Maui Preprocessor in Blazor Hybrid

[AathifMahir]

I have a Blazor Hybrid App, and all the Presentation/Razor Components reside in a Class Library that can be shared between the Blazor Web Assembly app and Blazor Hybrid App. The current issue is that I need to implement specific logic that runs exclusively on the Blazor Hybrid App within that class library. How can I accomplish this? Is there a preprocessor for Maui or any other solution?

For example:

#if Maui

You can achieve that using Dependency Injection.

1. Define service interface in your shared lib and desired implementation in target project (MAUIHybrid/Web or both).
   You can still use common classes shared between projects.
2. Register e.g. builder.Services.AddTransient<IMyService,MAUIMyService>();

In my case, I don't have different implementation for web and hybrid project, most of the implementation were same except I want add some additionally code to razor components when running on hybrid, that's all

If you need just a flag which tells you that your code is executed in Hybrid you can create static variable in common lib
public static class Config { public static bool IsMaui {get;set;} }

Than you can set Config.IsMaui=true on your MAUI project during initialization
Your components can use this flag for specific logic/component rendering

That's a great idea, in that case I can extend the functionality with which platform that app is running on as well. Thanks
