how to retrieve the latestdate inspected from a column
In our app a user can inspect an item and when it inspected the current date is entered into the table. For the same item someother can uninspect it this time nothing is inserted into the table. Another user can inspect it and current date is inserted I need to get the LatestDate Inserted..how to get this with Linq
Let say table name is Statuses and col name is LastdateInspected

Sounds like you want something like:
var query = db.Statuses
.OrderByDescending(x => x.LastDateInspected)
.FirstOrDefault();
That will return null if there are no entries, or the value with the latest LastDateInspected value otherwise (i.e. the first result, having ordered by the last date inspected latest-first).
That will get you the whole record, of course. If you only want the date, you can select the LastDateInspected column.
