Need help with ClickOnce deployment on .NET Framework 4.7.2 – "Unidentified program" warning
Hello, I have a WinForms application built on .NET Framework 4.7.2 that I'm publishing using ClickOnce from Visual Studio Community 2022 (official Microsoft version). Even after signing the application with a valid SHA256 V3 self-signed certificate, when I publish and try to install it via ClickOnce, I receive a warning saying the program is unidentified. Additionally, when I try to install the application on a machine that has antivirus software, the antivirus flags the program precisely because of the missing/certificate validation issue. How should I proceed? I'd like to know the correct way to publish with ClickOnce so that the application is fully recognized as valid by Windows, since I'm running into these antivirus validation problems. Thanks in advance for any guidance!
How to Resolve .NET Runtime Error 1026 after Windows 11 Update
I hope you're doing well. I am a teacher from Mexico and I'm facing a critical issue after a recent Windows 11 update to version 23H2. Ever since the update, I've been encountering a frustrating problem – a .NET Runtime Error 1026. This issue is causing applications to crash shortly after I launch them, making it impossible for me to access Mi Portal. Given that I heavily rely on Windows applications for my teaching tasks – from document editing to publications and printing, including crucial tasks like payslips handling – this situation has left me unable to perform my duties effectively. I understand that many educators are in a similar situation, where Windows OS and Office applications are our lifelines for seamless work. I urgently need a simple and effective solution to overcome this error and restore the functionality of my Windows 11 system. Your expertise and support in troubleshooting this .NET Runtime Error 1026 would be immensely appreciated. If anyone has encountered a similar issue or has successfully resolved it, I would be grateful for your insights. I need guidance or steps you can provide to help me swiftly resolve this issue and continue my teaching job without further disruptions. Warm regards and appreciation
.NET runtime issues - application not starting up
Hello, We have a .NET based application built using the .NET framework 8.0. The application runtimeconfig.json file shows this: MyApp.runtimeconfig.json "tfm": "net8.0", "frameworks": [ { "name": "Microsoft.NETCore.App", "version": "8.0.0" }, { "name": "Microsoft.WindowsDesktop.App", "version": "8.0.0" } ], Please note that we have Published the application and verified that only .NET version 8.0.16 components, DLLs etc are required. Anything higher than this does not show up. From the cmd prompt, the following runtimes are shown to be installed on the system: >dotnet --list-runtimes Microsoft.AspNetCore.App 8.0.21 [C:\Program Files\dotnet\shared\Microsoft.AspNetCore.App] Microsoft.NETCore.App 8.0.20 [C:\Program Files\dotnet\shared\Microsoft.NETCore.App] Microsoft.WindowsDesktop.App 8.0.20 [C:\Program Files\dotnet\shared\Microsoft.WindowsDesktop.App] However, when we try to start a Windows service which is installed as part of the application, it does not start up, and the Windows Event Viewer shows the following error: "Description: A .NET application failed. Application: MyAppControllerService.exe Path: C:\MyApp\MyAppControllerService.exe Message: You must install or update .NET to run this application. App: C:\MyApp\MyAppControllerService.exe Architecture: x64 Framework: 'Microsoft.NETCore.App', version '8.0.21' (x64) .NET location: C:\Program Files\dotnet\ The following frameworks were found: 8.0.20 at [C:\Program Files\dotnet\shared\Microsoft.NETCore.App] Learn more: https://aka.ms/dotnet/app-launch-failed To install missing framework, download: https://aka.ms/dotnet-core-applaunch?framework=Microsoft.NETCore.App&framework_version=8.0.21&arch=x64&rid=win-x64&os=win10" So, the issue is, even with Microsoft.WindowsDesktop.App 8.0.20 being installed on the system, it still asks for the .NET 8.0 Runtime (v8.0.21) to be installed. Please let me know why this is so? Since, as per this: https://learn.microsoft.com/en-us/dotnet/core/install/windows .NET Desktop Runtime includes the .NET runtime as well, and Microsoft.WindowsDesktop.App 8.0.20 is installed. Thanks in advance, JY
Duck Game Crashes
