无法在发布模式下构建 UWP

Question

我有一个项目在调试模式下运行良好，但在发布模式下根本无法运行。

解决方案包含 3 个项目

• 共享项目

• windows phone 8.1 项目

• UWP 项目

这是错误输出

我使用的 nuget 包是

    "GoogleAnalyticsSDK": "1.2.12",
    "HockeySDK.UWP": "4.0.0",
    "HtmlAgilityPack": "1.4.9",
    "Microsoft.ApplicationInsights": "1.0.0",
    "Microsoft.ApplicationInsights.PersistenceChannel": "1.0.0",

    "MvvmLightLibs": "5.1.1",
    "Newtonsoft.Json": "8.0.3",
    "WriteableBitmapEx": "1.5.0"

更新

我尝试手动添加 Windows.Foundation.UniversalApiContract，但得到了这个

更新 2

在我取消选中 Compile with .Net Native 工具链功能后，它就起作用了。

有什么方法可以使用 .net 原生工具链来构建它？

Answer 1

我也遇到了一个非常相似的问题。我有一个类型，比如说 Foo，它引用了一个 winmd 类型 Windows.UI.Xaml.Visibility，见下文。

    public class Foo
    {
        public Windows.UI.Xaml.Visibility Visibility;
    }

当我尝试使用 XmlSerializer 序列化 Foo 类型的实例时，我在编译时遇到了完全相同的错误。似乎 .Net Native 工具在为 Foo 等类型生成 XmlSerializer 方面存在问题。

这是我的解决方法。我创建了自己的 Visibility 类型 MyVisibility，并将现有的 Visibility 字段更改为 get only 属性（这样 XmlSerializer 就不会序列化该属性）。

    public class Foo
    {
        public Windows.UI.Xaml.Visibility Visibility
        {
            get
            {
                return (Visibility)myVisibility;
            }
        }

        public MyVisibility myVisibility;
    }

    public enum MyVisibility
    {
        Visible = 0,
        Collapsed = 1
    }

这是我序列化 Foo 实例的测试代码，

    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);
        }
    }

希望这会有所帮助。
