First i increase size of datafaile by 500 Mb but i recieved same error , but next time when i increased same by 1 MB it worked. Thanks
In one of blogs i found this as well
"According to Microsoft, the problem was "DBCC SHRINKFILE was unable to run on the primary data file of the user database "DatabaseName" because a background operation which had obtained a latch for the required shrink operation previously was not released."
