Description:
The MySqlDbType.DateTime is not available in VB.Net.  As such, the warning "the datetime enum value is obsolete" is always shown during compilation.

How to repeat:
cmd.Parameters.Add("?dt", MySqlDbType.Datetime).Value = DateTime.Now

Hi Charles and thanks for your report.

Please take a minute to browse through c/NET changelog and you'll find this:
1. MySQL :: MySQL 5.1 Reference Manual :: C.3.17 Changes in MySQL Connector/NET 5.0.5 (07 March 2007)

    ... use of SchemaOnly or SingleRow command behaviors with stored procedures or prepared statements. Added *MySqlParameterCollection.AddWithValue* and marked the *Add(name, value) method as obsolete*. Return parameters created with DeriveParameters now have the name 

This behavior is deliberate and documented so !Bg.

Example:
      MySqlCommand cmd = new MySqlCommand("fnTest", conn);
      cmd.CommandType = CommandType.StoredProcedure;

      //cmd.Parameters.Add("?valin", 22); << Obsolete
      cmd.Parameters.AddWithValue("?valin", 22); << Ok

      cmd.Parameters[0].DbType = DbType.Int32;
      cmd.Parameters[0].Direction = ParameterDirection.Input;

Hi,
   I believe you have misunderstood my post.  The issue that was raised has absolutely nothing to do with the reply you have provided.  

To clarify, i code in both VB.NET and C#.  Codes in C# were compiled without warnings.  Only codes in VB.net were getting the warning.  

The issue is VB.net, being case-insensitive does not differentiate between "MySqlDbType.Datetime" and "MySqlDbType.DateTime" (Note the casing difference between the Date"T"ime)
