We want to build a web application using ASP.NET MVC and mobile app using Xamarin. But I am not sure how we can share the business logic between the 2 projects (Web Application and the Mobile app)?
I usually build web applications using ASP.NET core MVC, but never share the business logic of this web application with a mobile application.. so can anyone advice on the appraoch i need/can follow to share the logic between the web application and the mobile application?
Thanks

Could you describe more about "Share the buisness logic", you want to add some of the same code for your ASP.NET MVC project and Xamarin.Forms project, right? Or do you want to call Web Api in your Xamarin project?
For the former, you could try to create a class library, then reference the library into your Xamarin project and web project. For more details, please refer to Create a .NET class library using Visual Studio - .NET | Microsoft Learn
For the latter, you can refer to Consume an ASP.NET Web Service (ASMX) - Xamarin | Microsoft Learn
Wenyan Zhang (Shanghai Wicresoft Co,.Ltd.) i mean to share the business logic inside the Controllers between the web project and the mobile app project..
Thanks

To share code between Xamarin and another project you move the shared code to its own library. This library must a .net standard 2.0 library. Then reference this library from both projects.
You may need to think about abstracting data access in the library as the apps may have different access to data.
i mean to share the business logic inside the Controllers between the web project and the mobile app project..
Web API is the modern ASP.NET solution for sharing data across different clients.
If the MVC controllers already exist and contain business logic then you'll want to move the business logic to an application layer (DLL) that your project can share can share.
