FormSample Crash/Build Issues

[v534]

I am creating a new ticket since adding a comment to issue #10 doesn't seem to reopen it.

I downloaded the latest FormSample files and updated to the latest UrhoSharp.Forms 1.0.557 and Xamarin.Forms 2.2.0.43, but still have the same issues. Do I need to wait for something further?

ISSUES:

1. Building in release mode fails.
2. Pressing the back button does not return to the previous page and instead freezes the animation.
3. Clicking the restart button after updating it to "restartBtn.Clicked += (sender, e) => Navigation.PushAsync(new UrhoPage());" causes the animation to freeze and eventually the following crash:

@v534 1) Building in release mode fails because of "Linker" issue (set it to None and it will be OK) - it's a knonw issue 2-3) the #10 issue is closed, but the fix for it is not in the 1.0.557 package

[v534]

Thanks @EgorBo! I'll wait for the next release.

[v534]

Hi @EgorBo can you please release the fix you have already made?

I downloaded the latest FormSample files again and updated to the latest UrhoSharp.Forms 1.0.557 and Xamarin.Forms 2.3.0.49, but still have the same issues (Navigating to UrhoPage() again freezes the urhosurface and eventually crashes, and also back button doesn't work)

Also for the linker issue, I'm not clear about your suggestion for how to "set it to None and it will be OK"

[v534]

@EgorBo , @migueldeicaza , @CartBlanche - is there anyone that can help get this fix released?

[v534]

@EgorBo can you please update UrhoSharp.Forms in FormsSample (as you have done for UrhoSharp in FeatureSamples) to resolve these issues?
