One of the features of EF CodeFirst is the ability to automatically drop and recreate a database if the model changes or if the database does not exist, which is pretty useful when just doing development work. In a web app this is done in the Global.asax file within "protected void Application_Start()" as per this post from Scott Guthrie - http://weblogs.asp.net/scottgu/archive/2010/07/16/code-first-development-with-entity-framework-4.aspx . An example would be: protected void Application_Start() { Database.SetInitializer<yourdbcontex>(new DropCreateDatabaseIfModelChanges<yourdbcontext>()); AreaRegistration.RegisterAllAreas(); RegisterGlobalFilters(GlobalFilters.Filters); RegisterRoutes(RouteTable.Routes); } However when using the Database.SetInitializer and trying to rebuild the database, the following exception may be encountered, especially if using SQL Server Express: "This operation requires a connection to the 'master'...

There are other unit testing frameworks available (MSTest, nUnit, etc.). There are pro's to each and some better than others but xUnit is pretty straightforward to get up and running with the VWD 2010 Express version. Download and Install xUnit The xUnit project can be found at: http://xunit.codeplex.com/ . Downloads are available from http://xunit.codeplex.com/releases/view/62840 .

The following SQL function will remove and strip all non-alphanumeric characters from a string. CREATE FUNCTION [dbo].[fncRemoveNonAlphanumericChars](@Temp VarChar(1000)) RETURNS VarChar(1000) AS BEGIN WHILE PatIndex('%[^A-Za-z0-9]%', @Temp) > 0 SET @Temp = Stuff(@Temp, PatIndex('%[^A-Za-z0-9]%', @Temp), 1, '') RETURN @TEmp END Example: SELECT dbo.fncRemoveNonAlphanumericChars('abc...DEF,,,GHI(((123)))456jklmn') Result: abcDEFGHI123456jklmn
