How to reproduce:
1. Create a new Unity project using "Lightweight RP" template
2. Open Build Settings window and switch platform to UWP
3. In the Player Settings, make sure that Scripting Runtime Version is .NET 4.x
4. Also, make sure that Scripting Background is set to IL2CPP
5. Build the project
6. Open the Visual Studio solution file generated in the Build directory
7. Deploy the build on the Local Machine (tested with "Debug" and "x64" options selected)

Expected result: After deploying, the Build launches without a crash.
Actual result: Build crashes when being launched.

Reproducible with - 2018.1.0b13, 2018.1.9f2, 2018.2.6f1, 2018.3.0a10

Note: Lightweight RP was introduced in 2018.1 (therefore the issue was not tested on versions prior 2018.1).

The exception that is thrown in the VS when the project crashes:
-----
