Help: change the 'Resource File Name' property

I changed the Form1 class name using the Property dialog box, because I thought this would properly rename the resources also as it is mention in the header file:

/// WARNING: If you change the name of this class, you will need to change the
/// 'Resource File Name' property for the managed resource compiler tool
/// associated with all .resx files this class depends on. Otherwise,
/// the designers will not be able to interact properly with localized
/// resources associated with this form.

...but it didn't. This is the exception I get when I try to run it in the debugger:

An unhandled exception of type 'System.Resource.MissingManifestResource' occured in mscorlib.dll

Additional information: Could not find any resources appropriate for the specified culture (or the neutral culture) in the assembly. Make sure "FormName.resources" was correctly embedded or linked into assembly "MdiApp".

...so how do I make these changes?

attention

What kind of answer is that?!!?
