SharePoint 2010 and ASHX Handler

Question

I'm trying to get a webpart deployed and using a Silverlight webpart with an upload control inside. I am however, receiving the following error in the application log when I access my ashx.

Exception information: 
Exception type: HttpParseException 
Exception message: Could not create type 'FileUploadSP.UploadHandler'.

I've got an UploadHandler.cs file with the following code:

namespace FileUploadSP
{
public class UploadHandler : RadUploadHandler 
{
    public override void ProcessStream()
    {
        base.ProcessStream();

        if (this.IsFinalFileRequest())
        {
            string filename = this.Request.Form["RadUAG_fileName"];
            string fullPath = @"C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\TEMPLATE\LAYOUTS\FileUploadSP\FileTemp\";
            SPContext.Current.Web.AllowUnsafeUpdates = true;
            FileStream fs = new FileStream(fullPath + filename, FileMode.Open);
            SPContext.Current.Web.Files.Add("/UploadLibrary/" + filename, fs, true);
            fs.Close();
            File.Delete(fullPath + filename);
        }

    }
}

}

And I have the following in my .ashx file:

<%@ Assembly Name="Microsoft.SharePoint, Version=14.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c" %> <%@ Assembly Name="FileUploadSP, Version=1.0.0.0, Culture=neutral, PublicKeyToken=7c8e2c3ef53023ee" %> <%@ WebHandler Language="C#" Class="FileUploadSP.UploadHandler" %>

I cannot get the .ashx to work as I expected to. What am I missing?

Thanks!

Check your assembly is in the web.config safe list, and has been deployed to the GAC, with an iis reset.

Ashx can be blocked (and unblocked in central admin), but I guess from your error this is not the case.
