Recently, in order to test the sum function error problem in EF, I made a small demo with EF+mysql, and the result is that the error is reported as follows:

Method "MySql.Data.Entity.EFMySqlCommand.set_DbConnection(System.Data.Common.DbConnection)" attempts to access method "MySql.Data.MySqlClient.MySqlConnection.get_Settings()" failed.



Baidu later found that the version of MySql.Data used was too high, and the latest 8.0.15 was used by default

Solution 1: Change the version of MySql.Data to version 6.10.8.
Solution 2: Uninstall MySql.Data.Entity from NuGet and install MySql.Data.EntityFramework. (Not tested)

In addition, the test results are attached:
