There is, you can still do it..

I have VS2015 and here is what I did:
1. Create a new project
2. Go to the bottom 'Online'
3. Search for 'C++ Windows Forms'
4. This should install the template
5. Create a new project (Win32 Project), set everything up as DLL/empty project
6. In properties, add CLR support (/CLR)
7. Add your form (you should have a template 'C++ windows forms')
8. Have your DllMain code set up, start a new thread from it which will do the following:

winform2::MyForm^ myform = gcnew winform2::MyForm();

That's what I did and after injecting the form does show up.
