There is no way to do that. The xap contains all the assemblies you reference. It needs to be there otherwise your application would not run. A Silverlight application runs inside the Silverlight plugin on the clients machine. All assemblies required by the application must, therefore, be downloaded to the client machine. There are ways to break things into multiple Xap files so it only downloads what it needs when it needs it, but that is a pure (advanced) Silverlight discussion which you could try to search MSDN or other Silverlight sites for.

HI Foram
you can do it by putting the silverPDF.dll in clientbin folder and call it when needed like this

AssemblyPart apSilverPDF;
System.IO.Stream PDFStream;

        /// <summary>
        /// Load the silverPDF library if it hasn't been loaded already
        /// or use the library if already loaded        
        /// </summary>
        public void LoadPDFLibraryAndSaveFile()
        {
            SaveFileDialog savePDF = new SaveFileDialog();
            savePDF.Filter = "PDF file format|*.pdf";
            savePDF.DefaultExt = ".pdf";
            if (savePDF.ShowDialog() == true)
            {
                //catch the error if the user tries to save over a file that is currently open
                try
                {
                    PDFStream = savePDF.OpenFile();
                    //if silverPDF library is not loaded already, load it
                    if (apSilverPDF == null)
                    {
                        LoadPDFLibrary();
                    }
                    else
                    {
                        //if the library is loaded, just save the PDF file
                        SavePDF();
                    }
                }
                catch (IOException ioe)
                {
                    //tell the user the file is open
                    MessageBox.Show("Selected PDF file is open. Close the file and try again!", "Open File Error", MessageBoxButton.OK);
                }
            }
        }

        /// <summary>
        /// Send a request to load the silverPDF library dynamically
        /// </summary>
        private void LoadPDFLibrary()
        {
            WebClient client = new WebClient();
            client.OpenReadCompleted += new OpenReadCompletedEventHandler(client_OpenReadCompleted);
            Uri _uri = new Uri("silverPDF.dll", UriKind.Relative);
            client.OpenReadAsync(new Uri("silverPDF.dll", UriKind.Relative));
        }

        /// <summary>
        /// Load the library and use it to create the PDF
        /// </summary>
        /// <param name="sender"></param>
        /// <param name="e"></param>
        private void client_OpenReadCompleted(object sender, OpenReadCompletedEventArgs e)
        {
            if ((e.Error == null) && (e.Cancelled == false))
            {
                apSilverPDF = new AssemblyPart();
                apSilverPDF.Load(e.Result);

                SavePDF();
            }
            else
            {
                MessageBox.Show("There was a problem loading PDF Library", "PDF Library Loading Error", MessageBoxButton.OK);
            }
        }

tell me if it works
