I have a Linq provider that sucessfully goes and gets data from my chosen datasource, but what I would like to do now that I have my filtered resultset, is allow Linq to Objects

    Unless I'm misunderstanding, I generally just add .ToArray() in the chain of linq methods at the point where I want the linq provider to execute.

    For example (think Linq to SQL)

    var result = datacontext.Table
       .Where(x => x.Prop == val)
       .OrderBy(x => x.Prop2)
       .ToArray()
       .Select(x => new {CoolProperty = x.Prop, OtherProperty = x.Prop2});
    

    So through OrderBy() gets translated into SQL, but the Select() is LINQ to Objects.
