NodaTime TypeInitializationException仅限设备，仅限发布

我使用NodaTime得到一个TypeInitializationException，但仅在Release中，并且仅在设备上。

这是堆栈跟踪：

System.TypeInitializationException: The type initializer for 'Patterns' threw an exception. ---> System.TypeInitializationException: The type initializer for 'NodaTime.Text.ZonedDateTimePattern' threw an exception. ---> System.TypeInitializationException: The type initializer for 'NodaTime.DateTimeZone' threw an exception. ---> System.TypeInitializationException: The type initializer for 'NodaTime.Text.OffsetPattern' threw an exception. ---> System.Resources.MissingManifestResourceException: Exception of type 'System.Resources.MissingManifestResourceException' was thrown.

Phil Hoff的解决方法为我们解决了这个问题。创建以下WindowsRuntimeResourceManager类：

/// <summary>
/// from http://blogs.msdn.com/b/philliphoff/archive/2014/11/19/missingmanifestresourceexception-when-using-portable-class-libraries-in-winrt.aspx
/// </summary>
public class WindowsRuntimeResourceManager : ResourceManager
{
    private readonly ResourceLoader _resourceLoader;
    private WindowsRuntimeResourceManager(string baseName, Assembly assembly)
        : base(baseName, assembly)
    {
        _resourceLoader = ResourceLoader.GetForViewIndependentUse(baseName);
    }
    public static void InjectIntoResxGeneratedApplicationResourcesClass(Type resxGeneratedApplicationResourcesClass)
    {
        resxGeneratedApplicationResourcesClass.GetRuntimeFields()
          .First(m => m.Name == "resourceMan")
          .SetValue(null, new WindowsRuntimeResourceManager(resxGeneratedApplicationResourcesClass.FullName, resxGeneratedApplicationResourcesClass.GetTypeInfo().Assembly));
    }
    public override string GetString(string name, CultureInfo culture)
    {
        return _resourceLoader.GetString(name);
    }
}

在使用NodaTime（例如，在应用程序构造函数中）之前，请更换NodaTime程序集的资源管理器：

        Assembly nodaTimeAssembly = typeof(LocalDate).GetTypeInfo().Assembly;
        Type messagesResource = nodaTimeAssembly.GetType("NodaTime.Properties.Messages");
        Type patternResource = nodaTimeAssembly.GetType("NodaTime.Properties.PatternResources");
        WindowsRuntimeResourceManager.InjectIntoResxGeneratedApplicationResourcesClass(messagesResource);
        WindowsRuntimeResourceManager.InjectIntoResxGeneratedApplicationResourcesClass(patternResource);
