Interface inheritance

Question

Hi,

 

     I have two interface classes for two view models for example I have interface IbaseA and IbaseB. IbaseB have same interfaces as IbaseB and some extra interfaces.IbaseA class interface is implemented in Aviewmodel and IbaseB class interface is implemented in Bviewmodel.These view models bind to different user control.I want to remove duplicate code means interfaces and properties.So plz help me to find out the best way to do it with same example if possible.

 

Thanks
