Simple Dll and WPF Form

Job ID: 35142616

Budget: $2 – $8 USD

I need a project that creates a dynamic dll in c++, and a project of a FORM c# (preferred in WPF) that sends and receives information from this dll.
The form has only 1 button that sends a string to the dll. When received by the dll, it returns any other string for a label on the form.
I need the project of both applications to open in Visual Strudio.
