Mahapps.metro: Visual Studio Designer doesn't render correctly

[alan0428a]

Describe the bug

I am following the QuickStart to get familiar with MahApps. However, my Visual Studio Designer seems like it doesn't render the window correctly. It still renders the original WPF window. But when I run and debug the project, it runs perfectly without any issue.

I've uploaded the code to my github.

Steps to reproduce

1. Following the steps on QuickStart
2. See Visual Studio Designer

Expected behavior

Visual Studio Designer should render MahApps window properly

Actual behavior

Visual Studio Designer doesn't render properly

Environment

MahApps.Metro version: v2.4.3
Windows build number: Win10 Enterprise 10.0.19042 Build 19042
Visual Studio: 2019 16.8.3 Professional
Target Framework: net5.0-windows

Screenshots

Visual Studio Designer doesn't render properly

Run the project without any issue

@alan0428a This is a limitation of the Visual Studio Designer. It can not render the full window style (including caption).

Wow, thanks for the prompt reply!! (In 1 minute OMG)
Then what's the suggestion for the developers when using MetroWindow? Run the project directly and using Visual Studio Hot Reloading mechanism to modify XAML and check the result directly?

@alan0428a If this work, then yes. The inner Xaml content should be visible in the designer, it's only the caption and border which doesn't render.

Yes, the inner XAML content renders properly. Thanks for the clarification :)
