Initial Description
I removed several properties from my custom Profile class, and wanted to clean out the data from the aspnet\_Profile table. This code will remove all unwanted data from the PropertyNames and PropertyValuesString columns of aspnet\_Profile. Note this assumes PropertyValuesBinary is not used, though it wouldn't be hard to support that too.
