Description Ruben Buniatyan 2017-05-11 14:54:24 UTC
# Steps to reproduce
Just run the attached project

# Expected behavior
Must work just fine

# Actual behavior
Throws MissingMethodException or similar error

# Supplemental info (logs, images, videos)
This was working smoothly before the VS 2017 15.2 update. In this case, seems the problem is with ValueTuple types.

@Ruben
Could you elaborate the issue. 
I am not able to reproduce this issue on my test machines. Detailed steps to reproduce and error would be very useful
Comment 3 Ruben Buniatyan 2017-05-15 12:48:50 UTC
There are two projects -- App3 and ClassLibrary1.
1. Open App3.
2. App3 references ClassLibrary1. If you don't see ClassLibrary1 in your solution, just add it.
3. Run App3, and you'll get a runtime error.
Comment 4 Ruben Buniatyan 2017-05-16 08:42:01 UTC
Any update on this? This bug turned my Android projects simply useless.
Comment 5 Mark McLemore 2017-06-23 22:48:15 UTC
Unable to repro with Visual Studio 2017 15.2, Xamarin 4.5.0.486, and Xamarin.Android 7.3.1.2. I did the following:

1. Opened the App3 .csproj file (creates a new solution).
2. Added the ClassLibrary1 project to the new solution.
3. Build > Build Solution.
4. Deploy to a Nexus 5 device running Android 6.0.1.

App3 runs without throwing an exception. I was able to leave it running on the device for several minutes.

Can you update to the latest version of Xamarin.Android and try it again? Also, are you getting this error on an emulator or on a device?

Comment 7 Jon Douglas [MSFT] 2017-08-21 20:36:09 UTC
I noticed this sample project is using project.json which was deprecated by the .NET team in favor for <PackageReference>. It has also been noted that multiple members were not able to reproduce this issue.

Thank you for taking the time to submit this report. After reviewing the description of this bug, we believe it no longer affects the current version of Xamarin.Android. If you are still experiencing the issue after updating your packages, please reopen this report with an attached reproduction.
