Create Custom Wizard C++ Project Template on VS 2010 and C# behind-code?

I wrote a Visual Studio Wizard Template using c# on visual studio 2012.

I followed the MSDN steps: I created a VS template, then I created a Class Library project with a class which implements the IWizard interface, I configured the .vstemplate file and etc...

I used the .Net functionality, as EnvDTE and VCProjectEngine.

But now I got into a problem: I used your solution on VS 2012 and everything worked well, but now I have to get it working also on VS 2010. I read in the MSDN that Project Template is not available in C++ 2010, and that I can use only the .vsz templates, which behave totally different, and the code behind is written in JavaScript. Do you know what I can do in order to have the closest solution on 2010? Is there anyway to write a template for C++ projects on 2010, which its behind-code, lineRunStarted() and RunFinished() is in c#? or even implementsIWizard?
