Create your first WinForms app on .NET Core [2 of 3]

The Discussion

• 

  I'm running the latest update of VS2019 Professional and when I try to open the designer, it simply opens another copy of Form1.cs. VS2019 is still broken.

• 

  Can I run the same code in Mac?

  Edward: I experienced the same problem, but then I found Olia's September 30th blog post. She explains that it isn't automatically available in VS yet. You need to enable the designer, download and install the Windows Forms .NET Core Designer VSIX package. Read about it here: https://devblogs.microsoft.com/dotnet/introducing-net-core-windows-forms-designer-preview-1/

  I've created and published a free ProjectTemplate in the meantime. It includes a complete framework of a NetCore Forms application with customized menus, Splash and About Screen, MRUManager and Config:

  Hi,
  
  How can we use DataGridView (DataGrid in older version) control in .Net Core 3.0?
  I can not see many of the controls in the toolbox in the Windows Form application.
  
  Could you please suggest?

  When I double click Form1.cs nothing happens and I have latest Visual Studio 2019 installed. I also did Shift+F7 still nothing. Any tips?

• 

  @Rafal, for that, firstly, you need to upgrade your visual studio version to 16.5 which gives the Windows Form Designer preview option along with that, you also need to enable the "Use the preview Windows Form designer for .NET Core" option under the Tools -> Options -> Preview Features. and restart your visual studio. It will start working.

  I have VS Community and the Windows Forms Core option does not appear in Create a new project. I assume it's not available in Community?
