    use LINQ to query a simple list of objects in the .NET framework
    use LINQ to create result objects from a query
    join sets of objects with LINQ
    access related tables in a database by using the relations defined in the data model
    iterate over related tables in a SQL query
    use multiple from clauses and the orderby clause and return unnamed result properties
    use the where clause to create logical relationships between tables
  • make a change in the database that is persisted to SQL
    create an object in an entity data model and persist that change to the SQL database
    check if an object exists in an entity data model, remove existing relationships to other data objects, and then remove it from the data model and the SQL database
