Ravendb AsProjection（）为异步查询引发异常

在一个简单的测试场景中，可以使用以下设置：

public class TestObj
{
    public string Id { get; set; }
    public string Name { get; set; }
}

public class Summary
{
    public string MyId { get; set; }
    public string MyName { get; set; }
}

public class TestObjs_Summary : AbstractIndexCreationTask<TestObj, Summary>
{
    public TestObjs_Summary()
    {
        Map = docs => docs.Select(d => new { MyId = d.Id, MyName = d.Name });

        Store(x => x.MyId, FieldStorage.Yes);
        Store(x => x.MyName, FieldStorage.Yes);
    }
}

static IDocumentStore Setup()
{
    var store = new DocumentStore() { Url="http://localhost:8080" };
    store.Initialize();
    IndexCreation.CreateIndexes(MethodInfo.GetCurrentMethod().DeclaringType.Assembly, store);

    using (var session = store.OpenSession())
    {
        session.Store(new TestObj { Name = "Doc1" });
        session.Store(new TestObj { Name = "Doc2" });
        session.SaveChanges();
    }
    return store;
}

我怀疑这是一个bug，但作为一个RavenDB的新手，我首先想排除我把这里搞砸的可能性。有人知道为什么这个代码会失败吗

注意：这是在构建721和701上运行的，两者产生相同的结果

感谢您提供的任何帮助。

这看起来像个bug。我看不出你的代码有任何错误。我建议您在此处创建一个问题：

谢谢Daniel。记录问题

using (var session = store.OpenSession())
{
    var q = session.Query<Summary>("TestObjs/Summary").AsProjection<Summary>();
    Dump("Sync:", q.ToList());
}

using (var session = store.OpenAsyncSession())
{
    var q = session.Query<Summary>("TestObjs/Summary").AsProjection<Summary>();
    q.ToListAsync().ContinueWith(t => Dump("Async:", t.Result));
}

InnerException: System.InvalidCastException
Message=Unable to cast object of type 'TestObj' to type 'Summary'.
