Creating The DataSet - Creating a Custom Membership Provider and Membership User utilizing a Data Set Table Adapter - Step 3
In this series, we are now ready to add a new Data Set. In the Solution Explorer, right click the DataSets folder you setup in the App_Folder and select the "DataSet" template item. Give your new dataset a name. In my example, I name it "SSNetDataSet.xsd." Now select "Add."
A new, empty DataSet will open. Then a dialog box will open asking you to "Choose your data connection." It will default to the connection as setup in your web.config file as shown below. Select the web.config data connection and then select the "Next" button.
