Where to get the tools:

http://silverlight.net/GetStarted/

 

All tutorials/HOLs/Samples need Silverlight 2 Beta 1 Runtime, Visual Studio 2008 Tools and Silverlight 2 Beta 1 SDK installed.  Expression Blend 2.5 is recommended.

  

When you try to access the SDK help from within VS 2008, the Silverlight help is not automatically integrated.  It is pretty straight-forward to do by following these steps:

 

1.       Open Visual Studio (you might have to open VS as an administrator).

2.       In the Help menu, choose Index. Microsoft Document Explorer displays.

3.       In the Filtered by: drop-down, choose to (unfiltered).

4.       In the Look for field, type Collection Manager.

5.       Below the Collection Manager heading, double click Help.

6.       Below the Collections available for inclusion in VSCC heading, check Microsoft Silverlight 2 SDK Documentation.

7.       Click Update VSCC.

 

You will be prompted to close all open instances of Visual Studio.  Follow steps 1 through 3 above. Click the Contents Tab and look for Microsoft Silverlight 2 SDK.  It will take only a few minutes to update the collection and merge in the Silverlight help files.
