Hola a todos.

Estoy trabajando en Visual Basic .Net

Hice un user control, con la Web Client Factory

Y una p?gina (tambi?n con la Web Client Factory), donde uso ese user control

Cuando quiero correr la p?gina, me sale este error:


[NullReferenceException: Object reference not set to an instance of an object.]
