This creates a native wrapper around managed C# classes using C++/Cli.

Include a reference to CSharpToCpp.DLL and mark the classes you want exposed using the ExposeToCpp Attribute.

Then run CSharpToCppGenerator pointed at your Dll and it will parse it generating the files you need to complie 
into a c++/cli dll.

Works with String and native types (int, double, bool). Support for List and Dictonary soon.

For Example:

[ExposeToCpp]
public class TestClass
{
	public String ClassName { get; set; }
	public int ClassCount { get; set; }

	public TestClass()
	{
	}
}
