In my last post I wrote a sample class that converts file extension to MIME type. Is it obvious that in many cases it is much better to have configurable list of mappings. For instance, you may have a configurable “white list” of file extensions that your web application allow to be uploaded and then [...]
The idea to write this post appears in my head just now when I’m starting to create a small application that uses Entity Framework and I need to do unit testing. The solution described here is useful for LINQ to SQL. I plan to try using the same solution also with Entity Framework. I hope [...]
Today I got this exception during my unit testing and I was a bit confused because of it and the situation that I got it. I have a class that is used by another class. I also have an interface for it but in this specific case I wanted to have a partial mock in [...]

In this post I’ll try to share with you how I’ve developed such a class for my SQLCEPad tool using TDD practices. [...]
