Hi. I'm trying to run VB code in visual studio form project but get an error when code is trying to run. Error is: "System.ArgumentException: 'Keyword not supported: 'trust server certificate'.'". The line in code affected is:

Data Source=CDOPWD-4023;Initial Catalog=PREVENTION_DATABASE;Persist Security Info=True;User ID=cesrivas;Password=***********;TrustServerCertificate=True

Hi @Cesar Rivas

Not all data providers or database systems support this option.

If you're working with a database system that doesn't support this option, you'll need to remove the TrustServerCertificate=True part from your connection string.

Best Regards.

Yes, after removing "Trust Server Certificate=False" from connection string
"Data Source= __ -LAPTOP\SQLEXPRESS;Initial Catalog=MovieRentalDb;Integrated Security=True;Pooling=False;Encrypt=False; Trust Server Certificate=False", it worked for me.

Modified connectionString :-

"Data Source= ____ -LAPTOP\SQLEXPRESS;Initial Catalog=MovieRentalDb;Integrated Security=True;Pooling=False;Encrypt=False"
