Issue
I spent all day today struggling with an issue when loading the AdaptiveCards netstandard1.3 library into my project (indirectly, via a bunch of complicated Assembly.Load() / AppDomain stuff that is only semi-relevant). Every time, my program would fail at startup with the exception:
FileLoadException: Could not load file or assembly 'AdaptiveCards, Version=1.2.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. Strong name validation failed. (Exception from HRESULT: 0x8013141A)
After much frustration I discovered that the netstandard1.3 dll was different from the other two in terms of strong name signing, in that it was only delay-signed but not "fully" validated. This is what was causing my runtime to fail to load them. Validating them manually with Sn.exe shows this:
C:\WINDOWS\system32>Sn -v "C:\Users\lostromb\Desktop\adaptivecards\net452\AdaptiveCards.dll"
Microsoft (R) .NET Framework Strong Name Utility Version 4.0.30319.0

Assembly 'C:\Users\lostromb\Desktop\adaptivecards\net452\AdaptiveCards.dll' is valid

C:\Users\lostromb\Desktop\adaptivecards\netstandard1.3\AdaptiveCards.dll is a delay-signed or test-signed assembly
Of course one option is to upgrade my project to one of the other runtimes, but my project is plugin-based and I'm trying to maintain the broadest level of compatability which is why I'd prefer to target the lower version. Would it be possible to fix this simple issue in the next release?
