Answer 1

There are 2 things you can try,

Ensure that Column encryption setting is enabled in your connection string. This can be done using a SqlConnectionStringBuilder object and setting SqlConnectionStringBuilder.ColumnEncryptionSetting to Enabled as follows

strbldr.ColumnEncryptionSetting = SqlConnectionColumnEncryptionSetting.Enabled;

If your stored procedure was created before you encrypted your column, you will need to refresh metadata for your stored procedure as follows

Use [Database]
GO    
--Do this for all stored procedures
EXEC sys.sp_refresh_parameter_encryption @name = '[dbo].[Clients_Insert]'
