A strange run issue
I encountered a strange operational issue. After packaging my software in. msixbundle format, I installed and tested it locally. When clicking on the program icon in the start menu, an error occurred and a DLL could not be found. However, after confirmation, the main interface of the program can be opened. In fact, this DLL and the program's exe are in the same directory. But in the program files \ windows app \ myapp directory, clicking on this exe will allow the program to execute normally. My program is a. NET 8 winform program. How should I do?How to run a .NET Desktop Runtime app
So, Microsoft, this is an incredible piece of trolling and we all appreciate the laugh...but seriously, how do we run our program? Your "Download it now" button does nothing. Your "Download link" does nothing and is useless as text. As you can see in the screenshot, I have multiple versions installed and it still won't run. We tried this on multiple computers (a mix of Win 10 and Win 11) with the same results.Extract images from excel stored as Place in cell
Hello experts, I am trying to extract images from an Excel file using a C# program. My code successfully retrieves images that are placed over cells in the worksheet. Now, I need to adapt this functionality so that it can retrieve images which are stored as Place in cell in the excel .I want use this Azure Function for Business Central integration here is the code using Openize.Cells; using System.IO; using DocumentFormat.OpenXml; class Program { static void Main(string[] args) { string filePath = "C:\\Users\\Raj.Kamal\\Downloads\\test.xlsx"; // The path to your workbook string outputDirectory = "C:\\Users\\Raj.Kamal\\Downloads"; // Load the workbook from the specified file path Workbook wb = new Workbook(filePath); // Select the first worksheet from the workbook var worksheet = wb.Worksheets[0]; // Extract images from the worksheet var images = worksheet.ExtractImages(); // Check if the output directory exists; if not, create it if (!Directory.Exists(outputDirectory)) { Directory.CreateDirectory(outputDirectory); } // Loop through each extracted image foreach (var image in images) { // Construct a unique file path for the image using a GUID var outputFilePath = Path.Combine(outputDirectory, $"Image_{Guid.NewGuid()}.{image.Extension}"); // Save the image data to the constructed file path using (var fileStream = File.Create(outputFilePath)) { image.Data.CopyTo(fileStream); } } } } Any code snippets, documentation links, or best practices would be greatly appreciated. Excel file:Multi-project launch profiles not working
Hi, I am using Visual Studio 2022 (version 17.12.3) for an ASP.NET + React project. I want to take advantage of the new launch profiles feature to have multiples profiles for http and https, edge and chrome, etc. The feature is enabled, and I am able to create my profiles. So far so good. I have even ticked the share box so a .slnLaunch has been created. But when I am back to the main VS screen, I don't have the dropdown list in my toolbar to chose the profile to launch. I just have the old tooldbar : I tried to : Restart VS Restart my PC Disable/enable the feature with VS restarts in between Sorry for the screenshots in french btw ;) Thanks in advance !
