[Mono] Not switching to full .NET compatibility for plugins that require it results in unhandled exception in builds




Priority: 7Not yet prioritized for a release


Severity: 3Workaround is possible

When plugins require .NET 2.0, but .NET 2.0 Subset is selected in the Player Settings, Windows builds result in unhandled exception message on startup.

Steps to reproduce:
1) Open the latest attached project.
2) Build for Windows/macOS.
3) Run the build.

On Windows "Data folder not found - There should be 'test_Data' folder next to the executable." error window appears; the build does not start.
On macOS, the build is terminated instantly.
This exception should be handled properly instead.
Switching to full .NET 2.0 compatibility allows the build to run normally.

Reproduced on:
2017.1.0a4, 5.6.0f3, 5.5.2f1
