Form1 Rename Problem in Visual Studio

If you create a Windows Forms project in Visual Studio 2022, it creates a Form1.cs file, a Form1.cs [Design] form, and a Form1.Designer.cs file.  You can then drag items from the toolbox onto the form or select the form and using the form properties window to add event handlers like OnPaintForm1, and the Designer will handle those actions appropriately.

However, if after creating the project, you immediately rename Form1.cs and its counterparts to, say, MyForm.cs, etc. and then drag items from the toolbox to the form or select the form and use the properties window to add event handlers, the Designer does not appropriately update the renamed form files or form design.

What I have to do is use the original Form1 files, add the tools and event handlers, and build the application.  After that, I can rename the files and they still work.

Is there a way to fix the problem of renaming first?
