Sergey Stronchinskiy updated IGNITE-19260:
------------------------------------------
Description:
Support nested member init projections:
{code:c#}
[Test]
public void TestSelectMemberInitSupportsFields1()
{
var res = PocoView.AsQueryable()
.Where(x => x.Key == 2)
.Select(x => new MyClass1
{
Key = x.Key,
Class2Prop = new MyClass2
{
Value = x.Val
}
})
.ToArray();
Assert.AreEqual(1, res.Length);
var resRow = res[0];
}
private class MyClass1
{
public long Key { get; set; }
public MyClass2 Class2Prop { get; set; } = null!;
}
private class MyClass2
{
public string? Value { get; set; }
}
{code}
Also check possibility to combine with anonymous types.
