I have been looking into linq for quite sometime now. I noticed that most examples do not include a straight link to a database.

here is what I have

Dim sqlconn1 As New SqlConnection("my database connection")
        Dim sqladaptor = New SqlDataAdapterDim db As DataContext = New DataContext(sqlconn1)
        db.Connection.Open()

however, I can not seem to use it this way and I noticed there was a mapping section.

db.mapping

how can I connect to my database using linq?

What I have tried:

read multiple articles including: How to: Connect to a Database - ADO.NET | Microsoft Docs[^] However, I just can not seem to populate the linq query appropriately to manifest the results I need.

Maybe this will be helpful, but it involves using the Database Explorer:
How to: Query a Database by Using LINQ - Visual Basic | Microsoft Docs[^]

And also: Using LINQ to SQL in Visual Basic[^]

Another option would be to load the data in a DataSet and query that with LINQ:
