Hi Deepa,
We have checked the VS 2019 designer issue and confirmed the issue in imageEditor source. We have fixed this issue and it will be included in our upcoming weekly NuGet release which is scheduled to be roll out on 16th July,2019.
After fixed that issue, we faced another issue “when inflating the layout in source level” which related to framework level issue occurred in VS 2019 version. The Microsoft team resolved this issue and the fix we will be available in next Android SDK release version.
Thanks,
Santhiya A
