Re: Re: Re: How to return html page from WCF with WebHttpBinding

Actually, this may be a better example: http://msdn.microsoft.com/en-us/library/cc681221.aspx

I've modified the msdn example above to support .html and .xap files:

With this your Silverlight App can be accessed via a URL such as: http://localhost:8000/Service/Files/LoadXap.html 

 

HTML snippet: 

    <div id="silverlightControlHost">
		<object data="data:application/x-silverlight," type="application/x-silverlight-2-b2" width="100%" height="100%">
			<param name="source" value="YourSilverlightAppHere.xap"/>
			<param name="onerror" value="onSilverlightError" />
			<param name="background" value="white" />
		</object>
    </div>

  

WCF Code: 

    // define the service contract
    [ServiceContract]
    public interface IFileHost
    {
        [OperationContract, WebGet(UriTemplate = "Files/{filename}")]
        Stream Files(string filename);
    }

    // implement the service contract
    public class Service : IFileHost
    {

        public Stream Files(string filename)
        {
            Stream stream = (Stream)new FileStream(filename, FileMode.Open);

            //Set the correct context type for the file requested.
            int extIndex = filename.LastIndexOf(".");
            string extension = filename.Substring(extIndex, filename.Length - extIndex);
            switch(extension)
            {
                case ".html":
                case ".htm":
                    WebOperationContext.Current.OutgoingResponse.ContentType = "text/html";
                    break;
                case ".xap":
                    WebOperationContext.Current.OutgoingResponse.ContentType = "application/x-silverlight-2-b2";
                    break;
                default:
                    throw(new ApplicationException("File type not supported"));
            }

            return stream;
        }

    }

    class Program
    {
        static void Main(string[] args)
        {
            string baseAddress = "http://" + Environment.MachineName + ":8000/Service";
            ServiceHost host = new ServiceHost(typeof(Service), new Uri(baseAddress));
            host.AddServiceEndpoint(typeof(IFileHost), new WebHttpBinding(), "").Behaviors.Add(new WebHttpBehavior());
            host.Open();
            Console.WriteLine("Service is running");
            Console.Write("Press ENTER to close the host");
            Console.ReadLine();
            host.Close();

        }
    }
