Calling c++ library from .NET MAUI blazor or MAUI xaml

Question

Hi,

We are building cross platform application and searching whether we can call C++ library from .NET MAUI Blazor or .NET MAUI xaml.

Could anyone advise the feasibility and if feasible any end to end example to refer.

We are looking for cross platform functionality on iOS, Android and Windows.

Maui apps can call c/c++ via the p/invoke library:

the main task is to define the entry points and mapping (marshalling) of the parameters. you usually use .h file to determine how to do this. Calling native libraries is common enough with Maui, there is support for binding libraries (generated wrappers):
