Question

I am trying to run a linq query using EF on .NET 3.5 and this query should return a result but isn’t. I am wondering if I don’t have it formatted correctly.

lret = IEnumerable<Place>
request.Category = long[]{1}

lret can have many categories

There is a place in the database that is assigned to CategoryId of 1

 lRet = lRet.Where(
    s => s.Categories.Any(
       t => request.Category.Contains(t.CategoryId)
    )
 );

Any help would be appreciated, thank you.

Answer 1

EF 1 doesn’t support IEnumerable<T>.Contains(). You need EF 4 for that.
