title: Join two tables in Linq to SQL
body: <p>Maybe a quite easy question but I'm new in Linq to SQL. I have two tables</p>
  
  <pre><code>User : UserId,name,Password,Email
  USER_TABLE: Id, UserId, FirstName,LastName......
  </code></pre>
  
  <p>I would like a query that gives for example: <code>userID=3</code> then give all the details <code>(FirstName,LastName etc)</code>
  How can I join these two tables? I would prefer <code>C#</code> code if it is possible!</p>
