Using web services in C# and in general in .NET based applications is really easy. All you need is a service URL and Visual Studio will generate both proxy classes for service communication and configuration for web service endpoints and bindings...read more

Last year I wrote an article about ASP.NET web application security check list. Apparently there are always more things to add to improve your web application security...read more

Dealing with shared collection in application is always a bit tricky. You have to take care of concurrent access if you are accessing from multiple threads. One more thing which does not look so important as it is not difficult to implement is managing keys for addressing values...read more

In .NET working with configuration is really easy and there are bunch of .NET classes that rely on config values so you do not have to specify values in their constructors. For me it a common practice to instantiate database connections of WCF client by only creating an instance with parameterless constructor while keeping values in config file. In case you have to use these kind of classes in a long running process, like windows service on which other processes are depending on...read more

This article is base don the article I wrote in September last year. Basically I wrote this piece of code because I needed something really lite for one way binding. There are a bunch of light ORMs and ORM-Like solution, but both of them provide two way binding, but for me insert/delete/update commands were already handled by stored procedures as it was an existing solution which needed some new features, so I needed something to make reading a lot easier...read more

Most of developers, at least all the ones I know mostly use Console to test their code as it is the quickest way to do it. Despite unit tests, console is a fastest way to test your code where you can easily output the results. However if you have a lot of text in output you can get lost in results...read more

I've used GoogleMaps on several web projects and it seemed to me that I'm repeating a lot of code used in the previous projects which lead me to write a common Javascript library to help me easily reuse the code by only copying the JavaScript library to a project or referencing it from CDN. I could not think of a better way to build this library than to use jQuery and build a pligin for this. ...read more

Reading from application config is pretty easy in .NET. You literally need one line to fetch the value...read more

Sitemap.xml is important component of SEO which is responsible for indexing your website. Search engine robots are generating indexes of your website based on this file.

Searching files on the file system is pretty easy using System.IO namespace classes. The problem is if you need to youery file system with some things which are related to a file, but not related to file system itself. This is the case for searching images or any other media files...read more

By default object instances in .NET are never "trully" clonned. Instead .NET is doing shallow copy of instances which means if you have one variable which is object instance and you assign that variable to other variable, both of them will point the same instance of that object. Basically you created two pointers of the same object instance. ...read more

HTML is a markup language same as XML, but still there are differences which make dealing with them a bit different. Basically HTML is a strict structure in terms of node sets and attribute sets, but in general more documents online are not exactly following the proper structure since browsers usually manage to deal with rendering out the document in UI. However, this makes it more difficult to read them in case you want to from website itself as you cannot apply all XML rules since structure is not strictly followed. ...read more

Of course, the best way to make you web application work fluent is to write the code properly and design the architecture of application to meet requirements and certain load depending of the type of application. But even though architecture is good, you can always improve performance by reducing processing in application code itself. Caching is the best way to boost web application performance and reduce load of both application (IIS) and data servers (SQL Server) ...read more

Cross-origin resource sharing (CORS) means that page from other domain can make request to some resource which is on other domain. For example, if you try to invoke some WEB API method which is running on different domain you will get exception in the script. By default CORS are disabled in ASP.NET bot you can easily enable them just by modifying web.config for IIS7 and newer versions pf IIS. ...read more
