1. Effect Showcase

Enjoy the effect:

2. Preparation

Create a WPF project, for example, the site owner created a WPF project named Login5 using .NET 7.

Find an image as decoration, placed on the left side of the login form:

Add NuGet package MaterialDesignThemes:

<PackageReference Include="MaterialDesignThemes" Version="4.6.0-ci176" />

3. Brief Explanation + Source Code

The interface is relatively simple, with not much code, so we’ll just paste the code directly.

MainWindow.xaml

The overall layout and style of the interface are all in this file:
