Download Expression Blend Preview for .NET 4

Today at PDC, we made a few announcements that would be of interest to you! First, Scott Guthrie announced the availability of the Silverlight 4 Beta. This version of Silverlight contains some cool new features that many of you have asked for, so read the What’s New document to get an overview of some of the new features.

To coincide with the release of Silverlight 4 Beta today and the release of Visual Studio 2010 Beta 2 a short while ago, we are making a version of Expression Blend available that allows you to work with .NET 4 and Silverlight 4 based projects.

Download it from the following location now:

This release of Expression Blend works well alongside Expression Blend 3, so you can continue to work on your WPF 3.5 and Silverlight 3 based projects at the same time.

As always, we love to hear from you. Please feel free to comment below or use our forums here.

    While it wouldn’t help Microsoft’s bottom line, it would surely make life a lot easier for users if new versions of WPF and Silverlight could be accommodated by add-ins for Blend rather than requiring a complete new version (which doesn’t preclude having a new version to provide additional functionality for Blend itself, it’s just a matter of keeping the platform costs within reason (because we can’t all afford MSDN subsccriptions)

    Does the Expression Blend Preview for .NET 4 (and VS 2010 Beta)  also work side-by-side with the following environment:

    Expression Blend 2 SP1 and VS 2008 with .NET Framework 3.5 SP1?

    I was just thinking about buying Expression 3, but just like when I was about to buy Expression 2, I may have to hold on to my wallet again.

    Something needs to be done to help the independent developer, doesn’t it?  I have never sprung for Expression because it moves too fast.  I am instead stuck in XAML land, and I feel my ability to design is never as productive as if I had Blend.

    I can’t afford an MSDN Premium subscription and I barely can afford the MSDN Professional (which doesn’t include Blend).

    I know at MSFT the "designer" and "developer" roles are neatly separated, but I think for smaller teams and companies this just isn’t the case.

    Confused as to what to consider spending money on again…

    Agree with above comments. Although new version every year at MIX is great, its lifecycle is way too short for our wallets. Alternate versions should be free upgradesm to allow a decent 2 year life cycle. Windows, Office and Visual Studio have at least a 2-3 year lifecycle.

    Silverlaw – Blend Preview for .NET 4 should work side-by-side with Blend 2 SP1. (answer courtesy of Pete Blois (

    Kevin / CGomez / expr – thanks for the feedback. I’ll try to address this issue in the future when appropriate.



  6. Boyd says:

    yeah, this is a problem now!

    But I think this is one of the last "fast" versions. WPF and .net were in a rapid development last years, but now they are on a good level and they have reached a high level of functionality and productivity.

    Small business worried about cost should consider the Microsoft Action Pack program ( ), or MS Empower ( Individuals should think about taking a class locally so they can get the Academic Pricing.

  8. Pat S says:

    It’s not a question of working side by side but requiring ISVs to buy a version every year. Imagine if something like Office or Visual Studio came out every year.

  9. I think Source Control should be integrated into the product for following versions.

  10. Bernie says:

    I fully agree what’s been said ealier. How can we be expected to pay for a whole new version of Expression Studio every 6 months. I bought Expression Studio 3 and my product hasn’t even been rolled out yet and I’ll have to consider upgrading already. This is rediculous!

    I suggest MS find a way to install support for new versions of silverlight/wpf straight into existing versions of Blend. I’m already sitting with an unusable Blend V2 and soon Blend V3 aswell.

    Expecting people to pay for upgrades this frequently will definitely harm the product in the long run and put off developers. I’m already starting to regret going down this path if this is how things are going to carry on in future.

  11. Mystery Man says:

    Lol, just torrent the new expression blend. Yes it is illegal but costs nothing and you get what you want in return 😉

  12. Michael says:

    @Mystery Man

    So, you steal others software, just to sell your own software! WTF

  13. David says:

    hey guys, im using Blend preview for .net 4 for about a week until a while ago when i open it, it shows a dialog said "Thank you for evaluating the product …blah blah… please enter a valid product key". There’s a link "Get a free Beta product key online" but it just open the "How to Buy" page in Expression website….

    where can i get a free beta key?

  14. Siddhartha Ghosal says:

    I could not find Sketch Flow Application templates in Blend 4. Can anyone help me find it?

  15. ehuna says:

    Any idea when a Blend preview that works with Visual Studio 2010 RC will be available?  It’s the one thing that stopping me from upgrading our projects – since we have graphics designers that use Blend 3.

  16. CGomez says:

    Just heard the MIX10 keynote announce that Blend 4 would be a free upgrade (of some kind) for Expression Blend 3 owners.  This is great news.  It’s too bad this wasn’t announced much sooner, as my previous comment from November shows I have gone without Blend for months because I knew Silverlight and Blend 4 were coming.

    Nevertheless, this is good news for current Blend owners and I applaud MSFT for helping their developers move forward at the same lightning fast pace Silverlight is moving at.

  17. new-comer says:

    after reading the comments i started asking myself – should i even start to learn using this product ? why on earth would i be interested in learning proprietary products and pollute my mind with proprietary owned caged knowledge ?

  18. Ganwar says:

    Is Microsoft Expression Blend Software Development Kit (SDK) for .NET 4 free to download ?
