Question

how can I simulate the following sql query using linq

Select * From Resource Where Id in
(
Select ResourceId From ResourceRelCategory Where CategoryId =8

You could try something like:

var result = from r in Resource
             where (
                 select c from ResourceRelCategory
                 where c.CategoryId==8
                 select c.ResourceId
             ).Contains(r.Id)
             select r;

or

var result = from r in Resource
             where r.Categories.Any(c => c.Id == 8)
             select r;

or maybee the other way around:

Category.First(c => c.Id == 8).Resources
