npgsql: EntityFramework 7 - The type initializer for 'Npgsql.TypeHandlerRegistry' threw an exception.

I’m currently trying EntityFramework7 rc1-1. I have no problem on Windows but I have this exception on Linux with coreclr when I try to add a migration.

System.TypeInitializationException: The type initializer for 'Npgsql.TypeHandlerRegistry' threw an exception. ---> System.Reflection.ReflectionTypeLoadException: Unable to load one or more of the requested types. Retrieve the LoaderExceptions property for more information.
