In Xamarin Android - How to regenerate the Resource.designer.cs
I tried to mark all the XML file\'s Build Action as \"AndroidResource\" and still the Resource.designer.c
I had the exact same issue and none of the answers here worked. Finally I figured that I had some image references in some layouts that did not exist yet. It seems if you have a broken source path, Resource.Designer.cs stops updating without any error. Finally after removing the reference images, the issue was resolved and the Resource.Designer.cs got updated.
Hope this helps someone!
