Pocket PC Forum / Developers / Platform Builder / October 2008Adding both .NET 2.0 and 3.5
I am not able to run .NET CF application if I add both .NET 2.0 and .NET 3.5 to my CE5.0 x86 platform. If I only add either of them there is no problem! Visual Studio 2005 and 2008 displays following messages when I try to run a CF2.0 application in debug mode: "This application requires a newer version of the Microsoft® .NET Compact Framework than the version installed on this device." NETCFCFG.exe displays following version numbers on my platform: If I add only .NET 2.0 ==> 2.0.7045.0 (ROM) If I add only .NET 3.5 ==> 3.5.7338.0 (ROM) If I add both: 2.0.7045.0 3.5.7338.0 (ROM) I have added all CE updates that are available. It looks like that if I have only .NET 3.5 then I am able to execute both 2.0 and 3.5 programs in debug mode using VS2008. However I am not able to use VS2005 for .NET 2.0 applications. What can I do to have both .NET CF´s working on my platform for both VS2005 and VS2008. Tanks Ingibergur/Beggi You don't want to add both. There's no reason to have them both and they don't work when you try to do that. If you need to run .NET CF 3.5 applications, then add .NET CF 3.5 and live with it. You'll still be perfectly able to run .NET CF 2.0 applications on the device... However, as you've found, you can't DEBUG from VS2005 (because the version of the framework on the device is .NET CF 3.5 and VS2005 doesn't know about that). That's just the way it is.

In Windows CE 5.0 you could not add both .NET CF 1.1 and .NET CF 2.0  SignatureLuca Calligaris www.eurotech.it > You don't want to add both.

There are so many different meanings out there When .NET 2.0 arrived I was adviced by this group just add .NET 2.0 and keep 1.0 and nobody had an objection. However I did not follow this advice until now. Also everyting points to that direction that these versions are able to live together: - They live to gether on a PC - Platform manager allows all versions to be added - NETCFCFG is able to display all the .NET versions at same time. - I have not been able to find description on MSDN that they do not. - etc etc. It would have been a lot easier if Microsoft had written a small message together with the .NET 3.5 that it can not live together with .NET 2.0 Thanks again. Also if you read the documentation that follow the *.msi (installable) version of 3.5.

Not the same code, not the same run-time. Nothing. Drawing conclusions about any aspect of Windows CE from how XP or Vista works is guaranteed to lead to bad guesses. > - I have not been able to find description on MSDN that they do not. If you find a suitable page where it could be described, use the Send Feedback link on that page and tell them to do that. They will do it. > It would have been a lot easier if Microsoft had written a small message > together with the .NET 3.5 that it can not live together with .NET 2.0 I'm sure they never tested it. You can install a later version over the top of an earlier version in the filesystem and the right things will happen. This is not so easy to achieve when you're building a bunch of different versions of things into the OS, each of which should be independent. Yes, they screwed up by not completely replacing all of the .NET CF 2.0 components with .NET CF 3.5 components when you add that from the catalog, but it's not so easy to do that in the other order. If .NET CF 3.5 is installed and you add .NET CF 2.0, it doesn't know about 3.5, unless the QFE that installs 3.5 also modifies a bunch of 2.0's build files, etc. It should be in the help, though. Paul T. They *can* coexist on a device. PB just can't deploy both to the same image and as Paul pointed out, there's no reason to ship both on a device anyway. SignatureChris Tacke, Embedded MVP OpenNETCF Consulting Giving back to the embedded community http://community.OpenNETCF.com > Thank you both for your answers. > [quoted text clipped - 66 lines] >>>> Tanks >>>> Ingibergur/Beggi I can think of at least one reason why I want to ship both versions. Giving my customers opportunity to choose between VS2005 and VS2008. Not everybody wants to change compiler everytime there is a new version with lots of new "smart" features. And to me, as PB can not deploy them both correctly to the same image, then they can not coexist and that should be documented by Microsoft. Beggi > They *can* coexist on a device.

The Windows folder on my device is RAM based. I have a "\Hard Disk" folder that is flash. I wonder if the CAB file can install it self in the \Hard Disk folder or will it install in the Windows folder? In other words, is it possible to choose a folder where it is installed.
