How make faster asp.net websites in ASP.NET 4.5 with EF 6

Hi Guys,

I was able to successfully create a responsive and very fast website with EF6 and ASP.NET 4.5. Here is how i was able to do it successfully.

1. Create a basepage which all the webforms inherits and add the following code in the constructor of the basepage

a. you need to install a nuget package

PM> Install-Package EFInteractiveViews

b. Then add below code in your constructor of basepage class
public BasePage()
        {
            try
            {
                using (var ctx = new LPUOnlineEntities())
                {
                    InteractiveViews.SetViewCacheFactory(ctx, new SqlServerViewCacheFactory

(ctx.Database.Connection.ConnectionString));
                }
            }
            catch (Exception ex)
            {

            }
        }


2. Enable ViewState Compression

a. Create two methods in your basepage class
protected override object LoadPageStateFromPersistenceMedium()
        {
            string viewState = Request.Form["__VSTATE"];
            byte[] bytes = Convert.FromBase64String(viewState);
            bytes = Compressor.Decompress(bytes);
            LosFormatter formatter = new LosFormatter();
            return formatter.Deserialize(Convert.ToBase64String(bytes));
        }

        protected override void SavePageStateToPersistenceMedium(object viewState)
        {
            LosFormatter formatter = new LosFormatter();
            StringWriter writer = new StringWriter();
            formatter.Serialize(writer, viewState);
            string viewStateString = writer.ToString();
            byte[] bytes = Convert.FromBase64String(viewStateString);
            bytes = Compressor.Compress(bytes);
            //ClientScript.RegisterHiddenField("__VSTATE", Convert.ToBase64String(bytes));
            ScriptManager.RegisterHiddenField(this, "__VSTATE", Convert.ToBase64String(bytes));
        }

b. A class which compresses the data

using System.IO;
using System.IO.Compression;

public static class Compressor
{

    public static byte[] Compress(byte[] data)
    {
        MemoryStream output = new MemoryStream();
        GZipStream gzip = new GZipStream(output,
                          CompressionMode.Compress, true);
        gzip.Write(data, 0, data.Length);
        gzip.Close();
        return output.ToArray();
    }

    public static byte[] Decompress(byte[] data)
    {
        MemoryStream input = new MemoryStream();
        input.Write(data, 0, data.Length);
        input.Position = 0;
        GZipStream gzip = new GZipStream(input,
                          CompressionMode.Decompress, true);
        MemoryStream output = new MemoryStream();
        byte[] buff = new byte[64];
        int read = -1;
        read = gzip.Read(buff, 0, buff.Length);
        while (read > 0)
        {
            output.Write(buff, 0, read);
            read = gzip.Read(buff, 0, buff.Length);
        }
        gzip.Close();
        return output.ToArray();
    }
}



3. Combine your scripts into 1

a. Give this nuget command

Install - Package Microsoft.AspNet.Web.Optimization

b. In application_strat in global.asax, Add the below code

System.Web.Optimization.BundleTable.Bundles.Add(new System.Web.Optimization.ScriptBundle("~/bundle/js")
              .Include("~/Scripts/*.js"));
        System.Web.Optimization.BundleTable.Bundles.Add(new System.Web.Optimization.ScriptBundle("~/bundle/css")
             .Include("~/Styles/*.css"));

c. Remove all the references of javascript from the master page or web page and replace it with

<%: System.Web.Optimization.Scripts.Render("~/bundle/js") %>
     <%: System.Web.Optimization.Styles.Render("~/bundle/css") %>

d. under system.web add the tag in web.config file

<system.web>
    <compilation debug="false" />
</system.web>

4. Enable Compression on IIS from web.config under <system.webServer>.

    <httpCompression directory="%SystemDrive%\inetpub\temp\IIS Temporary Compressed Files">
      <scheme name="gzip" dll="%Windir%\system32\inetsrv\gzip.dll" />
      <dynamicTypes>
        <add mimeType="text/*" enabled="true" />
        <add mimeType="message/*" enabled="true" />
        <add mimeType="application/javascript" enabled="true" />
        <add mimeType="*/*" enabled="false" />
      </dynamicTypes>
      <staticTypes>
        <add mimeType="text/*" enabled="true" />
        <add mimeType="message/*" enabled="true" />
        <add mimeType="application/javascript" enabled="true" />
        <add mimeType="*/*" enabled="false" />
      </staticTypes>
    </httpCompression>

5. To compress sessions add the following line in your web.config's <system.web> section

<sessionState compressionEnabled="true"></sessionState>

6. To compress your scripts add the following lines in your web.config

<system.web.extensions>
    <scripting>
      <scriptResourceHandler enableCompression="true" enableCaching="true" />
    </scripting>

  </system.web.extensions>

7. To reduce number of webresource.axd and scriptresource.axd request, Replace your ScriptManager with below code

<asp:ScriptManager ID="ScriptManager1" ScriptMode="Release" runat="server">
                <CompositeScript>
                    <Scripts>
                        <asp:ScriptReference Name="MicrosoftAjax.js" />
                        <asp:ScriptReference Name="MicrosoftAjaxWebForms.js" />
                    </Scripts>
                </CompositeScript>
            </asp:ScriptManager>
