Sometimes, especially with C# you hear alot of “common knowledge” about performance and developers mistakes. As an (bad) example I want to refer to 8 Most common mistakes C# developers make and in particular point 7 “using foreach instead of for”. So whats wrong with this kind of post? First of all, it refers to […]

Today we introduce a new category on AllInSight.de: Difference between a duck. We took that line from the movie Postal. And the category is about things that are the same or look alike and also about things other think are the same but actually they are different. For a start I’ll show that for and […]

As I mentioned in the last post, you can’t use SlidingExpiration and AbsoluteExpiration a the same time. Thats by design. Thanks again, Microsoft. But there is a workaround. First i will present the solution and then a short and easy way to use it. The ObjectCache / MemoryCache has a nice little function called CreateCacheEntryChangeMonitor. […]

Today i want to show you how to use enumerations to set multiple values in a variable using bit-flags. Normaly enums are an easy way to set a single value and check later which value is set working with a static name throughout your entire application. Enums are much better then magic numbers or constants […]

Sometimes its necessary to change the mousecursor of an application to show the user that something goes on. Most times we just want to show the wainting-cursor as long as an operation takes and switch then back. The first problem you’ll encouter, is exception-handling.

It is very helpful to know if and what exceptions a method can throw. Unfortunately there is no throws-keyword like in Java.
