Error when building uwp app in Release mode

Question

I have this app, that builds and runs successfully in Debug mode, on both my local computer and on my Windows Phone device, when trying with the Release mode, I get these 3 errors :

Error Internal compiler error: One or more errors occurred.

The non-generic type 'PInvoke.NTSTATUS.Code__PInvoke_Windows_Core' cannot be used with type arguments ...obj\x64\Release\ilc\intermediate\Liberte.Windows.Interop\SafeTypes.g.cs 333

The type or namespace name 'Value' could not be found (are you missing a using directive or an assembly reference?) ...obj\x64\Release\ilc\intermediate\Liberte.Windows.Interop\SafeTypes.g.cs 333

The actual code where the two last errors are detected is an auto generated code under a file named SafeTypes.g.cs and the line where the errors is raised is :

namespace PInvoke
{
    [global::System.Runtime.InteropServices.McgRedirectedType("PInvoke.NTSTATUS,PInvoke.Windows.Core, Version=0.1.0.0, Culture=neutral, PublicKeyToken=9e300f9f87f04a7a")]
    public unsafe partial struct NTSTATUS__PInvoke_Windows_Core
    {
        public global::PInvoke.NTSTATUS.Code__PInvoke_Windows_Core <Value>k__BackingField;
    }
}

I don't have any idea what does this mean, nor what should I do, any explanation and solution to this ?

Update :

Tried to Close VS, then Delete the Obj and the Bin content, rebuild again, but stuill have the same error.

I should mention maybe that I have reference to 2 other projects, one of them is a PCL project that uses PCLCrypto library, and the other one is a Universal App library that uses EntityFramework 7 pre-release with sqlight.

Update 2:

I tried to disable compilation with .Net native just to see what goes on, the release build succeeds, but the App crashes and quits just after startup.

Update 3:

I just discovered that the PCLCrypto library that I use in one of the two project I'm referencing, references two libs that are causing the problem, and they are mentioned in the errors above, I found this out when trying to uninstall the library to see if it is the cause of the problem :

I tried to rollback to a previous stable version, compiled in Debug mode, everything worked perfectly, when I try again Release mode with .Net native, I encounter a new problem : Out of memory.

You should try close VS, delete /obj and /bin folder in Project root directory, then rebuild solution — HelloWindowsPhone
Do you use .Net Native in Release mode? If "yes" - try remove it (in properties of main project) and try you way again. — Mykyta Bondarenko
@NikitaBondarenko thx for your comment, I've just tried that, the build succeeds, but that app crashes just after startup, any idea ?? — AymenDaoudi
Is the same exception or another? Any errors in Output window? You say that "the App crashes and quits just after startup" - after what? After constructor in App.cs or after navigating to first (main) page? — Mykyta Bondarenko

Concerning Update 3, it seems to be a bug with .NET Native tool chain, I opened an issue on PCLCrypto repo that was moved to corert repo
