Always google any error messages you get, there are lots of pages that explain the problem and solution, this is just one

The entity or complex type 'Categories' cannot be constructed in a LINQ to Entities query.[^]

You can search for more yourself

Solution 2

As the message says, what you're doing is not supported in LINQ to SQL.
Specifically, creating a new object Person.
There is a simple workaround though. Just convert the data to .ToList() or .ToArray() and after that you can do Select:

.ToArray().Select(i => new Person { ... });
