Linq. Where versus On

[shapper]

Hello,

What is the difference between using:

from a in A
join b in B on a.Name equals b.Name
select a;

and:

from a in A
join b in B where a.Name equals b.Name
select a;

I was using "on" but on this group Jon suggested me the Where example.

Shouldn't I use the "on" in Joins and "where" when I want to impose
some condition to filter items on a condition?

Thanks,
Miguel

The first is valid, the second isn't.

Just a typo in a hastily written post, I'm afraid.

Yes.
