| This seems like a hot topic and so I decided to make my own class to do this simple function. Its got a few extras that may not be needed for your implementation but feel free to rip those out or add more functionality to it :)
Added this as a project.

| | I created a WinForms utility that depended on some DLLs and wanted the user to be able to just download and click on the exe to run the app. Usually if your exe needs some other files you wrap things up into a package and the user has to go through an install process. This takes time and forces the user to unistall if they don't want the program after it's served its purpose. I didn't like this and found a way to embed the files I needed into my exe and extract and link them when the program ran. |

| At some point, every organisation moving to .NET is going to have to choose which .NET languages to adopt. Microsoft is offering four languages out of the box: C#, VB.NET, Managed C++ and JScript. This article briefly discusses our opinions on these language offerings and who's going to be using what.
In short, we believe C# will gain predominant market share; JScript is a non-event; C++ will continue to be marginalised and VB.NET doesn't appear to have a ready market.
