Question

I am having a simple table with 5 columns

id
id_user
col1
col2
col3

how can make Linq query to select an id_user and sum up all the col1, col2, col3 integers to make an average of those 3 columns ?

Thanks

Assuming you already have your table something along these lines should do it:

from row in table
let avgTotal = (new [] {row.col1, row.col2, row.col3}).Average()
select new {row.user_id, avgTotal}
