"Unloading broken assembly" error message provides insufficient information




Priority: 3Not yet prioritized for a release


Severity: 1Crash, freeze, data loss, work stops

Steps to reproduce:
1. Open attached project ""
2. Upon launch you will see the "Unloading broken assembly Assets/Microsoft.ProjectOxford.Face.dll, this assembly can cause crashes in the runtime" error
3. The .dll is just missing dependencies which you can import from attached ""

Expected: The manifest of the DLL has information about dependencies, which could be exposed and shown in the error message for clarity
Actual: Error message says dll is broken which could mean a multitude of things

Reproduced on 2018.1.0b7, 2018.1.0b1

    Reproduced on Unity 2018.3.0b8, only happens when Scripting Runtime set to .NET 4.x . Error disappears when I set .NET 3.5.

    The thing I noticed is error happens when loading DLL built with .NET 3.5

    This bug has been fixed in Unity 2018.3

    Currently, there is no plan to backport it to older versions.
    Use the newer Unity version to avoid encountering this bug :)
