Upgrading Pomelo.EntityFrameworkCore.MySql to verison 6.0.0 requires MySqlConnector 2.0.0. linq2db.EntityFrameworkCore throws this exception when using with the new version of MySqlConnector:

This may be an issue with linq2db itself actually, may need to move this issue there.

Yes, mysqlconnector 2 changed API and we don't support new signatures yet.

MaceWindu commented 2 years ago

Will try to include it into tomorrow's release of linq2db
