Which version of MVC am I using?


Open web.config file and find the System.Web.Mvc assembly definition:

assembly="System.Web.Mvc, Version=3.0.0.0 ..."

It's an MVC3 as you see. Via web you can use MvcDiagnostics which is similar to phpinfo() functionality in PHP.

The Web API Checklist — 43 Things To Think About When Designing, Testing, and Releasing your API


When you're designing, testing, or releasing a new Web API, you're building a new system on top of an existing complex and sophisticated system. At a minimum, you're building upon HTTP, which is built upon TCP/IP, which is built upon a series of tubes. You're also building upon a web server, an application framework, and maybe an API framework. Most people, myself included, are not aware of all the intricacies and nuances of every component they're building upon. Even if you deeply understand each component, it's probably going to be too much information to hold in your head at one time.

A Complete Guide to the MVC 6 Tag Helpers


Tag Helpers are a new feature in MVC that you can use for generating HTML. The syntax looks like HTML (elements and attributes) but is processed by Razor on the server. Tag Helpers are in many ways an alternative syntax to Html Helper methods but they also provide some functionality that was either difficult or impossible to do with helper methods. Each tag helper has a different behavior and different options. This post will give you an overview and links to more details for each tag helper.

ASP.NET 5 Project Basics


When you create a new ASP.NET web application using the Web Application template, you are presented with a raft of new folders and files in a completely new structure. This article is the first in a series that attempts to demystify the new structure and the role that some of these files play. The article series starts with the Empty template and adds the various files that you might see in the web application template progressively to illustrate their purpose. This article uses Visual Studio 2105 RTM and ASP.NET 5 Beta 6. It will be updated in line with future releases.

ASP.NET MVC ActionFilter: Custom Authorization


A while back, I posted my top 5 favorite ASP.NET MVC Action Filters and enhancing your controllers with ActionFilters, but honestly, it doesn't matter which ActionFilter I pick. I just love the idea of ActionFilters. They are just so simple and powerful...and pretty darn cool! For example, if you want to protect a certain section of your website, you place an [Authorize] attribute on an ActionResult method in your controller. If someone comes to your website and they try to hit that page and they aren't authorized, they are sent to the login page (Of course, you need to modify your web.config to point to the login page for this to work properly).

IMPROVE SERVER PERFORMANCE WITH ASYNCHRONOUS WEBAPI


In this article I want to show, how you can improve server performance dramatically by using Microsoft asynchronous WebAPI. The text shows, how a Microsoft WebAPI service backend can be improved to handle request asynchronously and so to increase the number of concurrent clients the server can handle. You can boost the user experience of client applications with asynchronous WebAPI services by being more reactive and fluent in the user interface. This document will not describe the client side in deep, focus is on the performance of the server side. In the following section, I write a very simple web service using Microsoft WebAPI, measure the performance of concurrent requests to that service and compare the results to a second scenario, where we will make the service asynchronous.

INSIDE SIGNALR – ADDRESSING CLIENTS, RETURN VALUES, BROKEN CONNECTIONS AND SECURITY


During my last lecture about ASP.NET SignalR in the .Net Developer Group Berlin-Brandenburg, some questions came up from the audience. I like to try to answer these questions with this blog post. The questions were about how address specific clients from the server side, how to return values after calling a function at a specific client and how broken connections are handled. And also the evergreen-question came up: How to secure SignalR applications. This post is about SignalR 2 and will not cover previous versions. You can find very good tutorials here: ASP.NET SignalR 2. Let's have a look at the questions step by step.

DEPENDENCY INJECTION IN ASP.NET VNEXT


Microsoft changed the way how dependency injection (DI) is done in ASP.NET vNext. In previous versions of ASP.NET there were different entry points for user defined classes like the IControllerFactory for ASP.NET MVC applications or the IHttpControllerActivator for ASP.NET WebAPI applications. Starting with ASP.NET vNext DI becomes a first-class citizen in the framework through the whole stack. With showing the new DI features in ASP.NET vNext, discussions came up whether it is the correct way to do DI. In this post I like to show how DI works in ASP.NET vNext and then lead to the current discussion about it. At the end I like to ask you for your opinion.

ASP.NET WebAPI: Getting Started with MVC4 and WebAPI


I've spent the last year working on ASP.NET MVC3 and feeling good this year on MVC4. I got some new exciting features after updating to MVC4, Web API is one of those exciting features. I have read a lot on this feature and have read a lot of good articles on the web. But I didn't get any article that covers all the concepts in one place. So I tried to combine those in one place for beginners. Please don't consider this article as my own invention.. everything is taken from several articles. Please navigate the links in the History section for further details.

