Trouble with MySqlCommandBuilder.DeriveParameters (no replies)

Hi everybody,

i shortly altered my SQL Server db class to work with mysql. Everything works fine, except using MySqlCommandBuilder.DeriveParameters to get the parameters of a stored procedure. I always encounter an InvalidCastException. Stored procedures without parameters are not affected.

MySqlConnection connection = new MySqlConnection(Config.ConnectionStringSql);

using (MySqlCommand command = new MySqlCommand(storedProcedure, connection))
{
command.CommandType = System.Data.CommandType.StoredProcedure;
command.Connection.Open();

at this line -> MySqlCommandBuilder.DeriveParameters(command);

I am using MySQL Community Server 6.5.15 and Connector/Net 6.9.6.0.


Any idea what is the source of this issue ?

best regards
