Getting Started with .NET MAUI for Desktop Applications

Posted by JaneDoe on

Hi everyone, I'm new to .NET MAUI and I'm trying to build a cross‑platform desktop app using C#. I've followed the official docs, but I'm hitting a snag with window handling on Windows. Any tips?

What I've tried:

  • Created a new MAUI project with dotnet new maui
  • Added a simple Button that opens a new window
  • Implemented IWindow for custom sizing

When I run the app, the new window appears but it's invisible on Windows 10. It works fine on macOS.

Any ideas on what I'm missing?

Make sure you set Window.Width and Window.Height after the window is created. Also, add DispatcherQueue.TryEnqueue around the sizing code.

Thanks, Mike! That solved it. I also had to enable UseMauiWinUI in the csproj.
