Description Jérémie Laval 2017-11-27 21:39:04 UTC
When using a NuGet package that downloads AARs dynamically (and thus is stored in `C:\Users\[user]\AppData\Local\Xamarin\` (like older support libraries or Google Play Services) the design-time build doesn't include those resources in the parsing even when they are present and unpacked by an actual build.

To reproduce create a Android app that references support libraries and note that:

 - If using 25.x.x then the Resource class contains all the right IDs
 - If using 24.x.x then the Resource class *does not* contain all the right IDs.


The managed resource generator only includes `AdditionalResourceDirectories="@(LibraryResourceDirectories)"` to parse extra resources which misses those that are coming from the cache. That Aapt task includes both:



No intellisense will be provided and red squiggles will be shown for any NuGet that uses the shared cache. Compilation will work though.

@gaurav, please re-test this with 15.6 builds... in d15svc (aka 15.5.3 and 15.5.5) the Android DTB feature is disabled, hence this problem does not occur. In 15.6 however, the feature has been re-enabled, and we need to make sure that this is fixed correctly therein.
