We will be looking at design issues relating to concurrency control and updateability when using key Visual Studio controls such as the FormView and ListView controls. So if you don’t know where to start in choosing between SQL, LINQ and Entity datasources then you will by the end of this talk. We will also take a look at techniques for the seamless integration of ASP.net security with SQL Server Login security for web applications using LINQ.
