.NET 5 issue with PlatformAttribute

[FixBo]

On .NET 5 Preview 4 exception occurred when using PlatformAttribute.

An exception was thrown while loading the test.

Thanks for reporting this @FixBo. I've edited your message to use a code block for better readability. This would be good to get done before the release of .NET 5

Also, the tests fixtures that has at least one test with PlatformAttribute are not discovered by NUnit and cannot be run.
I have attached a sample project in which it is impossible to run tests in the Tests1 class.
Would you please tell when the next update 3.13 will be published to NuGet?

@AlexanderEgorov Just to clarify, are you saying that this issue is fixed in the current master, or is it outstanding? Can you file a new issue if not please, it sounds like a pretty big problem! 🙂

On 3.13, the team were holding out for the official release of .NET 5. @rprouse is currently working on getting everything up and running in #3666 and I believe is planning to release after that.

I've added this to the 3.13 release project. I'll download and look at your solution @AlekseyMartynov

I've tested @AlexanderEgorov's example with a recent build of NUnit 3.13 and it works fine. Testing with 3.12, I see the same issue as reported in this issue.

The Platform("NET") attribute causes the one test to be ignored when using NUnit 3.13. That is correct since it is actually .NET Core, but I thought the code @jnm2 added would address that. We've only just kept the Platform attribute working and don't update it, so I've entered #3669 to decide how we should posisition it.
