Linq2Db has a link https://linq2db.github.io/index.html which provides more information about how to create a POCO and create a table based on it.

As per the page, a simple POCO can go like this:

using System;
using LinqToDB.Mapping;

[Table(Name = "Products")]
public class Product
{
  [PrimaryKey, Identity]
  public int ProductID { get; set; }

  [Column(Name = "ProductName"), NotNull]
  public string Name { get; set; }

  // ... other columns ...
}

Then you need to configure the connection strings.
