Hello:<br />

I am trying to run a silverlight application on a Windows 2003 server. I am getting the following error in Visual Studio 2010.<br />
<br />
Could not load file or assembly 'System.Windows.Controls.D<wbr />ata.DataFo<wbr />rm.Toolkit<wbr />, Version=4.0.5.0, Culture=neutral, PublicKeyToken=31bf3856ad3<wbr />64e35' or one of its dependencies. Operation is not supported. (Exception from HRESULT: 0x80131515)<br />
<br />
I installed both Silverlight 4 and 5 toolkits on the server and add the mine types in IIS:<br />
<br />
.xaml &nbsp;application/xaml+xml<br />
.xap &nbsp; application/x-silverlight-<wbr />app<br />
<br />
When I run the silverlight app on my local machine it runs fine and there are no issues.<br />

Silverlight on Windows 2003 Server

Windows Server 2003 was based on Windows XP and was released in four editions: Web, Standard, Enterprise and Datacenter. It also had derivative versions for clusters, storage and Microsoft’s Small Business Server. Important upgrades included integrating Internet Information Services (IIS), improvements to Active Directory (AD) and Group Policy (GP), and the migration to Automated System Recovery (ASR).

Windows Server 2003

Windows Communication Foundation (WCF) is a tool used to implement and deploy a service-oriented architecture (SOA) to support distributed computing where services have remote consumers. It features a runtime and a set of APIs in the .NET Framework for building connected, service-oriented applications. Services typically have a WSDL interface (Web Services Description Language) that any WCF client can use to consume the service, regardless of which platform the service is hosted on. WCF implements many advanced Web services (WS) standards such as WS-Addressing, WS-ReliableMessaging, WS-Security, RSS Syndication Services, WS-Discovery, routing and better support for REST services.

The successor to Active Server Pages, ASP.NET websites utilize the .NET framework to produce dynamic, data and content-driven web applications and services. ASP.NET code can be written using any .NET supported language. As of 2009, ASP.NET can also apply the Model-View-Controller (MVC) pattern to web applications
