title: Form view designer is not working in Visual Studio 2019 with C# .NET Core 3.1
body: <p>When I am opening a Visual Studio project with VB.NET then the Form view designer is automatically opened, but when I open a new project with C# .NET Core 3.1 with Windows Forms then it is showing code of <em>form1.cs</em>.</p>
  <p>I tried to alternate from <a href="https://en.wikipedia.org/wiki/Microsoft_Visual_Studio#Other_tools" rel="nofollow noreferrer">Solution Explorer</a> as well from menu <em>View</em> → <em>designer</em> option, but it is still not showing a form. What is going wrong there?</p>
  <p>I made a Google search for this, but I did not find anything useful on this.</p>
  <p>Please check in the image that I'm getting during the opening project.:</p>
