Can't run samples project with cocos2d-x 2.2.0 using wp8 platform

I try to run the HelloCpp in wp8 samples folder.
The visual studio 2012 open, but when I try to run the project, I got the following error

The debugger cannot continue running the process. The prject file '' has been renamed or is no longer in the solution.

How I can correct this issue?

I want to run the HelloCpp and TestCpp projects in wp8 platform.

I am facing the same problem for winRt and wp8 test cpp projects. Have you run them uptill now

I still can’t run the sample pojects.

I had the same problem when opening the project from the samples directory.
Just open the cocos2d-XXX.vc2012.sln from the root directory of cocos2d-x.
