ZAM 3D / Expression Integration White Paper  – Brief overview of how to integrate ZAM 3D XAML in Expression Interactive Designer projects.NEW ZAM 3D to Expression Wokflow Page 
The other way to create a new element is to select the element type in the Library palette and then draw it onto the artboard. When drawing, the parenting rules are different. If a container element is selected and the mouse down gesture of the draw happens inside its bounds, then the selected container becomes the parent. Otherwise the activated element becomes the parent.
That covers how new elements are parented. But what about dragging an existing element to another parent? In Windows Forms, when you drag an element to a new location the design surface re-parents the element inside the front-most container at the mouse pointer. Expression Interactive Designer doesn't assume that you wish to re-parent an element when you drag it to a new position. This is mainly due to (partially) transparent elements. I may want to drag an element from one cell of a Grid to another cell which happens to be behind part of a Canvas with an opacity mask. In this case I don't want to have my element re-parented just because the Canvas is in front of the Grid, and EID leaves the element under its current parent (at the new position) unless I indicate otherwise. Whenever I drag an element into the boundary of a candidate parent container, EID offers the tip: Alt-drag to place into [container_type]. Only if I hold down ALT while completing the drag is the element re-parented.

Microsoft Expression Interactive Designer (EID) is largely about creating and editing trees of user-interface elements. When you use the double-click gesture in the Library palette (View > Library) to create a new element, Interactive Designer needs to know into which container in the tree to put the new element. So we have this idea of the 'active' or 'activated' container which refers to an existing container which will become the parent of the new element. Only one container in the tree can be activated at any time. By the way, I use the term 'activated' because the container in question is in a particular state, ready to receive the new element. 'Active' implies the container is somehow going to do something whereas in fact its state is passive. Either term is ok to use and they refer to the same idea.
So, how do you set a container to be activated and how do you identify the currently activated container? I would recommend that you go to the element tree (in the Timeline palette - View > Timeline) and expand the tree until you find the container you want to activate. Then double-click the container and note that it now appears in both the element tree and on the artboard with a yellow highlighted border. It's the highlighted border which shows which container is activated.
Now, when you double-click an element type from the Library palette (View > Library), EID will create the new element and nest it as a child of the activated container. If the activated container is one which may have only one child, and that container already has a child, then your double-click-to-create gesture will replace the previous child (and all its children, if any). This is sometimes what you want, other times it may be an indication that the activated container was not the one you intended. Always check for the yellow highlighted border before double-clicking from the Library palette.
The other way to create a new element is to select the element type in the Library palette and then draw it onto the artboard. EID will place the new element as a child of the container most appropriate to the location in which you are drawing.

In case you were wondering what we look like, here's a cheerful photograph taken this evening when the Expression team gathered together to relax and share a drink and mark the occasion of the two CTPs being released today. As is natural with a large team, not everyone could be present for the photograph, and regrettably there are one or two notable Expression-ists (pardon the terrible pun) whom we weren't lucky enough to capture on CCD. Maybe we'll correct that in the future.
ZAM 3D ™ from Electric Rain is a new 3D XAML Tool for Microsoft Windows Vista application development, and a CTP is available for download .
ZAM 3D fits into the designer-side workflow by complementing Microsoft Expression Interactive Designer. The idea is that a designer uses ZAM 3D to easily create 3D interface elements, models, controls, styles or layouts. Then the designer exports the 3D assets to XAML markup with a single click without any need to write, or even understand, the complex markup that goes into building a WPF 3D scene. Now the 3D assets are easily added to an Expression Interactive Designer project using the Project > Add Item... command.
You can see some stunning examples of ZAM 3D assets  in use in Windows Vista applications on Electric Rain's website.
Today we are also delighted to announce the availability of a new preview version of Expression Graphic Designer. This preview version is the January 2006 Community Technology Preview 
We would like to thank you for your enthusiastic support regarding our professional graphic design application, Microsoft Expression Graphic Designer (formerly code-named "Acrylic"). We look forward to your continued feedback.
Please note that you must complete a product registration to receive this download.
We thought it was worth calling out this item as it may be an issue some of you encounter.
If you are trying to test build a project (Project | Test Project) immediately after installing WinFX and Expression Interactive Designer, but Expression Interactive Designer was never launched before, your build attempt might fail with the following message: “Error MC1000: Unknown build error”. If this occurs, you will need to close Expression Interactive Designer and launch it again.
Quite painless, hopefully, but worth knowing.
Originally it was the rather witty 'Flickr Browsr', although now an 'e' has crept back in to 'Browser'!
The Flicker Browser sample application which features in the recent Channel 9 video  is available for download from Amir Khella's blog  so please feel free to check it out.
You will need to get a free Flickr API key of your own and paste it in the file called FlickrKey.txt in order for the sample to run correctly. You can get a key from http://www.flickr.com/services/api/key.gne.
Thanks very much to Amir Khella (Program Manager on Expression) and Peter Blois (Software Design Engineer on Expression) for collaborating to produce this sample and showing great developer-designer workflow in the process.
Today we are delighted to announce the availability of a preview version of Expression Interactive Designer. This preview version is the January 2006 Community Technology Preview and you can download it at the following URL:
We have compiled a set of sample applications and tutorials specifically for this CTP and you can see the gallery of these samples over on the right of the blog. Look for the box titled 'Article Categories' and then click Samples and Tutorials Gallery - EID Jan 06 CTP to take you to the gallery (or just click the link given above).
In the same 'Article Categories' box is a link to the Readme file for the Jan 06 CTP which contains important late-breaking news and known issues - Readme File - EID Jan 06 CTP.
There are lots more resources about Expression on the Microsoft Expression web site.
If you enjoyed the previous Channel 9 video featuring the Expression Interactive Designer team then you'll want to check out the new video Robert Scoble hosted and posted today at the link below:
Hi, we’re glad to have you visit the Expression team’s blog - we hope you’ll like the resources and information you find here and we hope you’ll return often to see what’s new.
This introductory post will talk about what the Expression family of products is. It will also talk about the blog itself, what it’s for, and what kinds of things you can expect to find here over the coming months.
So, first, what is Expression? Microsoft Expression is a suite consisting of three products each intended for use mainly by the professional designer community. Expression Graphic Designer is a visual arts package equally at home with vector or with bitmap graphics. Expression Interactive Designer gives interaction designers the environment in which to build Windows applications for the Windows Presentation Foundation platform - in other words, to build the new Vista-wave generation of Windows user experiences. Expression Web Designer is the product which offers all the tools you’ll need to produce high-quality, standards-based Web sites.
For lots more information, videos and downloads about Expression, please see the Microsoft Expression product website.
Now, about the blog. The blog’s scope embraces all three Expression products so there will be a great diversity of resources to be found here, all brought together with the intention of being of interest to designers and to the designer sensibility. Although we expect professional designers to be our main audience, if you’re a design dilettante or a Windows or Web developer, please feel free to dive in and experience and enjoy Expression too!
In the Article Categories section of the blog, you will find up-to-date directories of sample applications, tutorials and visual artwork. As the names indicate, these samples are targeted at particular pre-release or Community Technology Preview (CTP) versions of the Expression products.
In the same section there are also articles which contain the ‘readme’ files for particular pre-release or CTP versions of the Expression products.
The types of blog posts you can expect to see include these:
