Group by in a list of objects

I have a list of objects like this:

BonusesToApprove = new List<Bonus>();

I need to group it by id. I've tried several approaches like the suggestion here but the compiler returns message: 

System.Collections.Generic.List<AdHoc.Objects.Bonus> does not contain a definition for 'GroupBy' ...

A sample of the code I've tried is:

var grouped = BonusesToApprove
    .GroupBy ...

Can anyone tell me what I'm doing wrong?

You may have forgotten to reference the LINQ namespace in your class.

Put this at the top with any other using statements you have:

using System.Linq;
