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

Using an Azure ASP.NET MVC API from a Maui app, I am encountering the following error in the app when attempting to access the API. A few days ago, the initalization was working properly. The cloud app has been under further development, but the base api code has not been modified, only the response from the endpoints. The latest release NuGets are in use. What elements are being sought?

Bear with me please, I have not touched this stuff in a few years. Trying to upgrade Xamarin project to .Net Maui using CLI (latest version of VS 2022 cannot find the Upgrade assistant extension). I have downloaded the upgrade-assistant, but am not familiar with how to reply\how to make a selection of what is displayed after I enter "upgrade-assistant upgrade project-name" (it does not execute and instead displays information...see attached image). Is what is being display telling me that I need to ctrl-c out of this and re-enter the command using what they are showing? Please give me an example of using the Side-by-side upgrade. Is is also telling me that I need to do something with NuGet also on the command line? Thanks.

Hi I'm trying to modify the .NET runtime from github.com/dotnet/runtime. I created a copy of the Dictionary class called Dictionary2 in these source code files: C:\rt5\src\libraries\System.Collections\ref\System.Collections.cs C:\rt5\src\libraries\System.Private.CoreLib\src\System\Collections\Generic\Dictionary.cs When I use dot peek from Jetbrains, Dictionary2 exists in my System.Collections.dll, but when I import System.Collections.dll in my main console C# application, Dictionary2 gives me compiler errors. Am, I missing some code somewhere? Can you guys help me out here? Thanks!
