I have been studying creating custom user controls, and am about to start the "Hands-on" programming example.
However, it's as if it's introducing a new feature that wasn't explained in the text. Could someone clarify what is meant by changing the root namespace in the following:
"Create a Windows user control that ... <blah> <blah> <blah>
This control must make the data ... available to the form...
To share a Person structure between the control and the form, each project must be declared in the same namespace. By default, each project is created in its own root namespace. The easiest and best way to change this is to display the Project Properties dialog box and change the root namespace before building the project."
So - why exactly is changing the namespace necessary?
And what exactly would one change it to?
