I guess those tools can be useful in a simple db scheme. My problem with them is once you get beyond simple. Such as dealing with highly normalized db were getting something like a persons name, address and phone could possible take querying 4 or more tables. Or things like queries across different db or even linked servers.
Anyway to get some what back "On Topic" here is an example of the only comments in her code,
Code:
/// <summary>
/// There are no comments for AudienceSet in the schema.
/// </summary>
public global::System.Data.Objects.ObjectQuery<Audience> AudienceSet
Other that comments like this, there are NO comments!!
