Macos dotnet wacth https not working.
Hello; I wanted to start Asp.net core Angular training. I am a Macos M1 user. I installed the necessary plugins with Vscode and created a webapi. But the api does not work with the dotnet watch command. It says the reason is https certificate problem. launchSettings.json : { "$schema": "http://json.schemastore.org/launchsettings.json", "profiles": { "http": { "commandName": "Project", "dotnetRunMessages": true, "launchBrowser": false, "applicationUrl": "http://localhost:5000;https://localhost:5001", "environmentVariables": { "ASPNETCORE_ENVIRONMENT": "Development" } } } } applicationUrl also only works when it is http. In the error command: Microsoft.Extensions.Hosting.Internal.Host[11] Hosting failed to start System.InvalidOperationException: Unable to configure HTTPS endpoint. No server certificate was specified, and the default developer certificate could not be found or is out of date. To generate a developer certificate run 'dotnet dev-certs https'. To trust the certificate (Windows and macOS only) run 'dotnet dev-certs https --trust'. There is a long error like this. I enter the following commands in the terminal, in order: 1- dotnet dev-certs https 2- dotnet dev-certs https --trust I approve the certificate. When I say 3-dotnet dev-certs https --check, I get the error: No valid certificate found. I found the localhost certificates in Keychain Access and selected the always trust option. But I couldn't find a solution. Also: dotnet dev-certs https --trust Trusting the HTTPS development certificate was requested. If the certificate is not already trusted we will run the following command: 'security add-trusted-cert -p basic -p ssl -k <<login-keychain>> <<certificate>>' This command might prompt you for your password to install the certificate on the keychain. There is an addition process like To undo these changes: 'security remove-trusted-cert <<certificate>>' I didn't know how to do it. Can you help me with this?
.NET Web API CancellationToken don't work with Angular .unsuscribe()?
In Angular, I make API calls by subscribing to observables. When a user cancels a request, the application unsubscribes to the subscription which cancels the request (I can see this in the network tab of the Chrome browser). However, it does not trigger the endpoint and so the cancellation token param in our endpoint is of no use. Is there a way around this? I need the cancellation token to cancel all database request.
Latest ASP.Net
Hello All, I've been working on a web application developed in ASP.Net and .Net Framework 4 for a few years. Trying to find out the new technologies that replaced asp.net web forms to brush up the skill set, found that ASP.Net Core is the new one. I've worked on ASP.Net MVC framework. Does this core completely replaced asp.net? Can the web forms applications be created in core? What is the latest framework to develop web apps? Thanks
Best design software for personal project
I'm starting to develop a WPF software, with some components like Ribbon Menu and Docking Layouts,but I find an intuitive design, better organized and cleaner, an interface that does not seem to be WinForms. Does anyone know of any components or frameworks that can do this type of design? My cordial greetings.

Hi, I am at the beginning of starting my own project. I come from a database tech background and have not kept up to date with all the Web frameworks. The project will run on azure and I will use visual studio. I need to be able to access opensteet maps for mapping and coordinates. So what I need to do is go to open street maps. Click somewhere on the map and a special tag should come up which I am populating in c# based on coordinates and country. I will to do the same on android, ios. Is xanarin my best option here? So there is MVC, the new .net core, web forms, some other framework. I didn't particularly like the .net core as there seems to be no designer with toolbox and components. Or do I use umbraco framework. I also saw a project called OSMsharp on github. What .net tech should I go for asI have to use openstreetmap and no Google maps, am i limited by this?. Thank you! Panos

What do i use to make a inline editable table for razor page?
Datatable.net edit function costs money, so I'm trying to make my own table with inline editing with Razor page, but I don't know what is the modern way to do it. Razor is not so modern but I don't think I want to use jQuery for it if there's a better way. I read some posts and there are a lot of answers like Ajax, jQuery, fetch API,... and I also found a library called Hydro for Razor that mimics SPA functionality, but I don't know if it's applicable to this task. Can someone point me in a direction?
