Visual Studio 2017 and Mysql Datasource - Unexpected error and Could not retrieve schema information

Hi

I am using Visual Studio 2017 Community with MYSQL. I want to make windows form to update,delete records...etc.

When i use a datagridview and try to add datasource, at the very end it fails with these messages:

1.Some updating commands could not be generated automatically.
 The database returned the following error.
 Unexpected Error.

2.Could not retrieve schema information for the table or view.

I cant get this to work at all.

I have reinstalled my laptop Win10 three times.

I used all latest versions for Visual Studio, Mysql for VisualStudio and connector/net.

Then i used older version of each and still fails on the same spot.

Please help,
