Question

When I am running the application I am getting the following configuration error:

Authentication to host '127.0.0.1' for user 'root' using method 'mysql_native_password' failed with message: Unknown database 'kubota1'

Here is the connection string:

Answer 1

Try to specify the password value in your connection string. For now, it is missed.

Answer 2

are you able to connect database directly from MySQL workbench? if yes, then open Visual Studio > View > Server Explorer > Connect to Database. Enter required credentials and connect. If it is connected from Visual Studio then select database from Server Explorer >> Right Click >> Properties.

From there you can copy connection string and use in your code.
