FlagsAttribute [Flags] is missing on FileCreationMode enum (and lots of other enums)

FlagsAttribute is not required, but should be set on all enums which can be combined.

Code analysis tools have this rule and detects inconsistencies.

It is fixed in master and will be available in the next alpha release.

I have checked this issue on following builds:

Windows 8.1
Xamarin Studio : 4.2.3 (build 60)
Xamarin.Android: 4.13.0 (Business Edition)

As per my observation, I have noticed that FileCreationMode enum has been marked as [Flags] attribute, but also noticed that the other or few more enums are not marked as [Flags].

Please refer the screencast: http://screencast.com/t/7sAUnjay2

Hence I am reopening this issue.

I am confirming this issue that many enums in Xamarin.Android that should have [Flags] do not have the [Flags] attribute and thus require workarounds to combine. I would list all these items in this bug report, but I believe a larger amount of investigation is needed.

I'm curious if we can find all these items using: https://developer.android.com/reference/android/support/annotation/IntDef.html and the "flags" = true to figure out where each enum needs a [Flags] attribute.
