Question

This is my function:

 Public Function GetAllEmployee() As List(Of Employees)
    Return DB.Employees.Select(Function(q) New With {q.EmployeeID, q.LastName,q.FirstName}).ToList()
End Function

I’m getting an error:

Value of type System.Collections.Generic.List(Of <anonymous type>) cannot be converted to System.Collections.Generic.List(Of NorthwindModel.Employees).

You’re instantiating an Anonymous object inside your select statement. Try using this:

Return DB.Employees.ToList()

EDIT: If you want to give back a list of objects with only those 3 properties, you can define a class containing those properties:

Public Class MyEmployees
    Public Property EmployeeId As Long
    Public Property FirstName As String
    Public Property LastName As String
End Class

Then return a list of that new class:

Public Function GetAllEmployee() As List(Of MyEmployees)
    Return DB.Employees.Select(Function(q) New MyEmployees With { .EmployeeId = q.EmployeeID, .LastName = q.LastName, .FirstName = q.FirstName}).ToList()
End Function
