Retreiving Link Entitiy attributes from CRM 3.0

We have 2 methods to retreive information from CRM.

1. Using Fetch Statements
2. Using QueryExpressions

although we can use to join entities in queryexpression we cannot use it to retreive link entity attributes. we need to use Fetch statements to do this task.

Also if we are trying to retreive more then one link entities attributes from a fetch statement we need to use alias, else the fecth statements will not be executed properly. below you can find an example.
