I'm trying to use Migrate to AndroidX on my Xamarin project, but no matter what I do, I always get the File Modification Detected window, informing me that "The project '<myprojectname>' has been modified outside the environment." The migration goes no further. No matter what option I select in the File Modification Detected window, after selecting Migrate to AndroidX, I get this window again. I've tried unchecking 'Detect when file is changed outside the environment' in Tools > Options > Environment > Documents, and I've tried renaming the .suo file, but to no avail. I am using Git for source control, and I've also noticed that every time I select Migrate to AndroidX, the Git Changes windows shows that <myproject>.csproj has been changed. If I commit and push this change, it will show as changed again when I select Migrate to AndroidX.
