That's (almost) equal to an INNER JOIN, so maybe:

 Select distinct t.* FROM table t inner join tableb b where t.id = b.id

If I recall correctly, you can use the Contains extension method. It should get converted to the appropriate SQL syntax.

e.g.

var inner = from Id in tableB
            select Id;

var outer = from t in table
            where inner.Contains(t.Id)
            select t;
