Question

Is there a sample MAUI application to call c++ libarary

Yang Yang 46

I have a cross-platform library written with C++, I use this library to create model and display it with OpenGL. Now I'd like to choose MAUI to create a desktop application and call above library to complete interactions. Now I need a sample for reference on how to collabrate with c++ library/codes in MAUI application.

Hi @Yang Yang ,

Can this library work properly? We need to make sure that the C++ library can be built, please let me know the result after testing.

sure, this c++ library could be built. Now I used MFC to call this C++ library, and I would like to use MAUI to write my application but not MFC

Hi @Yang Yang ,

We can use P/Invoke to consume a native library, you could try to check this doc - Use C/C++ libraries with Xamarin, then try to adjust to implement a version of MAUI. Please feel free to let me know if you have any other issues.

The referenced article is very good! I myself used it to successfully make the NuGet packages for 2 C++ libraries I needed for my Xamarin.Forms mobile application. The article was, however, written in 2019 for Xamarin (which is now depreciated) on Visual Studio for Mac (which will no longer be supported soon). Now I am converting my apps to MAUI and the NuGet packages I made for Xamarin.Forms do not work for MAUI. Is there something similar written for MAUI and Visual Studio 2022 for Windows? I haven't been able to find anything so far and don't know exactly how to "adjust to implement a version of MAUI".

Overall, this is NOT the correct answer to this question since the referenced procedure relies on tools (VS Code for Mac and VS for Mac) that are no longer available. I cannot believe that there isn't a better way to build C/C++ library code to create a cross platform NuGet package for MAUI. I am specifically building library code provided by government agencies (NOAA and USNO), so they are a little behind the times. Can somebody else help? How do I reject this answer?
