Compile error

[awadh]

Hi there,
I downloaded OD V 21.2.36.0 and tried to compile. I get an error:
----
NuGet Package restore failed for project OpenDentBusiness: Unable to find version '6.9.9' of package 'MySql.Data'.
C:\Program Files (x86)\Microsoft SDKs\NuGetPackages\: Package 'MySql.Data.6.9.9' is not found on source 'C:\Program Files (x86)\Microsoft SDKs\NuGetPackages\'.
. Please see Error List window for detailed warnings and errors.
-----
I can see MySql.Data.dll file exists in Required dlls folder and still get this message.
I tried adding reference of MySql.Data.dll manually with Add->Reference->Browse, nothing happens.

what do I need to do? Please help.

Maybe right click on the Solution in the Solution Explorer tab and click Restore NuGet Packages?
