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
I am hoping that someone here might be able to steer me in the right direction. I have posted in the game's forum, but I am not receiving any support there. I have a new laptop running Windows 11. We are getting frequent game crashes while playing Duck Game. I am wondering if it is a compatibility issue as the game is older. Any help would be GREATLY appreciated.

Now DB works on MariaDB 11, the old db was on MariaDB 8 What can I verify?Can't able to Upload Images on Azure Server if it is more than 128KB
Hi Everyone , I am trying to upload image and store but when i do it in my local server its working fine but when i push the same code in server i am getting entity too large I reached out microsoft support they are telling that "The content type format is supposed to be image as example given to upload the image file otherwise the application gateway will not understand the image and tries to accept only 128KB which is why the request is not accepted with Application Gateway. " when i am debugging i am getting same content type = image/jpeg . Code snippet for storing private void SaveImage(int vendItemID) { try { string folderPath = @"C:\UploadedImages\"; Directory.CreateDirectory(folderPath); string fileExtension = Path.GetExtension(fileUpload.FileName).ToLower(); string fileName = Path.GetFileNameWithoutExtension(fileUpload.FileName); string newImageName = string.Empty; dbCon.Server = "***"; dbCon.OpenConnection(); // Optimize and compress the image byte[] optimizedImageBytes = CompressImageToTargetSize(fileUpload.PostedFile.InputStream, fileExtension); // Convert to Base64 string base64String = Convert.ToBase64String(optimizedImageBytes); using (SqlCommand cmd = new SqlCommand("***", dbCon.Cnn)) { cmd.CommandType = CommandType.StoredProcedure; AddImageParameters(cmd, vendItemID, fileName, fileExtension); cmd.Parameters.AddWithValue("@ImageBase64", base64String); var outputCodeParam = new SqlParameter("@ImageNewName", SqlDbType.NVarChar, 200) { Direction = ParameterDirection.Output }; cmd.Parameters.Add(outputCodeParam); cmd.ExecuteNonQuery(); newImageName = outputCodeParam.Value.ToString(); } string newFilePath = Path.Combine(folderPath, newImageName); File.WriteAllBytes(newFilePath, optimizedImageBytes); UpdateImagePath(newImageName, newFilePath); } catch (Exception ex) { ShowMessage("Error while saving image: " + ex.Message, Color.Red); LogError("Image save failed", ex); throw; } finally { dbCon.CloseConnection(); } } I also try to compress and change it to base 64 but its not working. Kindly assist on what steps i need to take. Thanks, Shahid Note :WebForm i m working on .Connection between .NET and AUTOCAD ELECTRICAL

How to load accoremgd.dll properly so that this application can use autocad accoremgd functions properly.
.Net 8 Isolated upgrade issue- RPC Exceptions in .Net Core Function App
Hi Team, Need Immediate help. I am continuously receiving RPC Exceptions when I have upgraded my Function App to .Net 8 previously I had zero exceptions related to this in .Net 6. Scenario: We are creating builder with ConfigureFunctionsWebApplication() like below: 1. var builder = FunctionsApplication.CreateBuilder(args); 2. builder.ConfigureFunctionsWebApplication(); And basically, we have Http triggers and SB triggers in the application and only couple of them are facing issue and the error in AI states that this is an issue related to worker. I have copied multiple exception wrapped as an RPC exception below: 1. An exception was thrown by the invocation. Exception: System.TimeoutException: Timed out waiting for the function start call. 2. The operation has timed out at Microsoft.Azure.Functions.Worker.Extensions.Http.AspNetCore.DefaultHttpCoordinator.SetFunctionContextAsync(String invocationId, FunctionContext context) 3.Microsoft.Azure.Functions.Worker.Extensions.Http.AspNetCore.DefaultHttpCoordinator.SetFunctionContextAsync(String invocationId, FunctionContext context) 4.
