The licenses.licx file contains licensing information about controls used in the your application. It is then compiled into the
App_Licenses.dll. It should be deployed along with your web site when
you deploy the project. If you need to regenerate the
App_Licenses.dll, right click the licenses.licx file in the solution
explorer and choose the “Build Runtime Licences” command.
