InvalidCastException in database constructor
Posted: Wed 19 Aug 2015 12:24
Hello,
I was given job to continue work on MySQL entity framework project and the project had working 8.3.363.6 (or something like that) dotConnect version. It has been a while since project was touched and trial on the connector had expired (exception was thrown) so I decided to update the connector since it had been informing me about the update for a while.
After I downloaded and re-installed the dotConnector for MySQL 8.4.464 I started to get this error message when code hits database (empty) constructor:
Error message it self is quite self explanatory, but I cannot underestand why project is using dll from C: drive (wrong version even) and then trying to convert it to version that is referenced to the project. I have not referenced the dll in windows folder.
Is this a problem with code? References? Expired trial?
I have put this provider in my app.config:
