We are supposed to get Windows AppFabric Cache real soon, but till than form time to time we need to synchronize content cached inside our Web roles. SqlDependency is one way, but it cannot solve all problems (especialy those that are not based on SQL data). So to help with the matter I wrote AzureStorageCacheDependency that uses Azure storage to know when data is outdated and cache shloul be cleared. If anyone is in need of something similar, here it goes:

public class AzureStorageCacheDependency : System.Web.Caching.CacheDependency
    {
        private System.Threading.Timer _timer;
        private int _poolTime;
        private CloudBlob _blob;
        private string _key;

        public AzureStorageCacheDependency(string connectionString, string conteinerAddress, string blobAddress, int poolTime = 5000)
        {
            _poolTime = poolTime;
            using (AzureContext azureContext = new AzureContext(true))
            {
                var storageAccount = CloudStorageAccount.Parse(connectionString);
                CloudBlobClient blobStorage = storageAccount.CreateCloudBlobClient();
                CloudBlobContainer container = blobStorage.GetContainerReference(conteinerAddress.ToLower());
                container.CreateIfNotExist();
                _blob = container.GetBlockBlobReference(blobAddress.ToLower());
                if (!Exists(_blob))
                {
                    Reset();
                }
                else
                {
                    _key = _blob.DownloadText();
                }
            }
            _timer = new Timer(new System.Threading.TimerCallback(CheckDependencyCallback), this, 0, _poolTime);
        }



        public void Reset()
        {
            _key = Guid.NewGuid().ToString();
            _blob.UploadText(_key);
        }

        private void CheckDependencyCallback(object sender)
        {
                if (!Exists(_blob) || _key != _blob.DownloadText())
                {
                    NotifyDependencyChanged(this, EventArgs.Empty);
                    _timer.Dispose();
                }
        }

        public static bool Exists(CloudBlob blob)
        {
            try
            {
                blob.FetchAttributes();
                return true;
            }
            catch (StorageClientException e)
            {
                if (e.ErrorCode == StorageErrorCode.ResourceNotFound)
                {
                    return false;
                }
                else

            if (forceSettingContextToNull)
            {
                _oldHttpContext = HttpContext.Current;
                HttpContext.Current = null;

        ~AzureContext()

            Dispose(false);
        }
    }

From time to time, we need to selectively redirect the browser to another location as a 
result of an AJAX action. Just returning RedirectResult won’t do the trick (even if we 
are used to similar functionality in ASP.NET AJAX in combination with WebForms ). Here 
is a very simple RedirectResult thet will be appropriate in those scenarios:

    public class AjaxRedirectResult : RedirectResult
    {
        public AjaxRedirectResult(string url): base(url){}
        public override void ExecuteResult(ControllerContext context)
        {
            if (context.RequestContext.HttpContext.Request.IsAjaxRequest())
            {
                JavaScriptResult result = new JavaScriptResult()
                {
                    Script = String.Format("window.location='{0}';",
			UrlHelper.GenerateContentUrl(Url, context.HttpContext)) 
                };
                result.ExecuteResult(context);
            }
            else
                base.ExecuteResult(context);
        }
    }

Some time ago I wrote how to deploy multitenant application to the Cloud. The process was tricky at best. With new Windows Azure SDK 1.3 things just got a lot simpler and I absolutely love it. The feature is called Full IIS and allows your web roles to access the full range of web server features that are available in on-premise IIS installations. However if you choose to use them, there are a few differences from the classic Azure Hosted Web Core (HWC) model.

First you need to tell Windows Azure SDK to use Full IIS instead of HWC and you do this by adding a valid <Sites> section to your ServiceDefinition.csdef  file.  By default Visual Studio will create HWC model definition like this:

    <Sites>
      <Site name="Web">
        <Bindings>
          <Binding name="Endpoint1" endpointName="Endpoint1" />
        </Bindings>
      </Site>
    </Sites>

You can easily customize it to define multiple web sites, or virtual apps (virtual directories are also supported now):

<Sites>
  <Site name="MainSite">
    <VirtualApplication name="WebApp1" physicalDirectory="D:\Delo\Projects\WebApp1\" />
    <Bindings>
      <Binding name="HttpIn" endpointName="HttpIn" />
    </Bindings>
  </Site>
  <Site name="AnotherSiteOrSubDomain" physicalDirectory="D:\Delo\Projects\ AnotherSiteOrSubDomain ">
    <Bindings>
      <Binding hostHeader="anothersiteorsubdomain.myall.si" name="HttpIn" endpointName="HttpIn"/>
    </Bindings>
  </Site>
</Sites>

Things are much more similar to on-premises application then in HWC model. While RoleEntryPoint  runs under different process (WaIISHost.exe) than your web roles  (w3wp.exe), OnStart method still gets called but configuration settings work a bit differently. You cannot register or store some static values to be available to all websites. Remember its running in a different process... so you wont be able to access its data. What I mean by this is, probably everyone dealing with Azure Development has something similar to this in their role onstart method:

CloudStorageAccount.SetConfigurationSettingPublisher((configName, configSetter) =>{
    configSetter(RoleEnvironment.GetConfigurationSettingValue(configName));
});

While code is still perfectly sound, it wont do any good to our web roles, so the proper place to register it would by global.asax on ApplicationStart event. It all kind of makes sense, since different websites need different resources anyway.

