I have class library that contains some XML-files as embedded resources. Reading these files at runtime is very easy. It takes only couple of lines of code.

Another new SEO feature that ASP.NET 4.0 introduces is support for meta description and keywords. I think these are the most abused SEO features ever and search engines are very careful when considering these meta tags but I am very sure that there are still engines that respect those tags and that’s what makes these new features very useful.

ASP.NET 4.0 introduces some SEO improvements. Response has now new method calledRedirectPermanent(). This method performs same redirect as Response.Redirect() but it uses response code 301. You can find more information about HTTP response codes from HTTP 1.1 specification, chapter 10. Status Code Definitions.

My previous posting was about performance of Fibonacci numbers algorithms. In this posting I will introduce you some problems related to limits of our usual integers and introduce you new feature in .Net Framework 4.0 – big integers. Big integers are useful when solving different mathematical problems. Also they are used in cryptography.

Performance of algorithms is important topic if you want to write programs that work fast and doesn’t eat too much resources. In this example I will show you two implementations of famous Fibonacci numbers algorithm and let you compare how these two implementations perform. This posting will be also introduction to my next posting to keep it smaller and to keep focus on point.

.Net Framework 4.0 has parallel computing extensions for LINQ. Previously it was possible to download parallel extensions for LINQ separately from CodePlex. Of course, you can still use these extensions if you have older version that 4.0. I wrote a little, simple and pretty pointless example that illustrates how parallel queries work in .Net Framework 4.0.

.Net Framework 4.0 introduced a new class called Lazy. Lazy provides support for several common patterns of lazy initialization, including the ability to initialize value types and to use null values. It’s a powerful and very useful beast but underrated in practice. Here’s how to use it.

One quick posting. I wrote yesterday extension method for SharePoint that checks if view exists. I think it is far better for performance if I don’t live on try…catch to find out if view exists or not. Extension method that you have to put in static class is here.

Web page that is not attacked by security team or developers and testers before going to live can be considered as unsecure because nobody knows how it behaves under attacks. Unfortunately there are many web pages that are not secure and not event tested with security in mind. If some of these web pages happen to be a e-commerce sites then it is not hard to guess what kind of data attacker may find in this system about us. How can we be sure that our systems are protected against attacks? (more…)

I needed a little bit customized forms that look similar to standard ones for one SharePoint solution. I have list with many fields and it is very inconvenient for users to fill these fields if they are following one after another. As there is no simple solution for this I created my own custom solution.
