Imar,

Sorry for the dumb question, but:

Would you please explain to me why I need to install SQL Server Express when I already have installed Microsoft SQL Server 2008 and Microsoft SQL Server 2008 R2

I'm using Windows 7 with Microsoft Visual Studio 2010 Professional installed.

I'm in Chap 14, page 423, Try it Out, Number 1.

Thanks,

Hi there,

You don't *have* to install it, but it's convenient if you do. Many examples and tools (including VWD itself) assume it's there. So, if you have a SQL Server instance called .\SqlExpress, you can run many examples and use .NET features (such as Membership) out of the box. If you have a different SQL Server instance, you'll need to make modifications to connection strings and so on each time you run a sample or create a new web site.

FYI: I have multiple instances of SQL Server running side by side without a problem. I have the Developer edition for all the tools but also a SqlExpress instance for the reasons mentioned.

Cheers,

Imar
