What is the correct way to change the namespace of a WinForm form?

Question

I have a form that is currently in the wrong namespace:

MyForm.cs: namespace DirtyHowdoyoudo { public MyForm() { ... MyForm.Designer.cs: namespace DirtyHowdoyoudo { partial class MainForm { 

The form must be in the Bajingo namespace. What is the correct way to change the namespace of a form?

Note. Editing MyForm.cs to use the new namespace:

 MyForm.cs: namespace Bajingo { public MyForm() { ... 

makes the designer break down. I can edit the MyForm.Designer.cs code MyForm.Designer.cs manually:

 MyForm.Designer.cs: namespace Bajingo { partial class MainForm { 

But I am told by Visual Studio ( and SO users who suggest "use refactoring" ) so as not to manually edit the constructor file.

---

Mandatory filler material:

• I checked the properties window for the form, and there is no Namespace property:

  

• I tried just renaming it, and let Visual Studio refactoring hit:

  

  Except that Visual Studio wants to rename the namespace everywhere, in everything. I just want this form.

Answer 1

You can edit the constructor file. Stay away from the region with the inscription "Windows Form Designer generated code" and everything will be fine.

You need to click on the Show All Files icon at the top of Solution Explorer before renaming the form. If you do not, some support files will not be renamed.
