Just my opinion...

Uh…  No.  I get this rhetorical question from fellow developers a lot.  LINQ uses the “from-where-select” syntax (with the “from” and the “select” in a more sensible order) from SQL but that’s only to give developers a familiar model.

LINQ can be used to query relational data sources like, SQL Server, Oracle, MySql, etc.  LINQ can also be used to solve general programming problems in a functional way.

Go take a quick look here for a rather contrived puzzle example.  If you still think LINQ was made just to query relational data after looking at it…  I’m not sure how to make it clearer for you.

On the turning away
From the pale and downtrodden
And the words they say
Which we won’t understand
Don’t accept that what’s happening
Is just a case of others’ suffering
Or you’ll find that you’re joining in
The turning away

It’s a sin that somehow
Light is changing to shadow
And casting its shroud
Over all we have known
Unaware how the ranks have grown
Driven on by a heart of stone
We could find that we’re all alone
In the dream of the proud

On the wings of the night
As the daytime is slurring
Where the speechless unite
In a silent accord
Using words you will find are strange
And mesmerized as they light the flame
Feel the new wind of change
On the wings of the night

No more turning away
From the weak and the weary
No more turning away
From the coldness inside
Just a world that we all must share
It’s not enough just to stand and stare
Is it only a dream that there’ll be
No more turning away?

“On The Turning Away”
Pink Floyd

My conservative friends actually look upon me with derision for thinking and feeling any of the emotion evoked by this song.  You know…  Being a bleeding-heart liberal and all.
