Description:
The database column I am trying to update is of "mediumtext" type. Yet when I try to update it from my code, the value gets truncated to 255 characters.

How to repeat:
Create a DBContext with an entity with a medium text database type. 

Suggested fix:
NA

More information.

Instead of using entity framework, I switched to using plain old MySqlConnection/MySqlCommand classes. Inserts and updates seem to work now. I guess the bug is in MySql EF layer.

Please look at my post on stackoverflow:

I see.. thanks for clarifying that. The issue could be in the Mapper for EF Core. 
This fix would be included for the next release of the series 6.10.x.
