xamarin.Android.Support.* does not exist warning

[JimJeon]

Also i have unknown enum constant warnings...

I just deleted /packages/ folder to remove from repo. (Q1. there is any other way to remove file from repo without deleting the file)

And I opened project, and updated my NuGet packages.

After update, i did build my project...and got ERRORs...

Q2. How to solve this problem...

i solved with this.

it can be occurred with corrupted packages.

1. Delete appdata/local/Xamarin/zips and /appdata/local/Xamarin/xamarin.android.support.*
2. Delete /packages/xamarin.android.support.* in your project
3. Delete obj and bin folders in your project
4. Open project and rebuild.
