EntityDataSource, ObjectDataSource, and LinqDataSource - For what and how to use them

Hi:

We're creating web applications using Visual Studio 2010 and Visual Basic.

We saw in the list of data sources offered by VS 2010: EntityDataSource, ObjectDataSource, and LinqDataSource beside AccessDataSource (used with Access db) and SqlDataSource (used with SQL server db)

Would you help to explain for what applications these datasources are used and examples of how to use them?

Thanks a lot,

Somits

I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

ObjectDataSource, as the name suggests is used with collections/lists of objects. For example, a list of customers. LINQDataSource is similar but it works with LINQed collections of objects such as iqueryable and ienumerable etc. EntityDatasource is used with EntityFramework which is a different data access technology.
