After installing the WebView2 components for UWP and creating a project using these instructions, the web view cannot load a local IP Source="http://10.20.30.59/".

• The same URL works in WPF WebView, however I need to migrate because of other issues.
• The same URL works in other browsers, just not in WebView2. "Normal" URLs like https://bing.com work fine in the WebView2.
• Turning the firewall off still doesn't allow the content to load.
• Turning off the Windows antivirus under Virus & threat protection settings does not help.
• The CoreWebView2NavigationCompletedEventArgs.IsSuccess value is false and WebErrorStatus is ConnectionAborted.
• Under DevTools > Network > Headers, the failed page has the value Referrer Policy: strict-origin-when-cross-origin. A visit to https://developer.chrome.com/blog/referrer-policy-new-chrome-default/ shows that this can be modified with Chrome flags, but I don't know how to run those flags to verify this is not the problem.
• The feedback area has some similar issues like https://github.com/MicrosoftEdge/WebView2Feedback/issues/2145, but not one that shows how to debug it.
• In the Package.appxmanifest, adding Internet (Client & Server), Internet (Client), Private Networks (Client & Server), and Remote System capabilities does not help.
• Using Node JS + Node Package Manager to run a local server works on Source="http://10.20.30.106:8080/". This leads me to believe the problem is with the source itself. https://devpractical.com/host-a-html-page-on-localhost/#nodejs-section
• The UWP sample WebView2Samples-master\SampleApps\webview2_sample_uwp from https://github.com/MicrosoftEdge/WebView2Samples works fine using the problematic address. Why?

Below is the minimal reproducible example from the instructions:

I need to install older version of rails - 5.2.2 on Windows 10. I'm new to bash, so I went into this task blind, but I managed to install Ruby 2.5.0p0(which I also need). Now I've been stuck for few hours trying to figure out how to install rails. After running: $ gem install rails -v 5.2.2 I'm met with following error message:

I tried to setup SDL 2 in visual studio following similar instruction to tutorial and the result was that visual studio was recognizing SDL.h but it was not recognizing SDL2/SDL.h and the include folder of sld2 development tools (link) does not have any SDL2/SDL.h file. How to setup SDL2/SDL.h in visual studio ?

Brand new install of centos 9. (mostly minimal)

nothing works, any ideas?

I'm getting an error where I can't install XCode because my MacOS version is 10.15 when the requirement is version 11 or higher.

I don't want to upgrade my mac version because this is a company laptop so my other development tools might get affected.

How do I create a workaround for this?

I am working on login functionality in my project, now, flow looks like this (from front-end to back-end):

I'm trying to automate a process using PowerPoint from C#, to do this I want to open (or create a new) PowerPoint presentation, add a slide, and save the document.

I've got the entire office 2019 package installed on my machine and can access the ppt api by referencing the Interop.Microsoft.Office.Interop.PowerPoint (from the Microsoft PowerPoint 16.0 Object Library reference) along with Interop.Microsoft.Office.Core (from the Microsoft Office 16.0 Object Library reference).

I try to open a powerpoint using the following code:

My security knowledge is very old and I want to refresh my full stack development tools. I'm learning about Oauth2, JWT, Next.JS, Auth0 and stuff, but I don't know how to bring all of that together. Please be patient with me, I put efforts in that question :)

Let's say I want to build a web app, where a user can register to a building. He is entering his personal data and receives a human friendly checkin number (e.g. A00001 - Z99999).
