If you are here, I’m expecting that you encountered the same problem as mine. I was transferring a DataSet file to another project solution in Visual Studio, and I got this error “An unexpected error occurred in the .Net Framework Data Provider for MySQL.” I don’t really know what was causing the problem. So I did some searching and found a way to solve this.
Note: This is a temporary solution. Therefore you must update the latest and greatest version of MySQL Connector as soon as it is available.
Unexpected error occurred in the .NET Framework Data Provider Cause:
This problem exists if you installed MySQL Connector along with your visual studio. An easy fix was to uninstall the MySQL connector or MySQL itself. But if that is not the case. Follow the steps below.
This post describes step by step guide to fix an unexpected error occurred in the .NET Framework Data Provider for MySQL.
Let’s Start:
Note: modifying registry may damage your system. So It would be best to back up it first before changing anything.
First, Close all instances of Visual Studio, then open Regedit by simply opening the run command. Input or Type Regedit to the command and press enter. The registry editor window will be open.
Second, Navigate to this location
- HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\VisualStudio\10.0\DataProviders
Third, Rename the subkey which Default value reads .NET Framework Data Provider for MySQL or .NET Framework Data Provider for Oracle . This will serve as our backup in case we made a mistake. In my case it is ({8F5C5018-AE09-42cf-B2CC-2CCCC7CFC2BB}.This step backs up the subkey in case anything goes wrong.
Lastly, close registry editor and reopen your project.Hopefully it fixed your problem like as mine.
