Since I updated the Xamarin extension in Visual Studio 2015 to 4.5.0.443 (with Xamarin.Android being v7.3.0.13) Visual Studio continuously complains about not being able to copy portable library .dll files from .obj to .bin. Manually deleting the .dll files in the bin directories sometimes solves the issue but it keeps on re-appearing when doing new builds. Often however I can't delete the files and I get the message "Operation cannot be completed because the file is being opened in Visual Studio".
I am currently only testing on the android emulator and the issue almost always comes up when I force the debugged app to stop (using the "Stop debugging" menu in VS).
I am using xamarin.forms v2.3.4.231
Any idea? A temporary fix?
