Hi @Artem ,
Welcome to Microsoft Q&A forum.
Several situations:
- Some controls are for other types of project(UWP, WPF, WinForms), so they are not available by default. Right-click the white space in Toolbox and uncheck "Show All". The available controls then appear.
- Something’s wrong when loading or detecting the controls. Try to right-click the white space in Toolbox, select "Reset Toolbox" to reset the toolbox.
- Make sure that you have opened the designer view of the form(right-click the Form.cs file, click View Designer).
- Try to restart Visual Studio.
- In case the issue is caused by Visual Studio, try to repair Visual Studio from Visual Studio Installer, More, Repair(this takes some time).
If the issue persists, please share us the complete steps that you performed, starts from creating the project. And if you can share us a complete screenshot of VS and your project structure, it will be useful.
Update1:
Try to use .NET Framework project to use the WebBrowser control. If you are using .NET project, the WebBrowser control is not available. You need to install NuGet package to use the WebView2 control instead.
See this thread: No WebBrowser Control in Toolbox Winforms .NET 6 for more details.
Update2:
Based on Artem's comment, restoring the app helped.
Best regards,
Tianyu
