Rendering issues with our .Net application post windows patch

SusanA 0 Reputation points

Recently, we've encountered rendering issues with our .NET application following a Windows patch update for Windows 10 Version 22H2. Specifically, after applying the cumulative update for .NET Framework 3.5, 4.8, and 4.8.1, we've noticed intermittent problems with image rendering in our application.

One of our clients, who utilizes our application built on C# based .NET Framework 4.8 , reported sporadic occurrences of missing images. These images are stored on the web server where our application is hosted.

Could anyone else who has applied the same Windows update and .NET Framework cumulative update share their experiences? Have you encountered any performance issues or rendering glitches post-update? Additionally, has anyone faced similar challenges with missing images in web-hosted applications?

Any insights, tips, or potential solutions would be greatly appreciated.

Thank you in advance for your help!

    You mentioned a web server. What type of app is this? Web App? If so:

    • What version of the runtime are you targeting with it? Is your app MVC, Angular, what?
    • Can you clarify what isn't rendering properly? For example the images that don't load are static images in the content folder, images that are backed by an ASPx handler, generated from a controller, etc?
    • What does the browser show in these cases? The network tab will show you requests for the images and the results. Is the browser getting the image, getting garbage, getting partial, etc.
    • Do the images have any caching enabled? Do you have static or dynamic compression enabled on IIS?
    • Is this impacting all browsers or only some (and which one's)?