Ninject.Extensions.Conventions provides convention based binding for Ninject modeled after the StructureMap 2.5 AssemblyScanner by Jeremy Miller.

When StructureMap users can use something like:

Scan(scanner =>
                {
                    scanner.AssembliesFromApplicationBaseDirectory(assembly => assembly.FullName.StartsWith("Ntk.Infrastructure."));
                    scanner.ConnectImplementationsToTypesClosing(typeof (IMessageHandler <,>));
                    scanner.ConnectImplementationsToTypesClosing(typeof (IMessageHandler <>));
                });

Ninject.Extensions.Conventions using GenericBindingGenerator can not:

            kernel.Scan(scanner =>
            {
                scanner.FromAssembliesMatching( "Ntk.Infrastructure.*.dll" );  
                scanner.BindWith(new GenericBindingGenerator(typeof(IMessageHandler<>)));
                scanner.BindWith(new GenericBindingGenerator(typeof(IMessageHandler<,>)));
                scanner.InTransientScope();
            });

So slightly modified version of GenericBindingGenerator called MultipleGenericBindingGenerator comes to the rescue:

            kernel.Scan(scanner =>
            {
                scanner.FromAssembliesMatching("Ntk.Infrastructure.*.dll");
                scanner.BindWith(new MultipleGenericBindingGenerator(typeof(IMessageHandler<>),typeof(IMessageHandler<,>)));
                scanner.InTransientScope();
            });

T4 templates for strongly typed ASP.MVC

MVC is a software pattern, that has been first introduced 1979 by Norwegian scientist Trygve Reenskaug.  The idea was to decouple the tight knot between views and models, to have a much more control over the software.

For example, very known ASP.NET 2.0 technology had the implementation of views, but controllers and models were combined in the code behind, which has the impact on the testing and other features, which is needed to build a easy proficient sustainable web solution.

Year ago Microsoft has launched a framework ASP.NET MVC for supporting software pattern and add additional value with different view engines , such as Razor, to eliminate this requirement. Since then, developers are having  few consideration about choosing between ASP.NET WebForms and ASP.NET MVC, but that is topic for another blog post.

MVC grew very quickly and alot of developers are using the new .NET framework to write efficient, light weight, powerfull web apps. Even though we do have a great enviroment for writing, testing, debugging  .NET apps, there is still a lack of string and mis-machted typos.

Consider following example:

<%:Html.ActionLink(»My link«,«Indeks«,«Home«) %>

This is a link to the Home controller, with a method Indeks. But wait, there is no indeks method there. It is a typo. Since we forgot to write x, instead of ks, we got a runtime error. We have to run the site, click of the link, read the error message, ask ourself, what did we do, use the debugger, run the site, check again, go through bunch of step, just because we made a typo.

This is the reason, why expert developers, such as david Ebbo, created a helper (T4 templates), that goes through the code and created a strongly typed strings for controllers, views, even a content.

Fixed upper example:

<%:Html.ActionLink(»My link«, MVC.Home.Index)%>

Its so easy. No more runtime checking, no repro bugs, even intellisense helps us understand, which name and even parameters we will use. 

You can use the following strongly typed helpers in the whole app, not only the views ( also in controllers, etc.)

It is quite simple to use it:

1.       Download the zip file on the codeplex site

2.       Required watching the David Ebbo intro with examples

3.       Unzip the file

4.       Add the 2 files in the root of your MVC app (T4MVC.tt and T4MVC.setting.t4)

5.       Build it

6.       Use it J

You can change the setting for t4 in the settings file to bend it to you will J

Happy no-typo coding.

I was asked for RadEditor MVC helper, so here it goes (copy paste code out) :

        public static MvcHtmlString RadEditorFor<TModel, TProperty>(this HtmlHelper<TModel> htmlHelper, Expression<Func<TModel, TProperty>> expression) where TModel : class

Some controls explicitly require to be placed within

If we want to use Telerik ASP.NET AJAX controls in MVC project, we must also use either ScriptManager or RadScriptManager. But since neither works very well here is more MVC friendly solution:

 public class RadMvcScriptManager : RadScriptManager
    {
        static string JavaScriptBlockFormat = @"<script type=""text/javascript"">
//<![CDATA[ 
    {0}
//]]>
</script>";

        protected override void Render(HtmlTextWriter writer)
        {
            foreach (RegisteredScript script in GetRegisteredClientScriptBlocks())
            {
                if (HttpContext.Current.Items[script.Key] == null)
                {
                    HttpContext.Current.Items[script.Key] = true;

                    if (script.ScriptType == RegisteredScriptType.ClientScriptInclude)
                    {
                        writer.WriteLine(String.Format(@"<script type=""text/javascript"" src=""{0}""></script>", 
                            HttpUtility.HtmlEncode(script.Url)));
                    }
                }
            }



            if (HttpContext.Current.Items["AppInitialize"] == null)
            {
                Page.Items["AppInitialize"] = true;
                writer.WriteLine(
                    String.Format(
                    JavaScriptBlockFormat,

                        $addHandler(window, ""load"", function(){Sys.Application.initialize();}); }
