title: How to open form designer in Visual Studio?
body: <p>I am attempting to create a Windows Forms app in C# in Visual Studio.<br></p>
  
  <p>Normally one can double click the <code>Form1.cs</code> file in the Solution Explorer in order to access the simple drag and drop designer.<br></p>
  
  <p>Unfortunately, it only opens up the code for the file.<br>
  <br></p>
