Silverlight in the GAC?

I have tried to get a Silverlight web part to work in SharePoint, but each time I add the web part to the page, I get the SharePoint error message.  Here's the tutorial I just followed: http://blogs.msdn.com/andreww/archive/2009/03/12/silverlight-web-part-in-sharepoint.aspx

The only thing I think I'm missing is System.Web.Silverlight in the GAC, but I can't for the life of me figure out how to do that.  When I try to add it using .NET Configuration 1.1, I get an error messge that says: Unable to add the selected assembly.  The assembly must have a strong name (name, version, and public key).

I'm running Windows Server 2003 on a Virtual Machine.

Try using the gacutil:
http://msdn.microsoft.com/en-us/library/dkkx7f79(VS.71).aspx

Note that from the article you linked, that will need to be done on the sharepoint server, not your local machine (unless they are one in the same)

Thanks for the response!

I ran gacutil from the Visual Studio Command Prompt (couldn't get it to work from Run --> cmd) and it said it was successfully added.  However, i'm still getting the same error in SharePoint when I try to add the web part, and the .NET Configuration still doesn't show it in the Assembly Cache (I did refresh), and I still get the same error when I try to add it in there.  I am doing all of this on the server running SharePoint.

Found a website to set web.config so SharePoint can give more meaningful error messages, and this is the error I'm getting:

Not sure of your setup , but are you sure .NET configuration 1.1 is the one you should be using ?
I think the one for version 2 that comes with the SDK is the one to use if you are running versions 2.0 or 3.0 & 3.5 of the .NET framewok
http://www.microsoft.com/downloads/details.aspx?FamilyID=fe6f2099-b7b4-4f47-a244-c96d69c35dec&displaylang=en
you can also try to drag & drop the assembly directly to the GAC folder on the file system C:\Windows\Assembly

Good call, Admin3k.  Opened up .NET Configuration 2.0 and the dll is indeed in the GAC.  However, I'm still getting the error posted above.

Help?

Thanks!

Ugh...I found this link: http://blogs.msdn.com/fooshen/archive/2008/10/18/performance-point-server-2007-and-ajax-on-sharepoint.aspx

However, I can't get to the PPS and PPM web.config files.  Should I just install AJAX?

Mohamed OsamaSenior IT ConsultantCommented:
Shouldn't harm & could possibly solve it if some older code is involved.

Oddly, the web page shared a part from PerformancePoint dashboard.  Taking that out (in addition to adding the lines below to the main web.config as well as the web.configs in PPSMonitoring - Preview and PPSMonitoring - Web Service) solved the problem.

Thanks!
