Can't build UWP in release mode - windows-10

Question

I have a project that is working well in debug mode, but not working at all in release mode.
The solution contains 3 projects
Shared project
windows phone 8.1 project
UWP project
here is the error output

Update
I tried to add the Windows.Foundation.UniversalApiContract manually, but got this
Update 2
After I have unchecked the Compile with .Net Native tool chain feature, it worked.
Any way to build it using the .net native tool chain ?

I also hit a very similar issue. I had a type, let's say Foo, referencing a winmd type Windows.UI.Xaml.Visibility, see below.
public class Foo
{
public Windows.UI.Xaml.Visibility Visibility;
}
I got the exact same error at compile time when I tried to serialize an instance of type Foo using XmlSerializer. It seems that .Net Native tools have problem with generating XmlSerializer for types like Foo.
Here's my workaround. I created my own Visibility type, MyVisibility, and changed the existing Visibility field to a get only property (so that XmlSerializer would not serialize the property).
public class Foo
{
public Windows.UI.Xaml.Visibility Visibility
{
get
{
return (Visibility)myVisibility;
}
}
public MyVisibility myVisibility;
}
public enum MyVisibility
{
Visible = 0,
Collapsed = 1
}
Here's my test code for serializing a Foo instance,
public static void Test()
{
var foo = new Foo();
foo.myVisibility = MyVisibility.Collapsed;
var serializer = new XmlSerializer(typeof(Foo));
using (var stream = new MemoryStream())
{
serializer.Serialize(stream, foo);
stream.Position = 0;
var foo1 = (Foo)serializer.Deserialize(stream);
Assert.True(foo.Visibility == foo1.Visibility);
}
}
Hope this helps.
