Debug build works fine, Release build breaks?

Question

Trying to publish my UWP app. I'm able to build Release versions fine (I was actually able to push to the Store), but my app crashes as soon as it's launched. But the debug works fine?

I'm getting this error when debugging a Release build:

Unhandled exception at 0x55BA32F9 (Windows.UI.Xaml.dll) in AppName.exe: 0xC000027B: An application-internal exception has occurred (parameters: 0x00A12450, 0x00000002).

And these errors in Event Viewer if I launch it outside of VS:

1st:

Activation of app AppName failed with error: The remote procedure call failed. See the Microsoft-Windows-TWinUI/Operational log for additional information.

2nd:

Faulting application name: AppName.exe, version: 1.0.0.0, time stamp: 0x560c53bd
Faulting module name: Windows.UI.Xaml.dll, version: 10.0.10240.16431, time stamp: 0x55c9b90a

Faulting application path: C:\Development\AppName\AppName\bin\x86\Release\AppX\AppName.exe

Is there something I'm doing wrong? I don't get any errors or warnings on Debug.

向app.xaml.cs文件未处理的异常事件中添加一些代码，以将错误文本发送到网络服务或类似Google Analytics（分析）之类的东西，以便您查看发生了什么

Ended up being an issue with Entity Framework when it is compiled in .NET Native. I had to switch to SQLite for what I was using it for. Seems to work fine now.
