Are you deploying to your physical iOS device directly from Windows? With no Mac involved? Does it show the .NET splash screen or just a black screen?

You mention the bug is now back, is this something that has affected you personally before, or do you think that because you found the other reports?

I'll share a video today.

It doesn't matter how I deploy. The icon and splash screen that show are the first that were used when deployed. So, if I update and deploy to a different device/simulator, the new icon/splash appears. If I update and deploy to the same device, regardless of connected locally or remote via Pair to Mac, the icon/splash stay the same.

I did try the workaround of renaming the splash screen. Doing so insta-crashes the deployed app. I haven't grabbed the logs yet, but it only appears to confirm an issue exists.

I'm debugging this a bit more. I've thought for a moment if the build number doesn't change, the icon and splash will stay the same. If I change the build number, it will update. Same issue does not affect Android. Have not tried Windows yet. This is because I noticed when debugging my iPad via Pair to Mac it would update properly.

It does not matter if you clean the project/solution or delete obj/bin. It also doesn't matter if you uninstall. I'll work to get a video to show the issue if I can repro.

I then plugged the device back in to my Surface and debugged locally. The old icon came back.

What flag can I set to get the logs for when it's building and running locally vs. building and running via Pair to Mac / Remotely, please? Perhaps those will offer insight.

[AuriR]

OK here's a video of the issue. Note that if I deploy locally, the old icon comes back. If I connect to the Mac via Pair to Mac the new icon appears. If I connect a new device, the new icon appears. I did not record the latter, but the video should make what's happening clear.

This issue has been verified using Visual Studio 17.11.2 (8.0.80 & 8.0.82 ). Can repro on iOS local device platform.

OK here's a video of the issue. Note that if I deploy locally, the old icon comes back. If I connect to the Mac via Pair to Mac the new icon appears. If I connect a new device, the new icon appears. I did not record the latter, but the video should make what's happening clear.

This is the explanation right here.

If you deploy directly from Windows to your iDevice, you're using Hot Restart. If you look at the documentation and look under Limitations, you will find

Asset catalogs aren't supported. When using Hot Restart, your app will show a .NET icon and launch screen.

So this is expected and a known limitation. Closing this one as there is not much we can do here at this time.
This is not an issue when you deploy to the store, only for you locally when you deploy from Windows directly to your iPad.

Thank you so much for the video which made it all very clear!
