FetchStrategy with anonymous result type

[Dmitry]

Hi, Telerik.

I'm using FetchStrategy for getting Collection navigation field values by one query. Eeverything work with code:

class Program
{
    static void Main(string[] args)
    {
        var fetchStrategy = new FetchStrategy();
        fetchStrategy.LoadWith<Book>(b => b.Cities);
        using (var ctx = new FluentModel())
        {
            ctx.FetchStrategy = fetchStrategy;
            var books = ctx.Books.Select(b => new { b.Cities }).ToList();
        }
    }
}

But if I add to anonymous type field of Books FetchStrategy doesn't work. For Example added b.Name

...
            using (var ctx = new FluentModel())
            {
                ctx.FetchStrategy = fetchStrategy;
                var books = ctx.Books.Select(b => new {b.Name, b.Cities}).ToList();
            }
...

What must I do for working FetchStrategy fine in last example?

Thank you.

Hello Dmitry,

This is the expected behavior of Telerik Data Access - any fetch strategies would not be applied when using projection into anonymous or not persistent types. Additionally, it would prevent Telerik Data Access from utilizing its caching system. For these reasons I would recommend you to not to use projections unless you absolutely need to.

Should you have any more question do not hesitate to contact us again.
