, you develop graphically rich apps that are easy to deploy, update, and work while offline or while connected to the internet. Windows Forms apps can access the local hardware and file system of the computer where the app is running.
Windows Forms for .NET provides new features and enhancements over .NET Framework. For more information, see What's new in Windows Forms for .NET 7. To learn how to upgrade an app, see How to upgrade a Windows Forms desktop app to .NET 7
Windows Forms is a UI technology for .NET, a set of managed libraries that simplify common app tasks such as reading and writing to the file system. When you use a development environment like Visual Studio, you can create Windows Forms smart-client apps that display information, request input from users, and communicate with remote computers over a network.
In Windows Forms, a form is a visual surface on which you display information to the user. You ordinarily build Windows Forms apps by adding controls to forms and developing responses to user actions, such as mouse clicks or key presses. A control is a discrete UI element that displays data or accepts data input.
Windows Forms contains a variety of controls that you can add to forms: controls that display text boxes, buttons, drop-down boxes, radio buttons, and even webpages. If an existing control doesn't meet your needs, Windows Forms also supports creating your own custom controls using the UserControl class.
Windows Forms has rich UI controls that emulate features in high-end apps like Microsoft Office. When you use the ToolStrip and MenuStrip controls, you can create toolbars and menus that contain text and images, display submenus, and host other controls such as text boxes and combo boxes.
With the drag-and-drop Windows Forms Designer in Visual Studio, you can easily create Windows Forms apps. Just select the controls with your cursor and place them where you want on the form. The designer provides tools such as gridlines and snap lines to take the hassle out of aligning controls. You can use the FlowLayoutPanel, TableLayoutPanel, and SplitContainer controls to create advanced form layouts in less time.
Many apps must display data from a database, XML or JSON file, web service, or other data source. Windows Forms provides a flexible control that is named the DataGridView control for displaying such tabular data in a traditional row and column format, so that every piece of data occupies its own cell. When you use DataGridView, you can customize the appearance of individual cells, lock arbitrary rows and columns in place, and display complex controls inside cells, among other features.
Connecting to data sources over a network is a simple task with Windows Forms. The BindingSource component represents a connection to a data source, and exposes methods for binding data to controls, navigating to the previous and next records, editing records, and saving changes back to the original source. The BindingNavigator control provides a simple interface over the BindingSource component for users to navigate between records.
You can create data-bound controls easily by using the Data Sources window in Visual Studio. The window displays data sources such as databases, web services, and objects in your project. You can create data-bound controls by dragging items from this window onto forms in your project. You can also data-bind existing controls to data by dragging objects from the Data Sources window onto existing controls.
Another type of data binding you can manage in Windows Forms is settings. Most apps must retain some information about their run-time state, such as the last-known size of forms, and retain user preference data, such as default locations for saved files. The Application Settings feature addresses these requirements by providing an easy way to store both types of settings on the client computer. After you define these settings by using either Visual Studio or a code editor, the settings are persisted as XML and automatically read back into memory at run time.
After you have written your app, you must send the app to your users so that they can install and run it on their own client computers. When you use the ClickOnce technology, you can deploy your apps from within Visual Studio by using just a few clicks, and provide your users with a URL pointing to your app on the web. ClickOnce manages all the elements and dependencies in your app, and ensures that the app is correctly installed on the client computer.
ClickOnce apps can be configured to run only when the user is connected to the network, or to run both online and offline. When you specify that an app should support offline operation, ClickOnce adds a link to your app in the user's Start menu. The user can then open the app without using the URL.
When you update your app, you publish a new deployment manifest and a new copy of your app to your web server. ClickOnce will detect that there is an update available and upgrade the user's installation. No custom programming is required to update old apps.
In this tutorial, you create a simple C# application that has a Windows-based user interface (UI). The app has a button that changes the text of a label. This simple app has all the components used for more complicated Forms programs.
You can refine your search to quickly get to the template you want. For example, enter Windows Forms App in the search box. Next, choose C# from the language list, and then choose Windows from the platform list.

After you select your C# project template and name your project, Visual Studio opens a form for you. A form is a Windows user interface. Create a Hello World application by adding controls to the form. Then run the app.
If the other tools are windows installer msi files, you can probably install them silently, see e.g Silent installation of a MSI package, so your application would launch processes by using Process.Start() to run msiexec.exe /qn firstSetup.msi and so on.
The "Burn" tool included in the Windows Installer Xml Toolkit (WiX) . It allows you to specify a set of packges which can be executables, msi files etc. and installs them, acting like a single installer. The bundle setup can use a GUI (called a bootstrap application).
Unless the installers for the other apps expose an API for automation, which is unlikely, then you would have to employ the Windows API to achieve your aim. You would have to use FindWindow to get the handle of the installer's top-level window, FindWindowEx to get the handle of appropriate child windows, e.g. text boxes and buttons, and then SendMessage to set text and click. This combination is very common so you would be able to find plenty of examples. The catch is that you'll actually have to run those installers multiple times to determine what windows you need to access and then test that your code works.
Yesterday I edited a form in Visual Studio's form designer. When I returned to it today, the designer shows nothing. I can open the properties window, select all the different constituent components and edit their properties, but they do not show up. The application builds fine and the form can be run as usual.
To help others who may have this issue.The problem is due to the class declaration in the Form1.cs file.Please ensure public partial class Form1: Form class is the first-class declared in the file. No other class declaration should be on top of this.
There are actually a few reasons that one might encounter this issue.At times, it can be due a problem within the VS IDE and the way it incorrectly manages file types and subtypes. It normally does a great job with this "automagically", but it can also make painful and unexpected mistakes.
If you right-mouse-click (RMC) your Project, and unload it (not your solution) you will be able to RMC it again and choose "Edit Project File". Once there, search for your Form name. In my case, I will search for Form1.cs, note the incorrect icon I saw in the Solution Explorer View, and the code describing my form, within the project file:
Save your project file, then RMC on your project name in the Solution Explorer, choose "Reload Project", and you will see the correct icon as expected, and once again be able to use the form in Design mode:
*Note: This issue shouldn't occur with default forms (named Form1, Form2, etc) and even in my case, it happened with a form I named other than the default form name. I used that name in this example, purely for illustrative purposes.
Edit 2: That other form has now fixed itself after coming back from lunch and unlocking my PC... Might be something to do with how that affects the display - everything shifts over to my right hand monitor when I do that.
This seems quite foolproof, although you sometimes have to jimmy it around a lot before it finally works. I know it has worked when I get both a vertical and horizontal scrollbar; the form is then further down the page.