Profile and debug your ASP.NET MVC app with Glimpse


Glimpse is a thriving and growing family of open source NuGet packages that provides detailed performance, debugging and diagnostic information for ASP.NET apps. It's trivial to install, lightweight, ultra-fast, and displays key performance metrics at the bottom of every page. It allows you to drill down into your app when you need to find out what's going on at the server. Glimpse provides so much valuable information we recommend you use it throughout your development cycle, including your Azure test environment. While Fiddler and the F-12 development tools provide a client side view, Glimpse provides a detailed view from the server. This tutorial will focus on using the Glimpse ASP.NET MVC and EF packages, but many other packages are available. Where possible I will link to the appropriate Glimpse docs which I help maintain. Glimpse is an open source project, you too can contribute to the source code and the docs.

Upgrading a Real-World MVC 5 Application to MVC 6


These are exciting times for web development on the Microsoft stack, but perhaps a little confusing as well. For many years the cycle of moving from one solution and project system to the next hasn't been overly complex. Sure, there have been breaking changes, I've felt those pains myself, but provided the framework you were using continued to live on, there was a reasonable migration path. Moving to MVC 6 is going to be a big shift for a lot of development teams, but that doesn't mean it needs to be scary, complicated or introduce instability into your project. It does, however, mean that you're going to need an attitude of learning, that you'll pick up some new tooling, you'll have to brush up on your JavaScript and work with some new concepts.

ViewComponents in ASP.NET 5 and ASP.NET MVC 6


Let's have a quick look at another new feature in ASP.NET MVC 6, and that is the ViewComponent feature. View components are intended to be replacements to ChildActions and, to some extent, of partial views. Traditionally in ASP.NET MVC (and in general in the textbook MVC pattern), you had to compose the entire model in the controller and pass it along to the view, which simply rendered the entire page based on the data from the model. The consequence of this is that the view does not need to explicitly ask for any data – as its sole purpose is to just act upon the model it received. While this sounds very nice in theory, it has traditionally posed a number of practical difficulties. There are a number of reusable components on pretty much every website – think a menu, a shopping cart, lists of all kinds, breadcrumbs, metadata and so on – so things that appear on multiple pages.

Infinite Scrolling Using JQuery Ajax And ASP.NET MVC


Web applications such as Facebook and Twitter use a technique known as infinite scrolling or endless scrolling wherein data is loaded on the fly when a user scrolls to the bottom of a web page. There are many jQuery plugins that help you enable such a feature in your web application. However, if you wish to avoid any third-party dependency or have some specific needs, you can add your own infinite scrolling with a few lines of jQuery code and ASP.NET MVC. This article tells you how that can be accomplished.

Improving Web API performance


ASP.Net Web API is a lightweight framework used for building stateless HTTP services. You can use Web API to design and implement RESTful services that run on HTTP. REST is an architectural style -- a set of constraints used to implement stateless services. Web API has already become the technology of choice for building light weight HTTP services. You can learn more on Web API from the asp.net site.

Web API, Async and Performance in an ASP.NET MVC application


With the multifold increase in processor performance as well as number of processor cores in a system, software systems are expected to scale horizontally with system hardware. However, software systems have the tough job of working with disparate systems that work at their own speeds (e.g. Network latency, Disk latencies, peripheral device latency and so on). So if we are building a system that does things synchronously, our throughput is always going to be limited by the slowest system in the chain. Thus, the ability of our software to initiate a task and do something else till that task completes, goes a long way to ensure we don't 'bottleneck' or 'wait doing nothing' on a slowly running component. Rowan Miller had an excellent analogy of Async tasks to waiters at a restaurant, in his TechEd NA (2013) talk. To paraphrase – A system working asynchronously is like a waiter at a restaurant. More often than not, a waiter serving a table will be at Table 1, take an order, explain a menu item, deliver an order and then move away, free to do the same at Table 2. When Table 1 is done (deciding the order, requiring a refill, requesting the check) they will draw the waiter's attention and the waiter would come back to Table 1 as soon as they become available (or immediately if they are available). This mechanism of one waiter serving multiple tables ensures that you don't need as many waiters as the number of tables, to maintain optimal performance (in case of restaurant – experience). If we consider a computation unit (CPU + Coprocessors + Cache + System Bus etc.) to be a waiter serving customers, then async operations is the way to make sure that they don't waste time waiting while the customer decides what to order.

Opt in and opt out from ASP.NET Web API Help Page


The autogenerated ASP.NET Web API help page is an extremely useful tool for documenting your Web API. It can not only present information about the routes, but also show sample requests and responses in all of supported media type formats, and even display information for DataAnnotations. However, more often than not, you don't want all endpoints to be visible in the help page. Let's have a look at how you can opt in and opt out from the ASP.NET Web API Help Page with your resources.
