Problems with the System.Windows.Form package with C# (Visual Studio)

I am VERY new to C# and I'm trying to make a program that will simulate a mouse right-click when it detects sound. Here is my code...

The error I keep getting is below. I have been trying to figure out how to properly get System.Windows.Forms to work, but I do not have this solution explorer... and I'm new to visual studios so I don't know how to fix this or if I am even on the right track.

Unhandled exception. System.BadImageFormatException: Could not load file or assembly 'System.Windows.Forms, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'. Reference assemblies should not be loaded for execution. They can only be loaded in the Reflection-only loader context. (0x80131058) File name: 'System.Windows.Forms, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' ---> System.BadImageFormatException: Cannot load a reference assembly for execution.

Here is my code below. Everything works until I try to make my program right-click. What am I missing here? How do I fix the Systems.Windows.Forms error? I really do not know what I am doing lol but I feel like I'm so close if I can just fix this last problem.
