I'm using blend  2.0 and VS2008 with the silverlight tools Beta 1.  I've been looking for quite some time and I can't figure out how to:

• Create some kind of user control in blend.
• Import that as a new item into an existing web application project (that I could reference with a silverlight control).
• Have some code behind the user control.

>> Create something in Blend and use in Visual Studio?

You can open VS 2008 from Blend.

- Right click on XAML file.

- Choose "Edit in Visual Studio" 

You can also open Blend from VS 2008.

- There is one option called "Open in Blend" in Right-click menu of Solution Explorer.

- I don't see either option (in blend or VS2008).  Anything I can try other than simply uninstalling/reinstalling?

- If I have an existing web application project, how can I create a new user control for that project (the option isn't available unless I'm in a silverlight project)?
 

You may need Blend 2.5 to work with sivlerlight 2 project:

Blend 2.5 allows me to cross edit from blend to VS2008, but my question remains.  How do I create a user control (in VS or in blend) that I can visually edit with blend but still use in an existing web application VS2008 project?  Do I have to create a new silverlight application in VS, add a user control, then import that into my existing web application?

Neither blend nor VS2008 web application projects give me the option to create a user control.  Can I just wrap some existing XAML in a UserControl element?  Would that still be editable in blend?

In your VS2008 silverlight project, add an UserControl (or find an existing one). Right Click the XAML file and Click "Open In Express Blend...". It will take you to the Blend. After you are done you just save it, and come back to VS2008 you should see the XAML file been updated.

This is what I have been trying to ask.  I need to add silverlight user controls to an existing VS2008 web application project. 

You can not add a silverlight control to a Web application project. You need to add it to a Silverlight project. Then you can add Silverlight link to your Web Project.

The Web project is running on the Server under ASP.Net service. The silverlight code is running on the Client side in the browser. That's why you can not mix them up.

• Add a silverlight link to my web project?  How do I do that?
• I can't mix client side and server side code?  All web developers have been doing that since the beginning... 

Here is the quick start for Silverlight. Follow the instruction you should be able to create your silverlight project and Web project.
 

http://silverlight.net/quickstarts/managed.aspx 

You can use Server side code to build pages, and put client side code on your page. The client side code will be running on the client side like javascript. But you never compile the server side code and client side code into one DLL. That's I meant you can not mix them up.

When we talk about silverlight 2 development most people here are taking the advantage of managed code silverlight 2 provide to write their silverlight application in C# or VB.  So the code will be compiled into a .XAP file. When you create a silverlight link to your Web project the XAP file will be copied to your web project ClientBin folder. The code for your web project running on the Server will still be in the Bin folder. The Xap file will be downloaded to the client side when user hit the page and be running there.

The code in silverlight project can only access the Silverlight runtime DLL which is a sub set of the WPF and common .Net Framework. But the server side code in your Web Project can access the full set of the .Net Framework.

Thanks.  Was still hung up on the option "link this silverlight control into an existing web site" which is disabled when creating a new silverlight application directly.  One must add a new silverlight application project to an existing web project in order to enable that option.
