App.config connection string Protection error
- by MikeScott8
I am running into an issue I had before; can't find my reference on how to solve it.
Here is the issue. We encrypt the connection strings section in the app.config for our client application using code below:
config = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None)
If config.ConnectionStrings.SectionInformation.IsProtected = False Then
config.ConnectionStrings.SectionInformation.ProtectSection(Nothing)
' We must save the changes to the configuration file.'
config.Save(ConfigurationSaveMode.Modified, True)
End If
The issue is we had a salesperson leave. The old laptop is going to a new salesperson and under the new user's login, when it tries to to do this we get an error. The error is:
Unhandled Exception: System.Configuration.ConfigurationErrorsException:
An error occurred executing the configuration section handler for connectionStrings. ---> System.Configuration.ConfigurationErrorsException: Failed to encrypt the section 'connectionStrings' using provider 'RsaProtectedConfigurationProvider'.
Error message from the provider: Object already exists.
---> System.Security.Cryptography.CryptographicException: Object already exists
