I just generated and downloaded v10.3.0 of the Angular + .NET Core app, and am having issues deploying to the Android emulator. Everything builds okay, but deployment fails with the following error:
Skipping target "_CopyConfigFiles" because all output files are up-to-date with respect to the input files.
Skipping target "_ConvertPdbFiles" because all output files are up-to-date with respect to the input files.
Migrated assembly to 'obj\Debug\100\android\assets\Platform.Xamarin.Android.dll'.
Debug symbols were found for the assembly, but they couldn't be used: Operation is not valid due to the current state of the object.
The process cannot access the file 'E:\SoftwareDevelopment\Platform\AspNet-Core\src\Platform.Mobile.Droid\obj\Debug\100\android\assets\Plugin.Iconize.pdb' because it is being used by another process.

I'm using the Angular + .NET Core for version 10.3.0 and using Visual Studio 16.9.5. Creating a fresh Visual Studio Xamarin project runs without issue.
