Why does my splash screen not show in .NET MAUI Blazor app for Windows?

I have created a simple out-of-the-box .NET MAUI Blazor for net8.windows (only). I am using Visual Studio 2022 version 17.14.9 with maui workload 9.0.51. The splash screen image (splashscreen.svg) is located in the "Resources/Splash" folder. I have set the Build Action of the splash screen image to "MauiSplashScreen". When I run the application on Windows, the splash screen doesn't show. I have tried all of the below:

Clean and Rebuild: Delete the bin and obj folders in your project directory. Clean Solution: In Visual Studio, go to "Build" > "Clean Solution." Rebuild Solution: Then, "Build" > "Rebuild Solution." Restart Visual Studio: Close and reopen Visual Studio to ensure all cached data is cleared. Uninstall and Reinstall: I have tried uninstalling the app from your Windows machine and then redeploying it.

Here is a snippet of my .csproj file

<ItemGroup>
    <!-- App Icon -->
    <MauiIcon Include="Resources\AppIcon\appicon.svg" ForegroundFile="Resources\AppIcon\appiconfg.svg" Color="#512BD4" />

    <!-- Splash Screen -->
    <MauiSplashScreen Include="Resources\Splash\splashscreen.svg" />
        
    <!-- Images -->
    <MauiImage Include="Resources\Images\*" />
    <MauiImage Update="Resources\Images\dotnet_bot.svg" BaseSize="168,208" />
    <MauiImage Update="Resources\Images\splashscreen.svg" />

    <!-- Custom Fonts -->
    <MauiFont Include="Resources\Fonts\*" />

    <!-- Raw Assets (also remove the "Resources\Raw" prefix) -->
    <MauiAsset Include="Resources\Raw\**" LogicalName="%(RecursiveDir)%(Filename)%(Extension)" />
</ItemGroup>

Any help would be appreciated.

Solution

  • Windows (or macOS) apps do not have a built-in concept for splash screens. These are only displayed on iOS and Android.
