Multi-​targeting in Express 2008?

I just wanted to check that this rumor of no multi-targeting in Express 2008 wasn't true as I'm looking in to possibly switching up to using Visual C# Express 2008 Beta 2 for working on my WPF app now that the designers seem a lot more stable and the whole IDE a lot faster.

Will multi-targeting remain in the express editions in the RTM version? I'm currently pointing my program at just .net 3 rather than 3.5 as I don't want to push too much extra download on to my XP users in one go.

Can someone confirm the features are staying in the free versions of Visual Studio?

The rumor is not true.

.NET3.5 is a new CLR and BCL version (woo & yay & hoopla for LINQ), .NET3.0, as you should know, is just those W*F libraries, it's all marketing, so if you're targeting .NET3 you're actually targeting .NET2

EDIT: Unless you already knew that, in which case I sound like patronising bastárd. My apologies.

From Visual C# EE 2008 Beta 2:

Hides the new libraries in .Net 3.0 from Intellisense, I assume (too lazy to check).

Nevertheless, the options there, so it probably does something

Well if you target v3.5 of the framework it will require users to have 3.5 installed regardless if you use the new features or not.  So if you don't want to require your users to install v3.5, you select 3.0.

Thanks for the replies, though I did know which CLR's worked on what versions.

Is this a known issue by the way or just me?

When I try to run some of the tools:

C:\Program Files\Microsoft Visual Studio 9.0\SDK\v3.5\Bin>sgen

Incorrect, 3.5 like 3.0 uses the 2.0 CLR.

Someone should create a version matrix.

Is this right then?

.NET	BCL	CLR	Compilers
1.0	1.0	1.0	1.0
1.1	1.1	1.1	1.1
2.0	2.0	2.0	2.0
3.0	2.0	2.0	2.0
3.5	3.0	2.0	3.0

And there is no Express public beta right now is there?

Um, yes, there is.

Haven't tried it to confirm/deny though.

Oh cool; must admit I'd never kept an eye on express.

No, normally I wouldn't either, but we're looking into running an XNA Express based course (including a lab full of 360s) so I've been paying slightly more attention than usual.
