I’m using Mono/MonoDevelop on Mac OS, and I want an example for using SqlMetal

  • 0

I’m using Mono/MonoDevelop on Mac OS, and I want an example for using SqlMetal (DbLinq version included with Mono) for LINQ-to-SQL with MySQL database.

Oddly, I found many examples for SQLite, but none for MySQL. Examples found for MySQL seems to refer to the Microsoft’s SqlMetal.exe.

I tried to arrange my sqlmetal command from SQLite to adapt it for MySQL, but I have this message:

sqlmetal: Could not load databaseConnectionType type ‘ByteFX.Data.MySqlClient.MySqlConnection, ByteFX.Data’. Try using the –with-dbconnection=TYPE option.

Help is appreciated! Thank you.

    Find and edit your sqlmetal.exe.config and replace the settings not to use ByteFX (LONG unsupported) and use MySql.Data.

    Remember to include the fully qualified assembly name, in my case that line looks like:

    provider name="MySQL" dbLinqSchemaLoader="DbLinq.MySql.MySqlSchemaLoader, System.Data.Linq, Version=3.5.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" databaseConnection="MySql.Data.MySqlClient.MySqlConnection, MySql.Data, Version=6.2.3.0, Culture=neutral, PublicKeyToken=2f3544035097bf97"

    (I have MySql Connector installed with that version and token)
