"Silverlight runtime" is the minimum requirement for viewing the Silverlight content in your browser.
For development, I will divide this into two subjects as below.
1. Minimum requirement for developing Silverlight
2. The best tools for developing Silverlight
1. Minimum requirement for developing Silverlight
- Software Requirement
There are currently two versions such as 1.0 and 2.0 Alpha for Silverlight. I guess, you won't need anything for developing Silverligth 1.0 project but you will need .NET framework 2.0 for compiling Silverlight 2.0 Alpha.
- Text Editor
You can write the codes with your favorite text editor. (Like you don't need VS for writing C# code.) In Silverlight, we use "managed code, XAML, Javascript, HTML" so those can be written with your favorite text editor.
2. The best tools for developing Silverlight 1.1 project
- Visual Studio 2008
- Silverlight 1.1 Alpha runtime
- Silverlight 1.1 Alpha SDK
- Silverlight 1.1 Alpha Tool for VS 2008
- Microsoft Expression Blend 2 December Preview (optional)
- ASP.NET 3.5 Extension (optional)
- Entity Framework and ADO.NET Data Service (Astoria) (optional)
You can use VS 2005 for developing Silverlight 1.0 but I suggest you to try Silverlight 1.1 (a.k.a 2.0). Because there will be huge differences between those versions. If you are using Silverlight 1.0, you will miss a lot of cool features of 2.0.
"Silverlight 1.1 Alpha SDK" will give you a few example of Silverlight 1.1 controls and etc..
"Silverlight 1.1 Alpha Tool for VS 2008 " will give you the silverlight project template and control/class library template. It will also give you the easiest way of integrating between ASP.NET and Silverlight.
"Microsoft Expression Blend 2 December Preview" - I used to use this tool for designing the Silverlight UI. There is no design view support for XAML so I used it as XAML Designer.
"ASP.NET 3.5 Extension" - I'm also new to this extension but Silverlight control from this extension is really helpful.
"Entity Framework and ADO.NET Data Service (Astoria)" - If you want to create data-driven silverlight application, you will need this. It allows you to use RESTful service in Silverlight application. I wrote a few posts about this in my blog.
Update:
Silverlight 2 beta1 is released.
Hope it helps.

Hi,
I'm trying to learn the WF architecture.
What I want to know is: Is there a way to access data stored in the workflow class?
I couldn't find a way to access this - even if I use the StateMachineWorkflowInstance-class
to access the CurrentState it's parents won't reflect the live-data (and of course if the workflow was persisted you cannot access the CurrentState at all).
So how can I get usefull information about the current state?
As an example let's say the worklfow handles a list with order and I want to get a list of all existing order ... the only hack I found was by implementing a event/method in a local service, invoking the event - handle the event and sending the information back via the CallExternalMethod.
So I handle the event using a ManualResetEvent to wait for the reply .... useless to say that this is .... not the way I want to do this in the future for simple data-requests.
And you can't just save the information in an external collection because the persistence-service won't see this stroage (only the data in the workflow).
Yes you can use a database to store the info and access the db - but I don't think this is good design.
Can somebody help?

Well - seems nobody got a clue ... no interesst in WF?

Interestingly when .NET 3.0 was called WinFX all the marketing buzz was about Avalon (WPF) and Indigo (WCF). When it got renamed as .NET 3.0 they then threw in WF and WCS. You could argue that WF was in a more complete state than WPF and WCF as regards tooling. Yet the latter two get all the attention and WF has been comparatively ignored! At work, for example, we're heavily into WPF and WCF but not WF - despite the fact that we could really make use of it. So I'm not surprised you aren't getting any answers here. Try asking in the WF forum in the MSDN forums. You're likely to get Microsofties popping up over there.

Well I guess I will try the managed groups.
It's somewhat sad that WF don't get much attention - I think it has great potential.

Yes, that's what I thought when I played with it briefly in the period before my current contract. I spent some time with the book Pro WF by Bruce Bukovics which I thought was well written and comprehensive.

Hi,
This behaviour is being caused by the default behaviour of the button ContentTemplate. You will need to define a new ContentTemplate for your button by using a ResourceDictionary and build the required elements as part of the new template. From the new template definition you will also be able to specify any mouse or keyboard related events that require animation.
See below for further information:
http://msdn2.microsoft.com/en-us/library/ms771597.aspx
Hope this helps...
Clean code is the key to happiness.

How can i clear out arrows in tree view in expanded elements?
Because shows arrows and text, but i wanna show only text....
Help, plz...

You will need to edit the control templates. This very easy in Blend because Blend returns back a copy of the current control template with one click of the mouse. There are also free videos on the Expression Blend site that walk you through editing a control template.
Here are two resources that will get you started.
http://www.codeproject.com/KB/WPF/CustomTreeViewLayout.aspx[^]
http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=2791439&SiteID=1[^]
FYI: The control template you need is nested inside the TreeViewItem and is actually a style for a ToggleButton.
Question: If you clear out the arrow, how will the user know that they can click a element and see more data. That is the purpose of the little, arrow.

With a bit of hack we were able to use command to return the current value of the target (as well as IsEnable), so we could nicely update color pickers, etc... on the control tool bar.
Now the problem is we use lots of command in our application (about 300).
And every time the user key one char in we do heavy processing as well (relayouting and repainting all visual information), and now that we have command, on top of the heavy text processing we've got all command updating (it's the behavior of the input manager to fire up an update of the command sources on key up).
So... since we moved to command we suffer huge performance problem due to the above reason.
Is there a way to disable command updating for a little while (while typing text) or.
In fact, ideally, I would like to disable only some command updating (whereas text command should still update...)
Any tip?

Lloyd,
I'll send Josh Smith an email about this question and see if he has some advice for you.
Do you have 300 commands all enabled all the time?
Does this problem only happen on one control or one form, or is it application wide?
What sort of application is this?

well, I'm not really working there anymore but the problem still haunt me!...
the application could be found there: http://www.novamind.com/[^]
All the button/controls on the ribbon are command source. There are lots of them. Most are enable all the time (although one could argue that invisible control should be disable, I'm not sure about what happen the ribbon control is a 3rd party, anyway some panel have a lot button).
What really slow down the app is text imput.
The main view is a legacy GDI+ control. The input text box in the view is a custom made text view (not a subclass of TextBoxBas, but of Control with custom text rendering via interop with Uniscribe, but with good perf, as it is able to paste 400k of text rich with the same perf as word).
But in NM3 it was already limit, big map slowing the application perceply (as not only we should layout the text, but move all the map's graphics and the autolayouting algorithm is time consuming)
Anyway on each key up, all command state is re-evaluate, and although each is relatively quick individually text processing was already putting us down (not only the text control shold do the layout, but we might need to move/relayout all graphics on the map as well...)
because of that NM4 using WPF (& commands) is slower than NM3 were that there was no such unnecessary work on key up...
is it a bit more clear now?!?

Lloyd,
Thanks for your response. I've sent Josh an email. Let's see where he takes this. I'm interested in his opinion too.
