Xamarin Emulator works, but after updating Pro VS 2017 the app is copied but appears as blank

I use xamarin android player to do the simulations and test my apps but after I updated Pro Visual Studio 2017 the emulator works partially,I do the design in main.AXML and the build & deploy works normally,but in the emulator the app appears as blank.

Follow screenshot

I left 15 minutes so just to make sure that it was not some processing problem but nothing(it had already happened before in VS2015 that sometimes took about 3 seconds Pro app show its features but now it doesn't even want more)

Problem Solved

In Properties > Build

I enabled the options: Allow Unsafe Code and Optimize Code

And after another Build & Deploy the app worked as it should insert the description of the image here
