Description
The XmlSerializer in collectible ALC can use the direct types from the ALC fine, but if the type is wrapped inside a collection like List, then it will throw System.NotSupportedException: A non-collectible assembly may not reference a collectible assembly.
Reproduction Steps
Get this repo: https://github.com/uffebjorklund/AssemblyLoadContextBug
Change line 10 of https://github.com/uffebjorklund/AssemblyLoadContextBug/tree/master/Module/Foo.cs to use typeof(List<Bar>) instead of typeof(Bar)
Run CrashSample, see the System.NotSupportedException: A non-collectible assembly may not reference a collectible assembly.
Expected behavior
The context created successfully just like when using typeof(Bar).
Actual behavior
It throws with System.NotSupportedException: A non-collectible assembly may not reference a collectible assembly.
Regression?
No
Known Workarounds
The collection can be wrapped in another class so that it can be used with XmlSerializer

Other information
I'm not very sure if this is a bug or an intended behavior. But there is some use cases where we want to use a collection directly and not wrapping it with a class.
