I have a .NET MAUI app that needs to use custom native Android and iOS libraries. I was able to successfully create Android binding library with generated .cs files in BindingLib/obj/debug/net6.0-android/generated/src. However, I can only access interfaces of the classes. None of the methods can be accessed. I took a look at the generated .cs files. They all have this: DoNotGenerateAcw=true. I assume that since Android Callable Wrapper is not generated, none of the methods can be called? If so, how can I set DoNotGenerateAcw to false? Is there some parameter that I can set in csproj to achieve this?

Regarding the binding library, do you refer to the steps of Xamarin.Forms?
If so, please refer to this official session Binding Native Libraries for .NET MAUI to get the correct steps on how to bind library on MAUI.
If not, for further investigation, could you please provide more detailed information about your development environment, such as VS and MAUI version, and the steps of reproducing this issue?
No, I didn't refer Xamarin.Forms docs. Thanks for the link. It was the one I used as a guide for including my native Android and iOS libraries. It helped. But there are issues that still exist

i've segnalated the same problem in june.
the feedback bot response had me speechless.
I figured it out. I think this probably has nothing to do with DoNotGenerateAcw being set to true. The reason is probably I didn't call the class' method inside a method. When I tried to call it in a method, it worked. I do feel that the current Visual Studio (Visual Studio 2022 for Mac Preview 17.4) version is buggy (Here is a bug report on visual studio developer community that is related to this bug). When I tried the same steps on a newly created project, I couldn't get "using namespace" working with the binding library ( I think it is the same issue that you reported. It didn't know the generated cs files). I had to open and close Visual Studio multiple times and do other things, and then it worked.
But I do have an issue with including an iOS binding library. When building the library, it falsely added dots before some class names in the generated cs files. Also, sometimes it reported errors that were totally unrelated. For example, it would give me many errors in the MAUI project, not the binding library project.
please comment on visual studio developer community link.
maybe with some interactions vs devs become aware of the problem.
