.NET Framework 3.5 Service Pack 1 Beta and Expression Blend

.NET Framework 3.5 Service Pack 1 Beta and Expression Blend

  • Comments 27

Recently, a beta of .NET Framework 3.5 Service Pack 1 was released. There is currently an incompatibility with Expression Blend/SP1, Expression Blend 2, and Expression Blend 2.5 March 2008 (whose version number is 2.1.1111.0) where Blend will not work if you have .NET Framework 3.5 SP1 Beta installed.

We currently have a version of Expression Blend 2.5 March 2008 Preview (referred to as Blend 2.5 Preview from now on) that fixes this incompatibility, but you will only be able to create and edit WPF and Silverlight 1 projects. While Blend 2.5 Preview will also allow you to create and edit Silverlight 2 projects, they are not supported by Visual Studio at this time.  If you are doing any Silverlight 2 development, please do not install .NET Framework 3.5 SP1 Beta until a future Silverlight Tools update is made available.

Download Updated Blend 2.5 Preview
If you downloaded and installed a version of Blend 2.5 Preview prior to May 9th, please uninstall your existing version of Blend 2.5 Preview and install the updated version of from the following link:

Once you have the latest version of Blend 2.5 Preview installed, you can verify that you are running the latest version if your build number is 2.1.1113.0 by going to Help | About:

If you are running an earlier version of Expression Blend such as V1 or V2, please do not install the .NET Framework 3.5 SP1 Beta. Instead, please wait for the final release of .NET Framework 3.5 SP1 that will be compatible with all versions of Expression Blend.

Sending us Feedback
If you have any questions or encounter other issues while running Expression Blend 2.5 on .NET Framework 3.5 SP1 Beta, please let us know by posting on our forums.

Thanks,

Update (13 May 2008)
There’s been some confusion around the date of this blog post- the date that it’s picking up is when we originally discovered that we’d have to do an update to Blend coinciding with the 3.5 SP1 Beta and prepared the original draft of the blog post that we’d use to communicate the issue.

The publish date was completely accidental- just a byproduct of trying to coordinate releases. Sorry about the confusion, we really weren’t trying to be sneaky at all!

  • So we need the SP1 Beta to get ADO Entities to work properly with WCF & Silverlight serialization however if we do so we cannot edit our UI's anymore because Blend 2.5 gets disabled.

    However VS has no Silverlight designer..

    So how are we supposed to operate?

    I hate to harp but I think Blend needs fixing ASAP because whether I stay non-SP1 or go SP1 I am unable to continue either way.

  • Synced-

    For Silverlight development we strongly recommend not installed 3.5 SP1 Beta at this time- Blend will in fact work properly but the Visual Studio tools for Silverlight are not supported at all. Because the majority of Silverlight development requires VS support, we'd suggest waiting until the Silverlight tools for VS support it.

    Sorry!

    (and yes, we are working on it)

  • The first beta release of Service Pack 1 for both Visual Studio 2008 and .NET Framework 3.5 are available.

  • Hi,

    ScottGu said in his blog "There is a change in behavior in the .NET 3.5 SP1 beta that causes a problem with the shipping versions of Expression Blend.  This behavior change is being reverted for the final .NET 3.5 SP1 release, at which time all versions of Blend will have no problems running."

    I'm curious to know what kind of change broke Blend and why it should be reverted back instead of modifying the app. Thanks.

  • I would *really* appreciate the Silverlight tools to be updated for VS ASAP.

    There are issues fixed in this SP I specifically need for SL WCF development but since it breaks SL I can't install it. However without installing it WCF is broken without the sp1 fix.. So either way its broken.

    Thanks and take care.

  • As I mentioned in An old Visual Studio problem rears its ugly head back in February, I've been looking forward to SP1 for Visual Studio 2008 and NET Framework 3.5. Why? These are supposed to fix most of the problems I've been having with Visual Studio,

  • Please fix the Silverlight tool for VS ASAP so that it can work with 3.5 sp1 beta. Please...Please...Please!!!
