我们首先使用Entity Framework 6.2和MySql DB中的DB。开始在那里使用json类型，但无法将其映射到EF。在edmx文件中，我发现了错误，听起来像是：
<!--Errors Found During Generation:
warning 6005: The data type 'json' is currently not supported for the target Entity Framework version; the column 'customer_3rd_party_aws' in the table 'def.myquestworld_2.customer_3rd_party' was excluded.
warning 6005: The data type 'json' is currently not supported for the target Entity Framework version; the column 'customer_3rd_party_phonegap' in the table 'def.myquestworld_2.customer_3rd_party' was excluded.
warning 6005: The data type 'json' is currently not supported for the target Entity Framework version; the column 'customer_3rd_party_ios' in the table 'def.myquestworld_2.customer_3rd_party' was excluded.
据我所知，EF 6应该支持json类型，而6.2是当前版本。我错了吗？我该如何解决这个问题？
