Hello NG,

as a newbie I am learning about asp.net 3.5.
To do this I bought a book form Microsoft Press (ASP.NET 3.5 Step by Step).
Also I prepared me a Windows Server 2008 with IIS 7.0 in a VM to test the
samples from the book.
I have installed the "dotnetfx35.exe" to the WS2008.

My problem now is, that - calling my default.aspx - I receive a errormessage
"CS0234: The Typ- oder Namespacename Linq is not in the Namespace System
available..."
What can I do to solve this problem?

Regards

You need to add a "reference" to the project, to System.Core.dll (on
the .Net tab).
A "reference" includes a library in your project, so you can use it's
classes. This is required.
A "using" directive only allows you to skip the namespace when you use
a class from that "used" namespace. This is more like "syntactic
sugar", tit makes it less complicated to write (and read) the code. You
still need the "reference".

Thanks for this infos. What ist the ".Net tab"? Is it part of the
InternetInformationServices?

I in the meanwhile brought my app to be able to run.
In the "book" I was told to copy a different web.config to a existing
(sample) website to add the "authentication" sample.
I remebered that this website worked before and therfor compared the
previous web.congfig to the new one and realized that in the new config the
section
<assemblies> ... </assemblies> was missing, which held the reference.

But back to my previous question, about the .Net tab. Is there a generic way
to enable IIS for .Net 3.5 assemblies?

No, this is not an IIS setting, you need to set this in Visual Studio.
If you don't have Visual Studio (there are free "express" editions),
then that <assemblies> section works similar.

Ok, now I know what you where talking about. I am working with VS2008
Professional and the .NET tab holds all necessary references.
The "bug" is in the book, which told me to "copy" a web.config not holding
the required references.

Thanks for your help!
