Windows Server 2019 Cannot Install .NET 3.5
I am running Windows Server 2019 (Version 1809, Build 17763.4499) and I cannot install .NET Framework 3.5. Below is the current installation status of the feature on my machine: PS > Get-WindowsFeature -Name NET-Framework-Features,NET-Framework-Core,NET-HTTP-Activation,NET-Non-HTTP-Activ Display Name Name Install State ------------ ---- ------------- [X] .NET Framework 3.5 Features NET-Framework-Features Installed [ ] .NET Framework 3.5 (includes .NET 2.0 and 3.0) NET-Framework-Core Removed [ ] HTTP Activation NET-HTTP-Activation Removed [ ] Non-HTTP Activation NET-Non-HTTP-Activ Removed Through hours of searching online I have not been able to discover a resolution to the issue I am seeing. I followed the installation steps in https://woshub.com/how-to-install-net-framework-3-5-on-windows/ as this was the most complete guide. None of the suggested installation methods worked. Via Server Manager: Add roles and features -> Features -> .NET Framework 3.5 Features -> .NET Framework 3.5 (includes .NET 2.0 and 3.0 ); Using DISM: DISM /Online /Enable-Feature /FeatureName:NetFx3 /All Using DISM: DISM /Online /Enable-Feature /FeatureName:NetFx3 /All /Source:D:\sources\sxs /LimitAccess With PowerShell: Install-WindowsFeature -Name NET-Framework-Core With PowerShell: Install-WindowsFeature -Name NET-Framework-Core -Source D:\Sources\SxS With DISM: DISM /online /Add-Package /PackagePath:D:\Sources\SxS\microsoft-windows-netfx3-ondemand-package~31bf3856ad364e35~amd64~~.cab I also tried using the offline packages from my installation media without success. And when trying to use GPO to force installation from / prohibit installation from Windows Update (non-WSUS) I did not see any results. Regardless which method I use, I end up getting the same 0x800f0800 error. I've only come across https://social.technet.microsoft.com/Forums/windowsserver/en-US/5be0b03c-f499-4530-837d-76eacb4f1473/net-framework-35-cannot-install when trying to install a Windows feature, but their resolution was just rebuilding their server. This is not a viable option for my scenario. The full error from PowerShell is displayed below: PS> Install-WindowsFeature -Name NET-Framework-Core -Source D:\Sources\SxS Install-WindowsFeature : The request to add or remove features on the specified server failed.

How to add a timer to C# Service
Hi everyone I am new to coding in c # and trying to write a windows service in c #, my service seems to be working fine except for one thing: I try to make it run in a loop, say every 30 seconds, another program. But for the moment when I launch my service, it executes the program only once. My code: using System; using System.Runtime.InteropServices; using System.Diagnostics; // SET STATUS using System.ComponentModel;// SET STATUS using System.ServiceProcess; using System.Timers; //using System.ServiceProccess;// SET STATUS public enum ServiceType : int { // SET STATUS [ SERVICE_WIN32_OWN_PROCESS = 0x00000010, SERVICE_WIN32_SHARE_PROCESS = 0x00000020, }; // SET STATUS ] public enum ServiceState : int { // SET STATUS [ SERVICE_STOPPED = 0x00000001, SERVICE_START_PENDING = 0x00000002, SERVICE_STOP_PENDING = 0x00000003, SERVICE_RUNNING = 0x00000004, SERVICE_CONTINUE_PENDING = 0x00000005, SERVICE_PAUSE_PENDING = 0x00000006, SERVICE_PAUSED = 0x00000007, }; // SET STATUS ] [StructLayout(LayoutKind.Sequential)] // SET STATUS [ public struct ServiceStatus { public ServiceType dwServiceType; public ServiceState dwCurrentState; public int dwControlsAccepted; public int dwWin32ExitCode; public int dwServiceSpecificExitCode; public int dwCheckPoint; public int dwWaitHint; }; // SET STATUS ] public enum Win32Error : int { // WIN32 errors that we may need to use NO_ERROR = 0, ERROR_APP_INIT_FAILURE = 575, ERROR_FATAL_APP_EXIT = 713, ERROR_SERVICE_NOT_ACTIVE = 1062, ERROR_EXCEPTION_IN_SERVICE = 1064, ERROR_SERVICE_SPECIFIC_ERROR = 1066, ERROR_PROCESS_ABORTED = 1067, }; public class Service_PSTest : ServiceBase { // PSTest may begin with a digit; The class name must begin with a letter private System.Diagnostics.EventLog eventLog; // EVENT LOG private ServiceStatus serviceStatus; // SET STATUS public Service_PSTest() { ServiceName = "Test2"; CanStop = true; CanPauseAndContinue = false; AutoLog = true; eventLog = new System.Diagnostics.EventLog(); // EVENT LOG [ if (!System.Diagnostics.EventLog.SourceExists(ServiceName)) { System.Diagnostics.EventLog.CreateEventSource(ServiceName, "Application"); } eventLog.Source = ServiceName; eventLog.Log = "Application"; // EVENT LOG ] EventLog.WriteEntry(ServiceName, "Test2.exe Test2()"); // EVENT LOG } [DllImport("advapi32.dll", SetLastError = true)] // SET STATUS private static extern bool SetServiceStatus(IntPtr handle, ref ServiceStatus serviceStatus); protected override void OnStart(string[] args) { EventLog.WriteEntry(ServiceName, "Test2.exe OnStart() // Entry.

