Load a C# WPF form inside a library from a CLI C++ application

I have a dll file written in C# that is in the same solution as my application which is written in C++ with some files set to compile under the /cli flag. I'd like to load the WPF form inside my C# dll and display it in the C++ /cli application.

I already have my C++ application configured to display WPF content, as I am currently programatically adding controls onto the WPF form but I have not been able to find out how to load a form from an external resource at runtime.

You can load an external DLL into your project like this

Dim assembly As Assembly = Assembly.LoadFile(libraryPath & "filename.dll")
Dim type As Type = assembly.[GetType]("NameSpace.ClassName")

// i'm loading as a form here but can be any control
Dim frm As Form = TryCast(Activator.CreateInstance(type), Form)

one final note, if you're loading a class or control inside the loaded form (above) that resides also inside the same assembly you also need to load it first before calling it in the form

If you added the control reference to your CLI project, you should be able to have access to your control; having application handle use ApplicationHandle->Run(YourWindow) method.
