Question

i have a problem with Firefox and Silverlight. I have a silverlight application (with version-number 1.0.0.0) on my website. Now I have modified the silverlight application(version-number is now 1.0.0.1) and replaced the old file on the server with my new application.

The Internet Explore loads the new application correctly. But unfortunally the Firefox 4 still loads the old Silverlight application.

Is there a trick to fix this issue or have i to rename the xap file on every update?

Than You

May be Firefox cached that xap and load cahced one.
If you wont do load xap every time user opens the page, then replace

 <param name="source" value="ClientBin/YourXapName.xap" />

with this one

        <%
            string orgSourceValue = @"ClientBin/YourXapName.xap";
            string param;    
            if (System.Diagnostics.Debugger.IsAttached)    
                param = "<param name=\"source\" value=\"" + orgSourceValue + "\" />";
            else
            {
                string xappath = HttpContext.Current.Server.MapPath(@"") + @"\" + orgSourceValue;
                DateTime xapCreationDate = System.IO.File.GetLastWriteTime(xappath);        
                param = "<param name=\"source\" value=\"" + orgSourceValue + "?ignore=" + xapCreationDate.ToString() + "\" />";
            }
            Response.Write(param);
         %>