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
Error -another entity of the same type already has the same primary key value
Good afternoon, I have an error, and I think you can help me. Error in Microsoft Visual Studio (Microsoft .NET Framework Version 4.8, EntityFramework 6.2): " System.InvalidOperationException HResult=0x80131509 Message=Attaching an entity of type 'SGI2DataAccess.Models.ProjectForecast' failed because another entity of the same type already has the same primary key value.

This may be because some entities are new and have not yet received database-generated key values.

.Net 4.8 not showing in "Windows Features" for Windows Server 2019
Hello, We have installed .Net 4.8 on a Windows Server 2019 OS, and it wont show under "Windows Feautures". What we see there is only .Net 3.5 and .Net 4.7. It´s crucial that we see .Net 4.8 in "Windows features" so we can turn on/off some features needed for us in order to run our programs that we use. Reading this thread with the same issue: https://techcommunity.microsoft.com/t5/windows-server-for-it-pro/server-2019-net-4-8-not-showing-in-features/m-p/3714980 One comment told OP that its included in Windows, but it wasnt included in our windows. And even if it was, we still need to see the .Net 4.8 so we can turn on and off some features. What can we do?
The SSL connection could not be established
We have developed an application using Microsoft.Net Core. The application has a function that generates tokens and executes an API call. Suddenly the application is throwing an error while generating the token. When we test the application, the same application is working on Windows applications but not on Windows servers.

VB.NET. "The process cannot access the file because it is being used by another process"
I should add a list of files into a ZIP. Procedure code is like this Sub CreateZip Dim FileList As New ArrayList 'List of File Paths to be added to the ZIP For Each path in FileList Try AddFileToZip(ZipFilePath, path.ToString) Catch (ex as New Exception) .... End Try Next End Sub And this is AddFileToZip Public Sub AddFileToZip(ByVal zipFilename As String, ByVal fileToAdd As String) Using zip As Package = System.IO.Packaging.Package.Open(zipFilename, FileMode.OpenOrCreate) Dim destFilename As String = ".\" & Path.GetFileName(fileToAdd) Dim uri As Uri = PackUriHelper.CreatePartUri(New Uri(destFilename, UriKind.Relative)) If zip.PartExists(uri) Then zip.DeletePart(uri) End If Dim part As PackagePart = zip.CreatePart(uri, "", CompressionOption.Normal) Using fileStream As New FileStream(fileToAdd, FileMode.Open, FileAccess.Read) Using dest As Stream = part.GetStream() CopyStream(fileStream, dest) End Using End Using End Using End Sub At runtime, I get this error message The process cannot access the file [ZipFilePath] because it is being used by another process this error is raised randomly, maybe on adding small files into the Zip. If I place breakpoints and run procedure in debug mode, it works. It seems clear that procedure thread is not synchronized with IO, so that my procedure loop continues even if IO is still adding processed file into Zip (ie VB.NET is faster than IO). I also tried to place a Thread.Sleep(1000) before AddFileToZip, but this may be not enough to synchronize the two processes. Placing Thread.Sleep(2000) seems to make procedure work, but it may slow down dramaticly performances (I should pack more than 50 files into my Zip). So, how can I force my loop to "wait" until IO Process has released ZIP file?
My Program crashes suddenly every day with a Kernelbase Error
Hi, My program without any change started to crash. This has happened to 3 servers, and they all have the BitDefender antivirus. I have added the folder path of my execution in the exclusion list to all 3, and on the 2 servers the problem seems to be fixed. On the 3rd one, it keeps crashing. How can I fix the problem? The program has not changed the last 6 months and started happening on all 3 servers around the same time.
