问题 I have a .NET standard library which is below: using System; using System.Diagnostics; using System.Runtime.InteropServices; namespace process_library { public class ProcessHandler { public ProcessHandler() { } [MTAThread] public Process[] GetProcesses() { return Process.GetProcesses(); } } } I then have a Template10 project with all the .net core stuff updated to the latest version (required to get it to build) and referenced my library. This all works so far. Inside my main view-model I

问题 Background: I'm having trouble getting my app's new version accepted by the Windows store. They say that it crashes on launch. The app runs fine even when installed from the appxbundle file on my computer. So I'm thinking maybe this has to do with the Desktop Extensions (for the UWP) that I've added. Perhaps I'm referencing the wrong version of that assembly. If the app is targeting version 16299 but min version is 14393 - which assembly of the desktop extensions should I include in the

问题 This is an extended question from here Using UWP monitor live audio and detect gun-fire/clap sound Thanks to Dernis I finally got the code working to monitor live audio and trigger events when decibel count is above a certain range. This works perfectly when we run it in office/closed/silent area. But when I take the app to open road, there will be traffic sound, wind sound, people talk sound and other noises and BLOW events are not identified correctly. I would like to implement something

问题 I am using BackgroundTransfer API for UWP and during my development I achieve much more than the limit (200) of transfer, until now this not become a problem because windows management cancel the transfers over the limit. But now, something occurs that I never can create a new download by BackgroundDownloader().CreateDownload() or call BackgroundDownloader.GetCurrentDownloadsAsync() because this exception always occur: WinRT information: Quota for maximum number of concurrent operations

问题 I am facing following error while publishing my UWP Xamarin based app on Windows Store. Package acceptance validation error: This package wasn't built for submission to the Microsoft Store. Make sure you're uploading a Release build with the .NET Native tool chain enabled. To remove "Windows Store" error, I have made following changes in my project After this it start another error as following while building project: 1: Error: NUTC1056:Internal Compiler Error: 0x8000ffff.

问题 I have a Xamarin Project where I generate a .pdf file from scratch and save it in my local storage. This works perfectly fine and can find it and open it in the disk where I saved it. However, I need to open the .pdf file immediately after creation programmatically. I already tried different variations using Process and ProcessStartInfo but these just throw errors like "System.ComponentModel.Win32Exception: 'The system cannot find the file specified'" and "'System

问题 Since a UWP app is a .NET Core app, a reference to a third party dll created in .NET 4.0 is not getting added in my UWP project in VS2017 . I'm getting the error shown below. A similar question has been answered here. But since that question is about 6 years old, and since then a lot has changed in the .NET Core world, I thought may be there are some better solutions to my problem than just rather complicated workarounds. Are there any simpler solutions to make a third party dll reference

问题 I created a UWP app with desktop extensions and added the startup task as mentioned here. (I set Executable="AutoStartupTest.exe" .) I logged off and logged on and got the error in the title, and don't know how to fix it because though it makes sense - why is it not in a container? This should happen automatically, no? The link is talking about a UWP app. EDIT The extension snippet as requested here. <Extensions> <desktop:Extension Category="windows.startupTask" Executable="AutoStartupTest

I see a lot of created files, including a CordovaApp.Windows10_1.0.0.43_x86.appx For iOS , the signing is handled via the xcode / developers console, and for Android I created using the keytool which is part of the JDK .
