Go to your SSMS or whatever tool you use and run your queries from there. If you can get your output from there then you can translate it to code. If you look at the previous comments, everyone, in essence, is telling you to review your data model.
Entity Framework Core uses Language-Integrated Query (LINQ) to query data from the database. LINQ allows you to use C# (or your . NET language of choice) to write strongly typed queries.
LINQ to Entities provides Language-Integrated Query (LINQ) support that enables developers to write queries against the Entity Framework conceptual model using Visual Basic or Visual C#. Queries against the Entity Framework are represented by command tree queries, which execute against the object context.
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.
