我正在开发一个 UWP 应用程序,它使用了旧版 Windows 10 中不可用的一些功能。因此,我需要检查是否安装了创意者更新。
应用程序中有使用 AnalyticsInfo.VersionInfo 的版本检查代码。然而,最新一轮的 WACK 测试给出了以下失败:
FAILED Platform version launch • Error Found: The high OS version validation detected the following errors:
o Failed to stop the app AppName.group.mbb.
o The app Company.AppName_2.3.56045.0_x64__cx08jceyq9bcp failed platform version launch test.
• Impact if not fixed: The app should not use version information to provide functionality that is specific to the OS.
• How to fix: Please use recommended methods to check for available functionality in the OS. See the link below for more information. Operating System Version
我知道 this question , 但如果可能的话宁愿修复失败。 我在 MSDN 上找到了有关如何使 UWP 应用“版本自适应”的建议 here.
我现在有这段代码:
using Windows.Foundation.Metadata;
if (ApiInformation.IsMethodPresent("Windows.Networking.Connectivity.ConnectionProfile", "GetNetworkUsageAsync"))
{
//do stuff
}
我的Windows版本是1703 15063.483,代码其他地方使用GetNetworkUsageAsync成功。但是对 IsMethodPresent 的调用总是返回 false。
我的代码有什么问题?
是否有更好的功能来检查是否安装了 Creators Update?
更新: 对于上述失败,我遵循了 Microsoft 指南,并将版本检查从 AnalyticsInfo.VersionInfo 更改为 Windows.Foundation.Metadata.ApiInformation。该应用程序仍未通过 WACK 测试并出现相同的错误。
第二次更新:
将 Windows10 更新到 Creators Update,Build 16251.0 后,此错误在我的计算机上消失了。
最佳答案
也许像这样的辅助类?请注意,调用此方法的成本可能很高,因此建议执行一次并缓存数据。
(更新:如果您使用 Windows Composition API,您会发现 AreEffectsFast
and AreEffectsSupported
很有帮助,因为您可以使用它们根据用户的设备打开和关闭效果,操作系统条件。我扩展了下面的类以将它们公开为两个新属性。)
public class BuildInfo
{
private static BuildInfo _buildInfo;
private BuildInfo()
{
if (ApiInformation.IsApiContractPresent("Windows.Foundation.UniversalApiContract", 5))
{
Build = Build.FallCreators;
}
else if (ApiInformation.IsApiContractPresent("Windows.Foundation.UniversalApiContract", 4))
{
Build = Build.Creators;
}
else if (ApiInformation.IsApiContractPresent("Windows.Foundation.UniversalApiContract", 3))
{
Build = Build.Anniversary;
}
else if (ApiInformation.IsApiContractPresent("Windows.Foundation.UniversalApiContract", 2))
{
Build = Build.Threshold2;
}
else if (ApiInformation.IsApiContractPresent("Windows.Foundation.UniversalApiContract", 1))
{
Build = Build.Threshold1;
}
else
{
Build = Build.Unknown;
}
if (!BeforeCreatorsUpdate)
{
var capabilities = CompositionCapabilities.GetForCurrentView();
capabilities.Changed += (s, e) => UpdateCapabilities(capabilities);
UpdateCapabilities(capabilities);
}
void UpdateCapabilities(CompositionCapabilities capabilities)
{
AreEffectsSupported = capabilities.AreEffectsSupported();
AreEffectsFast = capabilities.AreEffectsFast();
}
}
public static Build Build { get; private set; }
public static bool AreEffectsFast { get; private set; }
public static bool AreEffectsSupported { get; private set; }
public static bool BeforeCreatorsUpdate => Build < Build.Creators;
public static BuildInfo RetrieveApiInfo() => _buildInfo ?? (_buildInfo = new BuildInfo());
}
public enum Build
{
Unknown = 0,
Threshold1 = 1507, // 10240
Threshold2 = 1511, // 10586
Anniversary = 1607, // 14393 Redstone 1
Creators = 1703, // 15063 Redstone 2
FallCreators = 1709 // 16299 Redstone 3
}
要初始化该类,请在 App.xaml.cs
中的 OnWindowCreated
之后立即调用它。
protected override void OnWindowCreated(WindowCreatedEventArgs args)
{
BuildInfo.RetrieveBuildInfo();
要使用它,只需调用
if (BuildInfo.Build == Build.Anniversary) { ... }
if (BuildInfo.BeforeCreatorsUpdate) { ... }
if (BuildInfo.AreEffectsFast) { ... }
