We are using MySQL .NET Connector 6.7.4 to access a MySQL database using Entity Framework 5.0 in .NET. After upgrading to version 6.7.4 we have started to run into problems with a timestamp column where NULL is allowed. We can save values without problems (i.e. the column gets updated properly in the db) but whenever we retrieve the entity corresponding to the row in the database the property corresponding to that column always returns null. We have tried to change the precision of the column in the edmx-file but that didn't change the behavior at all. Has anyone else experienced this issue? Is there any known workaround, besides downgrading to an older version of MySQL .NET Connector?
