## Description

This is a Mono bug that has been fixed in Mono but does not seem to be in XA yet.

Mono bug report: bug #28777

I have attached a solution that has a Console project and an Android project. The test code from bug #28777 runs without exception in the Console project but throws in the XA project. Stack trace:

## Steps to reproduce

1. Open the attached test project and launch the Android project to device/simulator (Tested with XAP Nexus 5 Lollipop simulator)

Expected result: App will launch without exception.

Actual result: app crashes with exception noted above.

## Notes

I also tested with the Alpha build XA 6.0.0.0 and got the same results. This does not seem to be a regression.

The attached test is no longer throwing when compiled against master/b1574104.
