Introduction to Bower, Grunt, and Gulp in Visual Studio

Developers are now spending much more time writing and debugging JavaScript, CSS, HTML templates etc. Microsoft have responded by adding better tools for front-end development into their development environment, Visual Studio. In this article Jon Smith uses a sample application to demonstrate how he converted an existing ASP.NET MVC5 application to use these new tools… Read more

Keeping POST and GET Separated

The occasional problems that you can get with POST and GET are typical of the difficulties of separating any command and query operations. This separation is tricky to achieve, at least in ASP.NET MVC. Dino suggests some ways of avoiding errors and minimising the confusing warning messages.… Read more

How to Take an Asp.Net MVC Web Site Down for Maintenance

Keeping a customer facing web site up and performing well is a challenge, especially when you are still adding new features. While providing an "always on" experience for users is preferred there are times when it is easier to take the site "down for maintenance" and fix those things that are just too difficult and costly to do with the site up. Jon Smith describes his solution to a controlled "down for maintenance" approach for ASP.NET MVC sites.… Read more

Tips and Tricks about Razor Partial Views

Partial views in ASP.NET MVC allow you to reuse and customise components to act like user controls. They consist of both code and markup. They are an idea that is easy to grasp but they have great potential for the more adventurous developer who is prepared to experiment. Dino Esposito explains.… Read more

So You Need to Expose JSON Endpoints

Even the most experienced programmers can be caught unawares by software they've used for years without trouble. Dino Esposito explains why and how the JSON method in an ASP.NET MVC controller class suddenly started to cause an exception on a production server, and how he fixed the problem.… Read more

SQLXML Bulk Loader: The Sequel

SQLXML isn't exactly new technology, and parts of it aren't pretty, but if you need to heave vast quantities of XML data into a SQL Server database then you may come to appreciate the raw speed of which it's capable. Adam Aspin shows how to configure the SQL XML Bulk Loader tool for optimal data loading performance.… Read more

Monitor Server Tasks with ASP.NET SignalR and Bootstrap

Despite the fact that browsers were designed specifically to get information from the server only by requesting or 'pulling' it, developers have always yearned to be able to push data to browsers from the server. Typically, it would be to display, within a web page within the browser, the progress of a long-running task. Now ASP.NET SignalR and Bootstrap make it possible, with care. Dino explains how.… Read more

Selective Updates with ASP.NET SignalR

SignalR is great for all those tasks that one would otherwise need to rely on AJAX. However, it is much more versatile than this: it allows, for example, a server process to update users' browser windows selectively rather than broadcast to all, and can treat groups of users in different ways. Dino explains how this magic works.… Read more

SQLXML Bulk Loader Basics

SQLXML isn't exactly new technology, but like the even more venerable BCP, it remains the quickest and most reliable way of heaving large quantities of data into SQL Server databases. SQLXML is very versatile, and once set up is wonderfully reliable ETL system, but isn't trivial to learn. Adam Aspin comes to the rescue with a simple guide.… Read more

ASP.NET SignalR: Old-fashioned Polling, Just Done Better

A website often needs to update a page as the underlying data changes. You can, of course, just poll the server every few seconds on the browser via JavaScript, but to receive live updates from a site it is better to push data to the browser, using server-based SignalR. This uses web sockets to do this rather than browser-based polling where web sockets are supported on the browser. Dino explains how.… Read more

Introducing Single Sign-on to an existing ASP.NET MVC application

Implementing a single sign-on for a set of a company's business applications isn't hard if they are all new applications, especially if you use WS-Federation and and Identity server such as Thinktecture. If it is a mix of new and existing applications then it helps to sort out any problems if you first understand the technology as a whole, and appreciate how it works. Jarek shares his experiences.… Read more

The Compromise Between Development Time and Performance in Data-Driven ASP.NET MVC

As developers we always want to produce efficient code, but efficient in what - development time or overall performance? In this article Jon Smith describes how to investigate and understand performance so that you can decide how to balance these two goals. The article starts with high level performance issues and drills down to detailed code tuning using examples taken from real applications.… Read more
