From the developer:
Sometimes working with ADO.NET connection strings can be hard. Things suddenly stop working because of a connectivity problem a server problem or a bug in your code.Well, this little tool can help you get to the source of the problem. All it does is let you type/paste in a connection string and use that to try to connect to your database. But sometimes that's all you need.
