When starting the installer, I get the message: "Cannot find a valid Product to install LINQ with" and then tells me that I need a version of Visual Studio 2005 installed in the next dialog.
I do have Visual Studio 2005 Professional (German) installed and I never had such problems with other previews that involved VS 2005 (e.g. Orcas).
I believe that the problem is related to the german language version of VS 2005 since there was also a language problem in the last preview (you had to copy some files after installation).
Does anyone have a workarround for this?

Thanks!

Hello Thomas,

Thanks for trying out the preview. There is a similar question on the forum (not sure if you posted it or someone else) -
http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=394174&SiteID=1

Unfortunately as mentioned in the readme, we did not have time to test this on non-English locales. There is a workaround as posted on the forum entry above. Depending on how adventurous one wants to be, one could try that. But in general, supporting other locales is one of the goals of productization of the preview; i.e. in the future.

Thanks again for trying out LINQ.

What ever happened to Object Spaces?

Is LINQ intended to be used instead of an object/relational mapping framework like ObjectSpaces or nHibernate? Or could it be used *with* one of these frameworks?

Hello Soma,

This article was posted on Data Access blog recently :

== On Future Versions of ADO.NET ==

Once you are done with shipping large products such as SQL Server 2005 and Visual Studio 2005 you’d expect to have a quiet time for a while, slow down a bit, that kind of stuff…

Turns out that it wasn’t the case this time. Right after SQL Server 2005 and Visual Studio 2005 were ready to ship (and actually even before they were completely done) we started to work hard on the next version of the data programming technologies; we worked on a broad vision that spans various releases and various technologies, and also specifically on how ADO.NET plays in that vision.

In the context of the vision for data programmability and ADO.NET, we decided that the next big step for ADO.NET was to move to a higher-level of abstraction. Connections, commands and readers are great for low-level stuff, but it’s not exactly what you want to be dealing with continuously when writing business logic. There are other aspects that are similarly “low level” and applications have to deal with, like the actual database schemas (e.g. did you even wonder why you have to do a 3-way join just to navigate a relationship between entities instead of just saying “traverse the relationship”?).

Today we’re making public our vision on data programmability, it’s a great read, I highly recommend it.

We’re also making public the specific plans for the next version of ADO.NET, a bit more technical, less formal, but with all the details of how we’re moving the technology forward.

Also check out Channel 9, we’ve recorded a few videos that discuss the next version of ADO.NET from various angles. The first one of the series has been posted there already; it features Mike, Tim and myself talking about what we’ve been working on for the next version of ADO.NET, including some high-level descriptions, details on the various services that are being introduced and some live demos.

Sam, the product unit manager for the data programmability team in Microsoft, has posted a blog entry that introduces the vision and the first round of concrete innovations around it.

Feedback on all of this stuff is welcome. I highly encourage folks to check out all of the content we’re putting out there and write us with your thoughts.

== ADO.NET mapping screencast ==

So,

Now that we are talking about the upcoming ADO.NET Entity Framework, I thought it would be interesting to do a screencast on our mapping infrastructure. If you have seen our vision on data programmability you will see that one of our investments is in using view maintenance technology to replace the common case-by-case mapping scenarios that ORM solutions typically employ.

Feel free to take a look at the screencast to see examples of us modeling and mapping simple inheritance, complex types and entity splitting. In future screencasts I will go into more detail about our metadata infrastructure, modeling and more on mapping.

We look forward to hearing your feedback!

Could you tell us why have you (MS) removed all publications about ADO.NET V3 ?

Cheers,

Sami

As far as I can see, there is no working workaround for the problem that Thomas indicated yet (installing the preview for the German language version of VC# Express). I urgently need LINQ for a university presentation. (Otherwise I have to torture my fellow students with Haskell ;-)

Does anybody know whether installing the English VC# Express will help, or whether this is a problem regarding the German version of Windows?

Thanks,
Chris

Jake asks
>What ever happened to Object Spaces?

ObjectSpaces is no longer a component of any Microsoft product. Several members of the team that worked on ObjectSpaces are currently on the LINQ project and working on various LINQ project components including DLinq.

DLinq is the ORM component of the LINQ project. In principle, you could implement another ORM with LINQ if you want to. But my personal take is - why bother when we are building DLinq for you. I doubt you can use LINQ with ObjectSpaces since ObjectSpaces is not continuing ;-)

Thanks.

Chris,

We did not really have the resources/time to test the preview on non-English locales. That is one of the tasks we do for productizing previews. So I am reluctant to suggest untested workarounds.

You may want to use the LINQ forum for more information and experience of LINQ users on non-English locales.

if "ObjectSpaces is no longer a component of any Microsoft product"

Can it be released to the public for those that want to use it in the intern?

I want something to work with now, not when Orcas is out :)
