Null reference occurs here: https://github.com/protobuf-net/protobuf-net/blob/master/src/protobuf-net.Core/ExtensibleUtil.cs#L59

Full details:

This seems to be because TypeModel.DefaultModel is never initialized.

It seems to only ever be initialized by protobuf-net's RuntimeTypeModel, but attempting to use that from the new 3.0.0-alpha.174 package only results in MissingMethodExceptions, since the API surface of the various protobuf-net v3 packages don't seem to align.

this should be fixed in .75
