VS2005 and LINQ

[Rainer Queck]

Hello NG,

Is it possible to use LINQ together with VS2005?
If yes I assume I need some AddIns. Where can I find then?

Thanks for hints and links.

Well, there's all the old betas and CTPs which worked on VS2005 - but
they're all out of date.

Basically you need VS2008.

If possible (I haven't tried) it would be extremely tricky; in
particular, to write "where" clauses on IQueryable<T> etc requires the
construction of an "Expression"; this is not something I would want to
have to do routinely, especially for non-trivial queries. The lack of
anon-types would be irritating but not insurmountable.

If you just mean LINQ-to-objects you might *just* be able to get it
working with anon methods instead of using lambdas for the predicates/
selectors, but you'd need to use the long syntax to the extension
methods *and* you'd need to write backwards:
select(orderby(where(from))) [but much longer].

Basically, I wouldn't try it. I strongly suggest using 2008; the
express edition may do most of what you want? Note that in either case
you will want to reference the .NET 3.5 assemblies; you can't avoid
this necessity.

Hello Marc,

thanks for your information. Actually I am using VS2008, but I have a
Classlibrary-Project in use, some one would like to add to his project too.
Unfortunatelly he is still using VS2005 and his "Boss" is - momentarely -
not willing to upgrade to VS2008 :-(

Well I guess if he wants to make use of my library source code, he will have
to extract the code needed and build a library for his own.
Luckily he needs no modules, using LINQ.

Thanks

Hang on - so he doesn't actually need to use LINQ? In that case why
can't he just reference your DLL?

Hello Jon,

Because he wants to use my source code as well.

Hi,

Make it simple, download VS2008 Express edition

Now you confused me, what about the original question regarding linq?
Or why is linq mentioned at all ?

Hello Ignacio,

In parts of my classlibrary I make use of LINQ, but it is a part not needed
by the "other one".
So it would come in handy, if he could just build his own VS2005 class
librayr by assimilating my code.
But as it looks now, he must remove the parts of my code, which uses LINQ.

Hi once more,

Make it simple, download VS2008 Express edition

Well, the one who wants to use my class library, would like to add it to his
solution which is a "not that small" project under VS2005 pro AND
because of his boss, he can't switch to VS2008.

Rainer

With Microsoft DreamSpark as a student VS2008 should be free.
