Tutorial 1: Creating a Web Project and Connecting To the Database

To begin with, create an empty new ASP.NET Web Site Project (File->New Web Site) within Visual Web Developer. We can then connect and load our Northwinds database in the IDE. To-do this you can follow one of two approaches:

Option 1: Connect to a local or remote SQL 2000 or SQL 2005 database that has the Northwinds sample installed. To-do this, go to the "Server Explorer" property window in Visual Web Developer (choose View -> Server Explorer if it isn’t currently visible), right-click on the "Data Connections" node and choose to add a new database connection. You can then walkthrough a wizard to pick your SQL database and load the Northwinds database in the IDE:

Figure 1

Option 2: If you don’t have a SQL 2000 or SQL 2005, you can alternatively use the free SQL 2005 Express Edition. Download this .zip file containing the Northwinds.mdf database file, and copy it to the "App_Data" directory underneath your web site’s root directory. Click the "Refresh" button in the solution explorer, and it will appear in the Solution Explorer:

Figure 2

SQL Express databases within the App_Data directory will automatically show-up as a listed item in the Server Explorer property window (note: I sometimes get a timeout error the very first time I expand a newly copied SQL express database here – I think because it is generating the log file the first time it is accessed. If this happens just click it again and it seems to immediately expands

Figure 3

After the Northwinds database has been loaded using either Option #1 or Option #2 above, you can expand, view, edit, and add to any of the tables, stored procedures, views, triggers, etc with the database. You can also use the query builder to test out and run queries against the database (or right-click on a table and choose "Show Table Data" to see all of it).

I've been using ASP for 5yrs and felt the need to become current in my coding practices. I Spent 2 weeks trying to find a suitable method to work with Access DB so I could update my code and then update my DB to SQL. MS built in functionaliy is not very flexible. This functionality is so much better than RecordSet in ASP and your Demo actually Works. Good Job! Now I can get something done.

This is a great article telling the user how to setup a datasource HOWEVER it doesn't mention using the source in a web service (Microsoft got smart...they realized that the most time consuming part of the web service is getting data...therefore in the .NET 2.0 version they made it hard to create/use datasets in order to discourage anybody from using the web service)
