从数据库更新模型 | 视觉工作室 2019

Question

I need to add a new field in the database model.

I am trying to update a data model in .edmx file from the database.

Tried:

=> Removing the .edmx file and adding a new ADO.NET Entity Data Model containing EF Designer from database .

The wizard then asks for DB details and I checked Database in server explorer and the new field exist and database is connected. But still, the wizard closes without asking about the tables.

=> By selecting Update model from database but it showing me the same problem. The wizard close after selecting the MySql Database connection and database.

Below is the image of the wizard before it closes automatically.

Checked:

1. Using 'Mysql.Data.Entity.EF6' and not Mysql.Data.Entities
2. The version of 'Mysql.Data.Entity.EF6' and 'Mysql.Data' is same.
3. And more from StackOverflow's available solutions but none work.

Can anyone help me with updating the database model from the database? I have to add a new field in a table and update the models accordingly.

Answer 1

I was able to reproduce this error

Installed the latest "MySQL for Visual Studio" even though this screen says 2017 and 2019

I tried the connector from Oracle's download page and got this

With the connector from NuGet, I get your error when the wizard just closes (crashes I guess) without error

Answer 2

I'm able to update model from Database in Visual Studio 2019 using these versions:

MySQL Connector Net 8.0.21
MySQL for Visual Studio 2.0.5

MySQL for Visual Studio installed after MySQL Connector. Tell me if this works for you!
