I'm working in Visual Studio 2008 on an app that uses strongly typed DataSets with MySQL as the backend. It seems like the dataset designer is losing the connection to the database so when I try to update the dataset, it can't read the metadata (tables/fields/datatypes/etc) and I either have to manually fix the XSD or close and restart Visual Studio to get it to reconnect. I think it has something to do with the idle connection timeout of the database (my DB client frequently complains that it lost the connection too, but at least it reconnects and continues on its way). I don't know how to change the idle connection timeout or to force VS to reconnect without restarting altogether. Can anyone offer any suggestions?
