VS2008: should data sets be placed in App_Data?

[dan]

I'm working on a small Web project in VS2008. In VS2005 it was recommended
that DataSet be placed in App_Data folder (the framework did that
automatically). In VS2008 the framework does not give me that option. The
Add.New Item in the App_Data context menu does not even list the DataSet.

Does anyone know what is behind the change and what the recommended practice
is?
Thanks.

Datasets are usually stored in memory, as an in-memory database.

Are you writing the Dataset to a file ?
If not, using App_Data doesn't make sense.

Try to add them from the main menu. It should suggest to add them in
App_Code...

It looks like to me you are confusing DataSets with data files (such as a
SQL Server MDF file) ???

In VS2008 it does not suggest as it used to in VS2005. The only way to
place DataSets (i.e. xsd) in App_Code is to drag them into the folder after
creating them. It is not a big deal but I'm curious what the best practice
is.
Another difference is that when you Add a DataSet the TableAdapter wizard is
no longer automatically launched.
Does your VS2008 behave like VS2005 in the above scenarios?

And I don't mean data files.

I did not mean instantiated DataSets objects at run time. I was referring
to the process of creating/adding strongly typed data sets to a project in
VS2008 (i.e. Solution Explorer.Add New Item).

Yes, I have the same behavior that is if I chosose "WebSite", "Add new
item", "Dataset" it suggest to add to app_code. BTW which model are you
using for your project (web site or web application ?)

I just noticed that made a silly mistake in my original post. It should've
read 'App_Code' instead of 'App_Data'.
Sorry about the confusion.

I'm going back to VS2005. Could not get it to work. I've got also other
issues with VS2008: no table templates, no ATL server libraries for native
development, etc. Simply not worth the trouble.

Thanks to everyone who tried to help.

I created a new project (i.e. web application) instead of new web site as I
used to in VS2005. I was happy to see the model back (i.e. like in VS2003).
Thanks for bringing it up. Do you think that could've made a difference?
I'll try web site later today.
Do you know if best practices are different for web applications? Any links
that deal with the subject?
Thanks
