Openiddict-core: Cannot serialize ImmutableArray<T> by MongoDb.Driver

[masakura]

MongoDb.Driver cannot serialize ImmutableArray <T>.

.AddCore(options =>
    {
        options.UseMongoDb(/* ... */);
   });

I get an exception when I run the application.

System.ArgumentException

A new nightly build with a potential fix was pushed to MyGet.org. Give it a try when you have a moment.

Just tried the nightly build, the serialization issue is fixed 👌

I tried 3.0.0-beta.6. OK!

Thanks!
