Discussion – Lesson 8 - Birthday reminder in C# .NET WPF - Wiring layers

I like these WPF tutorials a lot. Let's face it. Coding for the console is nice and makes us feel all super geeky and hacker-like but apart from us coders there is nobody who want's to use that. So one has to learn to use Forms!

I have a question regarding Visual Studio and Forms. I found my Solution manager quiet messy and decided to put the forms into a folder. Interestingly this breaks the application completely. VS is not even able the debugger anymore, the app crashed before reaching the Main()-Method.

How can I fix this? There surely has to be a way to move and reorganize your application files after you created them!

Hello Lennart,
generally it's not a good idea to move autogenerated content, I'd create a new one. The best way to divide your WPF app into folders is to create the folders and create new Windows in them (right click on the folder and choose "Add -> Window..."). Once you've your Windows in the folders ready, modify the App.xaml file to set the default Window in the StartupUri attribute:

<Application x:Class="WpfApp1.App"
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
             xmlns:local="clr-namespace:WpfApp1"
             StartupUri="YourFolder/Window1.xaml">
    <Application.Resources>

    </Application.Resources>
</Application>

Feel free to remove the original MainWindow.xaml file later.
