About Wince Licence

Hi,

I have two mini2440 boards. And, i build an application with c#. So, my
Wince 6.0 platform (Nk.bin) was built via Platform Builder which was
downloaded by msdn. 

I want to ask that Do i need to have wince licence? Or,  is license
important in this case?

The lack of license will not prevent you from running applications.

You'll obviously need to install .net compact framework on the mini2440 to
get microsoft c# applications to run.

Have you tried it?