Maui.NET and XCode validation
My application is developed on a Windows PC using Visual Studio 2022 (ver. 17.12.1) and .NET MAUI framework (ver. 9). After a successful build and testing using a virtual iPhone interface, Visual Studio connects remotely to the MacBook (Mac OS 15.1) sending the necessary project files to Xcode 16.1 targeting iOS version 18. The files are sent to Xcode successfully. However, Xcode validation fails with 4 errors. No matter what I change, the same errors persist. These validation errors are preventing me from deploying the code to TestFlight. Apple support refuses to help stating it is a problem with Visual Studio compilation of the package for Xcode. While I am not 100% confident, I suspect that the entries in the plist.info file contained within the project do not agree with where the files are physically located (even though they appear correct. However, I cannot see the key values in the plist file in the Xcode IPA package. I also notice that Maui opted to create entries in the plist.info file for “Assets.xcassets/AppIcon.appiconset”, but according to apple this is not how it should be done anymore. Could anyone provide thespecific changes in detail that need to happen to this project to have a successful XCode validation? I have been at this for two weeks with no solution in site. Below is a link to the referenced resources. Screenshots and Error documents Your help is greatly appreciated
Multiple ASP.NET Core Web API instances runs only once
I have an ASP.NET Core 8.0 Web API hosted on two IIS applications (app-1 and app-2) under the Default Web Site on a Windows 11 OS. Both IIS applications point to the same physical path (inetpub\wwwroot\myapp) and each application has its own dedicated application pool (app1andapp2). The application pools have unique identities (app1svcandapp2svc), both of which are members of the Administrators group. In the Web API, I have anAppEventsclass implementingIHostedService, withStartAsyncandStopAsyncmethods to handle application start and stop events. In theProgram.cs, I register it usingbuilder.Services.AddHostedService<AppEvents>(). When accessinghttp://localhost/app-1, theStartAsyncmethod is triggered as expected. However, when accessinghttp://localhost/app-2, theStartAsyncmethod does not execute. It seems that the application starts only once, despite both IIS apps pointing to the same physical directory. I've tried changing theAspNetHostingModelfromInProcesstoOutOfProcess, but the behavior remains the same. Is there a way to deploy multiple instances of the same web app, each running separately but pointing to the same physical directory, so that each instance correctly triggers its own StartAsync?
Enhancing Console.ReadLine to Accept a Message Parameter
n Python, the input function allows you to display a message and wait for user input in a single line of code. However, in C#, achieving the same functionality requires two lines: one for Console.WriteLine to display the message and another for Console.ReadLine to capture the input. Is it possible to have a ReadLine function in C# that takes a message as a parameter and waits for user input?
Automation testing for ToastNotifications
I am testing a WPF application, and I want to access a button on a Toast Notification. I am using the Microsoft UI Automation framework, but cannot locate the Notification window in the RawView tree or from the RootElement (.Find*). However tools like Inspect do find the Notification window. => what is the issue here? I could use NotificationListener, but that doesn't give access to any button. Correct me if I'm wrong. So how can I access those Toast Notifications with MS UI Automation?

Hi! I'm trying to write tests for a small minimal API based on asp.net core. I don't want to test over the internet, but start the app within the tests and call the endpoints on the running site. Is this possible? And how? Should I use TestServer for this? I'm new to writing tests, so maybe it's an easy issue to code. Thanks! :)How can I find CPE of dll in .NET?

How to increase session timeout
Hello Everyone, I am working on .NET framework 4.8 with a MVC web application. To login I am using MFA with microsoft's openid-configuration method. When I create FormsAuthenticationTicket and try to set session timeout as per my requirement but it doesn't work. See the sample code as below FormsAuthenticationTicket ticket1 = new FormsAuthenticationTicket( 1, // version adminEmail, // get username from the form DateTime.Now, // issue time is now DateTime.Now.AddDays(365), true, // cookie is not persistent "XXXXX" // role assignment is stored in userData ); But it is not working properly, it gets timeout within 15 minsQuestion about Kubernetes Deployment tutorial on Microsoft Learn
I am going through the tutorial Module on Microsoft Learn titled "Deploy a .NET Microservice to Kubernetes" and am on the third unit located here: https://learn.microsoft.com/en-us/training/modules/dotnet-deploy-microservices-kubernetes/3-exercise-push-to-docker-hub. I am stuck under the "Verify the Docker images by creating containers in the codespace" heading on the fourth step. It tells you to select the port for the front end and open the service in a browser. However, there were no ports here that the step seemed to suggest were already there and I had to set it up. Given that the port for the frontend service of this tutorial is 32000:8080 according to the docker-compose.yml file for this tutorial project, is this what I should put in the ports tab? If so, the service does not display in my browser when I click on the globe icon as instructed by the tutorial and all I see is an HTTP 502 message. What should I do so that I can view the service? The repository for this tutorial service is located at https://github.com/MicrosoftDocs/mslearn-dotnet-cloudnative in the dotnet-kubernetes folder and I have attached images as well of the discussed configuration and error message below:
