Executing a command that resulted in a fatal exception did not close the connection. (Bug#37991)

In a .NET application MySQL Connector/NET modifies the connection string so that it contains several occurrences of the same option with different values. This is illustrated by the example that follows.

The original connection string:

  host=localhost;database=test;uid=*****;pwd=*****;
  connect timeout=25; auto enlist=false;pooling=false;

The connection string after after closing MySqlDataReader:

  host=localhost;database=test;uid=*****;pwd=*****;
  connect timeout=25;auto enlist=false;pooling=false; 
  Allow User Variables=True;Allow User Variables=False;
  Allow User Variables=True;Allow User Variables=False;

Using the MySQL Visual Studio plugin and a MySQL 4.1 server, certain field types (ENUM) would not be identified correctly. Also, when looking for tables, the plugin would list all tables matching a wildcard pattern of the database name supplied in the connection string, instead of only tables within the specified database.
