问题 The Windows.Security.Cryptography.CryptographicBuffer class contains static methods for converting between strings and an IBuffer-implementing object which can be used by the cryptography functions. Do these objects have special security measures internally, such as preventing paging to disk, encrypting at rest, and/or erasing when the object is freed? If not, is there an alternative? For the alternatives, C#/.Net for Windows Universal Apps is preferred; C++/CX if necessary. EDIT: Asking the

问题 I'm testing my Win32 app converted to UWP, so I'm new to the whole Windows 10 Store concept. So far I was able to get my app certified & published in the store via a private link.

问题 I have searched everywhere but can not find an answer how could I load a 3d model (.obj/.fbx...) into UWP. I tried it with Helix, but it doesn't work well on the UWP yet. I would like to rotate this model after its loaded. 回答1: You need to use <SwapChainPanel /> Here is the MSDN documentation on it Here is a tutorial on how to use it. The tutorial is for Windows 8 but there are comments from people using this in UWP. All of this was found (On Bing) in one search. This was the StackOverflow

问题 I have all icon assets sorted out for a UWP app as detailed here except for the icon on the Taskbar. This is because I find the description at the link referred to somewhat long-winded and confusing as to how I should name an icon that should show up on the Taskbar (when the app is running). I have icon sizes prepared in dimensions of 16x16, 24x24, 32x32, 48x48, 256x256. I named them as recommended as MyAppName AppList.targetsize-XX.png where XX is 16, 24, 32, 48 or 256. As I've indicated

问题 I updated one UWP App to a newer SDK and set target version to 16299 and Min Version to 15063. Then I'm using the Windows.Foundation.UniversalApiContract Namespace to use features of the new SDK if available. Example: xmlns:contract5NotPresent="http://schemas.microsoft.com/winfx/2006/xaml/presentation?IsApiContractNotPresent(Windows.Foundation.UniversalApiContract,5)" xmlns:contract5Present="http://schemas.microsoft.com/winfx/2006/xaml/presentation?IsApiContractPresent(Windows.Foundation

问题 How can I close the current active Page in UWP development? I want to start a new Page and close the current one, so the user cannot go back to that page. Is there any method in UWP similar to Android's method "finish()"? 回答1: I think you should be able to do this by removing last page from back stack after navigating to a new one. Sample code in OnNavigatedTo of a new page: protected override void OnNavigatedTo(NavigationEventArgs e) { base.OnNavigatedTo(e); this.Frame.BackStack.RemoveAt
