To call a C++ WinRT component in .NET 6, you will need to use the Windows Runtime C++ Template Library (WRL) to create a C++/WinRT projection of the component. This projection can then be consumed in C# or other .NET languages using the Windows.Foundation.WinRT namespace.
Here is an example of how you can consume a C++ WinRT component in C# using WRL:
- In your C++ component, define the component's interface using the
- In your C# project, add a reference to the C++ component's projection. This can be done by adding a reference to the component's .winmd file, or by adding a reference to the component's project if it is part of the same solution.
- In your C# code, create an instance of the component's class using the
newkeyword and the component's class name.
- Call the component's methods and properties as you would with any other C# object.
It's important to note that C++/WinRT is a standard C++ library, you need to make sure that your C++ code is compatible with C++/WinRT before you can call it from C#.
