I recently updated visual studio to 17.14.17. I am now not able to create a new project that I can add items to a form from the toolbox. I can add the item, but it is invisible. I completely uninstalled visual studio and went through the process of installing the required components and adding the extension for version 4.0.2. I was not asked for the license key, but I see it is correct if I click on the icon in the designer. Changing to explorer makes no difference. Also, I can build the solution, but if I try to run it, IIS Express tells be it can’t reach this page. The attached sample is my attempt to create a basic application. I am not doing anything different than I have before. I can see the nuget packages are loaded correctly. I am obviously missing a step.
Hi John,
Like my colleague Julie pointed out, the latest Cumulative update (KB5066835) for Windows is what’s causing the issues you’re having.
It essentially made the IIS services not work, everything would work fine if you uninstall the update!
Best,
Alaa
I tested your sample and it runs fine on my machine. So it’s an issue with your machine.
This is actually windows related, not Visual Studio related. You need to uninstall the KB5066835 update.
