I am missing the above namespaces.  I just installed Silverlight sdk 2.0 Beta 1, Silverlight tools alpha for VS 2008 (not beta), and Silverlight runtime 2.0.

Previous post said to install 1.1 runtime.  2.0 runtime removed 1.1 runtime on install.

I can't be the first??

If you're developing for Silverlight 2, you need to install the beta tools.  Silverlight 1.1 is deprecated and not supported by the SL 2 features.

Thanks, I uninstalled the alpha tools and tried to install the beta tools and got this error:

morgan-hill:

(how do I know if this is installed and enabled?  I do see it in add/remove prgrams how is it enabled?)

It's okay if you see it in Add/Remove Program.

morgan-hill:

Nope, when I installed 2.0 it unstalled 1.0)

Okay.

morgan-hill:

Nope 2.0 is installed)

*** here is important thing. Please uninstall Silverlight 2 SDK.  This is a known issue.

morgan-hill:

couldn't find it installed

You can check "updates" checkedbox in Add/Remove.
