Serialization Exception when openning Dictionary<> from different framework

When I try to open a PsiStore collected in a different framework (.NET Core) in a .NET framework program a serialization error is thrown:

System.Runtime.Serialization.SerializationException

I also find the reverse to be true too, but interestingly no error is thrown in PsiStudio.
Here is the code that generates the PsiStores:

namespace psi_dict_test
{
    using System;
    using System.Collections.Generic;
    using Microsoft.Psi;
    class Program
    {

        static void Write()
        {
            using (var p = Pipeline.Create())
            {
                var gen = Generators.Repeat(p, new Dictionary<string, int>() { { "hello", 1} }, 1, TimeSpan.Zero);
                var store = Store.Create(p, "write-w-core", "store");
                gen.Write("dict", store);
                p.Run();
            }
        }

        static void Read()
        {
            using (var p = Pipeline.Create())
            {
                var store = Store.Open(p, "write-w-core", "store");
                store.OpenStream<Dictionary<string, int>>("dict").Do(m =>{
                    Console.WriteLine(m["hello"]);
                });
                p.Run(); 
            }
        }

        static void Main(string[] args)
        {
            Read();
        }
    }
}

Here are the two generated PsiStores:
write-w-core.0000.zip
write-w-framework.0000.zip

Start with TypeSchema.ValidateCompatibleWith and GetCompatibleMemberSet in the stack trace, then follow ClassSerializer.Initialize through Importer.OpenStream. Reproduce the failure using the attached PsiStores and the sample Program.Read code. Done means stores written under .NET Core and .NET Framework can both be opened without a serialization exception.
