Hi, I would like to reverse engineer a MySQL DB and failed in putting a PersistenceMapperMySQL to the form designer. I am using VS 2017 with MDriven 18.104.22.16802.
--------------------------- Microsoft Visual Studio --------------------------- Failed to create component 'PersistenceMapperMySql'. The error message follows: 'System.InvalidCastException: Unable to cast object of type 'Eco.Persistence.PersistenceMapperMySql' to type 'Eco.Persistence.PersistenceMapperDb'. at Eco.Persistence.Design.PersistenceHandleDesigner.InitializeComponent(IMapperVerbConfigurator configurator) at Eco.Persistence.Design.MySqlPersistenceHandleDesigner.InitializeNewComponent(IDictionary defaultValues) at System.Drawing.Design.ToolboxItem.CreateComponentsCore(IDesignerHost host, IDictionary defaultValues) at System.Drawing.Design.ToolboxItem.CreateComponents(IDesignerHost host, IDictionary defaultValues) at System.Windows.Forms.Design.OleDragDropHandler.CreateTool(ToolboxItem tool, Control parent, Int32 x, Int32 y, Int32 width, Int32 height, Boolean hasLocation, Boolean hasSize, ToolboxSnapDragDropEventArgs e)' --------------------------- OK ---------------------------July 20, 2017 at 10:48 am #5165
Most likely is it that the one you find in the toolbox is not pointing to correct version. Try adding C:\Program Files (x86)\CapableObjects\MDriven\7.0\bin\Eco.Persistence.MySql.dll to the toolbox manually
Also search for different old versions on this and removeJuly 24, 2017 at 1:37 am #5167
Hi, I have checked the component should be of the same version as the framework…. see the attached screenshot.

Go to the GAC and see:
Remove all Eco.Persistence.MySql versions but the one you want.
(you may need to close VS to remove file lock)
After this there is only 1 Eco.Persistence.MySql for VS to find.
(at this point I am not able to answer why Eco.Persistence.MySql behaves this way – I suspect it is that we upgraded the MySql.Data.dll – and that Eco.Persistence.MySql.Design uses the new one – VS finds an old Eco.Persistence.MySql i the GAC and thinks its fine – but Eco.Persistence.MySql.Design cannot talk to it)July 28, 2017 at 1:20 am #5174
Thank you very much for the tips! After removing all obsolete versions and set “Specific Version” to false in the IDE, it is working now. BTW, I need to use connection string instead of a MySQLConnection component perhaps due to version mismatch? The one I use is 6.9.9 instead of 6.9.8 since I can no longer find 6.9.8 on the official Oracle site. Here is the list of MDriven related assemblies with obsolete versions on my machine (all files are removed by now):
