The evolution of asynchronous controllers in ASP.NET MVC
Jan 1209Asynchronous operations in ASP.NET MVC have always been left a bit behind. They appeared in ASP.NET MVC 2, remained untouched in v3, but now in MVC 4 (especially in combination with C# 5 and async/await) they reached the same easiness of use of the standard synchronous controller. Now (or better, in a few months with the release of ASP.NET MVC 4, .NET 4.5 and C# 5) you can write public async Task<ViewResult> Stuff() { return View(await DoStuff("Some stuff")); } In this post I’m going to...

Using SignalR to broadcast a slide deck
Dec 1106Last week, Ive discussed Techniques for real-time client-server communication on the web (SignalR to the rescue). Weve seen that when building web applications, you often face the fact that HTTP, the foundation of the web, is a request/response protocol. A client issues a request, a server handles this request and sends back a response. All the time, with no relation between the first request and subsequent requests. Also, since its request-based, there is no way to send messages from the serv...

Techniques for real-time client-server communication on the web (SignalR to the rescue)
Nov 1129When building web applications, you often face the fact that HTTP, the foundation of the web, is a request/response protocol. A client issues a request, a server handles this request and sends back a response. All the time, with no relation between the first request and subsequent requests. Also, since its request-based, there is no way to send messages from the server to the client without having the client create a request first. Today users expect that in their projects, sorry, experience...

Rewriting WCF OData Services base URL with load balancing & reverse proxy
Nov 1108When scaling out an application to multiple servers, often a form of load balancing or reverse proxying is used to provide external users access to a web server. For example, one can be in the situation where two servers are hosting a WCF OData Service and are exposed to the Internet through either a load balancer or a reverse proxy. Below is a figure of such setup using a reverse proxy. As you can see, the external server listens on the URL www.example.com, while both internal servers are ...

Why MyGet uses Windows Azure
Sep 1106Recently one of the Tweeps following me started fooling around and hit one of my sweet spots: Windows Azure. Basically, he mocked me for using Windows Azure for MyGet, a website with enough users but not enough to justify the scalability aspect he thought Windows Azure was offering. Since Windows Azure is much, much more than scalability alone, I decided to do a quick writeup about the various reasons on why we use Windows Azure for MyGet. And those are not scalability. First of all, heres a...

Windows Azure Accelerator for Web Roles
Jul 1113One of the questions I often get around Windows Azure is: “Is Windows Azure interesting for me?”. It’s a tough one, because most of the time when someone asks that question they currently already have a server somewhere that hosts 100 websites. In the full-fledged Windows Azure model, that would mean 100 x 2 (we want the SLA) = 200 Windows Azure instances. And a stroke at the end of the month when the bill arrives. Microsoft’s DPE team have released something very interesting for those situati...

A first look at Windows Azure AppFabric Applications
Jul 1107After the Windows Azure AppFabric team announced the availability of Windows Azure AppFabric Applications (preview), I signed up for early access immediately and got in. After installing the tools and creating a namespace through the portal, I decided to give it a try to see what it’s all about. Note that Neil Mackenzie also has an extensive post on “WAAFapps” which I recommend you to read as well. So what is this Windows Azure AppFabric Applications thing? Before answering that question, le...

Enabling conditional Basic HTTP authentication on a WCF OData service
Jun 1128Yes, a long title, but also something I was not able to find too easily using Google. Here’s the situation: for MyGet, we are implementing basic authentication to the OData feed serving available NuGet packages. If you recall my post Using dynamic WCF service routes, you may have deducted that MyGet uses that technique to have one WCF OData service serving the feeds of all our users. It’s just convenient! Unless you want basic HTTP authentication for some feeds and not for others… After doin...

MyGet now supports pushing from the command line
Jun 1101One of the work items we had opened for MyGet was the ability to push packages to a private feed from the command line. Only a few hours after our initial launch, David Fowler provided us with example code on how to implement NuGet command line pushes on the server side. An evening of coding later, I quickly hacked this into MyGet, which means that we now support pushing packages from the command line! For those that did not catch up with my blog post overload of the past week: MyGet offers ...
