Entity Framework Wizard Encounters Errors in MySQL Database Integration
Entity Framework (EF) offers database-first modeling capabilities, allowing seamless interactions with various databases like SQL Server and MySQL. However, users may encounter crashes during the EF wizard when updating the model against a MySQL database.
One such scenario is when developers attempt to interoperate an EF model between SQL Server and MySQL databases. The application queries either database based on connection settings, ensuring synchronized schemas. While supporting EF with the SQL Server database, attempts to update the model against the MySQL database result in crashes.
The image below illustrates the wizard where the crash occurs:

Troubleshooting steps include reinstalling MySQL tools for Visual Studio, but this does not alleviate the issue.
A strange but effective solution was discovered using the NuGet Package Manager:
- Remove theMySql.Data.Entity package and its dependencies (including MySql.Data).
- Run 'Update model from database...' within the .edmx file.
- Reinstall Entity Framework via NuGet Manager.
This approach has been reported to work by a user, although the reason behind its effectiveness remains unclear. It is recommended for others to validate this solution and provide further insights.
