Why can't I edit MenuStrip in C# Windows Form Apps?

Question

C++ / C#

I recently started learning c#. And I had a question:

why can't I edit the Menu Strip? In general, the maximum that I can do is to put the standard button layout.

Answer 1

Judging by the screenshot, you have created a NET 5 project.
Compared to the NET Framework, to add/edit elements, here you need to change the Items property of the control. You can use ToolStripMenuItem instead of buttons.
Also, when editing, make sure the project is not running.
