<ObjectDataProvider x:Key="CustomerDataProvider" ObjectType="{x:Type local:}" />

in this code segment as discussed while typing this "{x:Type local:}" /> the intellisence should give a popup window which contain "CustomerDataProvider". but it is not coming in my case ie I want the code segment to be just like "{x:Type local:CustomerDataProvider}". Please help
