I’m trying to add a new ADO.Net Entity Data Model to an MVC project

  • 0

I’m trying to add a new ADO.Net Entity Data Model to an MVC project I am working on.

When I complete the wizard, choosing my db and tables (just a single table for now) I get an error “”Exception has been thrown by the target of an invocation.” and it throws me back the add new item dialog.

At this point, an empty Data Model has been created in my project. If I then choose “Update Model From Database” and complete the wizard again, I get a similar error.

An exception of type ‘System.Reflection.TargetInvocationException’ occurred while attempting to update from the database. The exception message is: ‘Exception has been thrown by the target of an invocation.’.

Any ideas? I have tried doing this in an empty project also and still no dice!

    You could try creating the Entity Data Model manually using the EdmGen.exe tool. Hopefully that will give a bit more information about the error.
