Read moreCodeWatch sample fields with underscore convention check
This time I'll talk little bit about code best practices. Usually one thing what every development team does at the beginning of the project is to agree on some conventions.

Read moreDebugging WPF Bindings
WPF + MVVM is a very common way to make windows apps. It introduces the concept of data binding. We create a view-model based on one or many models and bind it to the view. Usually, it is easy... But how do you debug bindings if something is not going right? For example, you have Control Templates and styles and so on introduced in your app.
Read moreLogging in application
Logging information on how our application behaves is very often omitted or not properly handled by developers. We don't know what and when to log. We don't have a logging strategy.

Using different .config file in .NET application
In .NET world executable files using by default configuration file with special name. Microsoft has implemented following pattern: executable: program.exe and corresponding configuration file program.exe.config. In many scenarios this pattern is fitting well, but there are some cases when something else necessary. In my situation common configuration file was desirable!
