On modifying non clustered index on base table and converting it into covering index as follow

CREATE UNIQUE NONCLUSTERED INDEX [IX_OriginalTable_ID2] ON [dbo].[mySampleTable] ( [ID2] ASC )
INCLUDE ( [ID1], [SomeData] )
ON [PRIMARY]

Query optimizer again using this NON CLUSTERED index instead of clustered index on view
WHY query optimizer prefer to use this NC index instead of Clustered index with same structure on view ???

Hi,

After Creating index on base table in same sequence,refresh view then you get same result as before.
It still use the Index of the base table?
