Configure registry permissions
Hi I have strange problem to set specific permission to a registry key. According to Microsoft's https://learn.microsoft.com/en-us/dotnet/api/system.security.accesscontrol.registrysecurity?view=net-10.0, it should work like this: private static RegistryKey CreateRegistryKey(RegistryKey parentPath) { RegistryKey childKey = parentPath.CreateSubKey("myKey"); RegistryAccessRule rule = new RegistryAccessRule( new SecurityIdentifier(WellKnownSidType.AuthenticatedUserSid, null), RegistryRights.ReadKey | RegistryRights.Delete, InheritanceFlags.ContainerInherit, PropagationFlags.None, AccessControlType.Allow); RegistrySecurity childACL = childKey.GetAccessControl(); childACL.AddAccessRule(rule); ShowSecurity(childACL); childKey.SetAccessControl(childACL); return childKey; } But if the code is executed in a windows service, I missing my permission!? How can this be? Am I doing something wrong? Have I overlooked something? 👁 Image8Views0likes0CommentsEntity Framework DB permissions
I want to use Entity Framework with a .Net 9 app but have had difficulty finding information on what DB permissions it needs in the app database. I've found a couple old StackOverflow posts but having created a user with the recommended db_datareader, db_datawriter and db_ddladmin and updated the app connection string to use it and now the app won't start. What more does it need?45Views0likes0CommentsPaytmgateway integration throwing exception error

Happy to be part of this community! 😊48Views2likes0CommentsBlazor parameter passed by reference
I got the impression that in Blazor parameters are always effectively passed by value which is why you need to use EventCallback for two-way binding to send a change in the parameter value back up to the component that passed it. But not so; reference types really are passed by reference. Therefore if a child component updates a parameter value that is a reference type then the value in the parent is changed and all you need to do is call `StateHasChanged` on the parent. Is this as intended? Have I misunderstood the documentation? Example: https://drive.google.com/file/d/1i1Rh36nHU1Z2voyHDtLVZ9GyziLw9AQq/view?usp=sharing (Don't seem to be able to attach here and it's not really feasible to inline a whole Blazor project.)130Views0likes2CommentsSharePoint List View Threshold Error while Fetching 5000+ Records in list.

Modern software systems are more complex than ever. Microservices talk to APIs. Background workers process queues. Frontend apps interact with authentication layers, caching services, and databases. In the middle of all this complexity, one thing becomes absolutely critical: clear visualization. With Visual Studio 2026, developers no longer need third-party plugins to visualize workflows and architecture. Visual Studio 2026 renders Mermaid charts directly in the editor — no extensions required. You can write Mermaid syntax yourself or let GitHub Copilot generate it for you. Flowcharts, sequence diagrams, and other visualizations render inline, keeping documentation inside your development workflow. This is more than just a convenience feature. It’s a shift in how developers document, collaborate, and communicate system design. https://dellenny.com/visualize-workflows-and-architecture-with-mermaid-charts-in-visual-studio-2026/446Views1like0CommentsGrant/Revoke permissions to Windows local certificates (certlm) in non-admin mode
I am working on granting/revoking permissions to windows local certificates (certlm) using Visual C++ 2022. The challenge is that this needs to be performed in non-admin privileges. We would need to remove "Everyone" permissions and grant read permissions for our NT Service account to windows local certificates (certlm). Is it possible to perform under non-admin privilege? It would be great help if can get solution for this.51Views0likes0CommentsHow 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.

I'm hoping the good folls of this community can help me figure out what's going on with a Windows Forms user control that I created and am trying to use. I created a user control that represents a single band of a parametric equalizer. In the designer, the control looks like this: When I debug the control in the Test Container, things look good: If we take a look at the actual PEQ application that will use the control, things still look OK in the designer: It's only when I fire up the application that things go... awry: What happened to all the TextBoxes? And the ComboBoxes? I''ve got a feeling that the fix for this is something really simple, and I'm going to feel like a complete idiot for not figuring out the obvious.

Hello, Today, all my Visual Studio 2019 Community projects stopped debugging and are displaying the following message in the browser: "This site can't be reached." I've tried using Visual Studio 2022 Community, but the problem is the same. I have numerous projects (Asp.Net - vb), and they all have the same issue. Even creating a new project (VS 20219 or VS 2022), the error persists. I've tried reinstalling IIS Express, disabling my antivirus, and reinstalling Visual Studio 2022 (since it was just for testing). Nothing works. Everything was working until yesterday, but now I can't work anymore. It seems like a Windows update, but I don't have restore points to revert to. I'd appreciate it if anyone has any idea what this could be. EduardoSolved337Views0likes2CommentsIt appears and error that does not exist

Hi Microsoft Tech Community, We have a Dataverse environment in our tenant, and I have its URL. I'm building a .NET application and need to connect it to Dataverse for data access. From the Learn docs, ChatGPT, and Copilot, it seems I need to use an App ID (Client ID) and Client Secret in the connection string (e.g., via Microsoft.PowerPlatform.Dataverse.Client). However, the Dataverse environment itself doesn't expose any App ID or Client Secret—where would I even find those if they exist? Here's the code snippet we found online that's using OAuth with AppId and RedirectUri, but we're unsure about the app registration part: using Microsoft.Crm.Sdk.Messages; using Microsoft.PowerPlatform.Dataverse.Client; using Microsoft.Xrm.Sdk; class Program { // TODO Enter your Dataverse environment's URL and logon info. static string url = "https://yourorg.crm.dynamics.com"; static string userName = "email address removed for privacy reasons"; static string password = "yourPassword"; // This service connection string uses the info provided above. // The AppId and RedirectUri are provided for sample code testing. static string connectionString = $@" AuthType = OAuth; Url = {url}; UserName = {userName}; Password = {password}; AppId = 51f81489-12ee-4a9e-aaae-a2591f45987d; RedirectUri = app://58145B91-0C36-4500-8554-080854F2AC97; LoginPrompt=Auto; RequireNewInstance = True"; static void Main() { //ServiceClient implements IOrganizationService interface IOrganizationService service = new ServiceClient(connectionString); var response = (WhoAmIResponse)service.Execute(new WhoAmIRequest()); Console.WriteLine($"User ID is {response.UserId}."); // Pause the console so it does not close. Console.WriteLine("Press the <Enter> key to exit."); Console.ReadLine(); } } Do I need to create a separate app registration in Microsoft Entra ID (Azure AD), link it to the Dataverse environment (perhaps as an application user?), and then use that app's Client ID/Secret in my .NET code? If so, could someone outline the exact steps, including permissions and Power Platform admin center setup? Any guidance or links to official walkthroughs would be greatly appreciated—thanks!102Views0likes0CommentsThe Evolution of Conversational AI in Microsoft’s Ecosystem
