Answer 1

Right-click on your project in solution explorer and select " Manage NuGet Packages.. ".

1) Check which version of the Google.Protobuf package you have and remove it from your project.

2) Retry to install your MySql.Data package.

3) Then check if the version of Google.Protobuf installed with your MySql.Data is ok compared to the old one. If necessary, use the Package Manager to upgrade the Google.Protobuf package to the last recent version.
