FP SDK: Errors when opening Sample App

Dear community,

I have one problem, which I hope you could help me assist with:

I have Visual Studio 2008 SP1, installed Legacy Flexpendat SDKs and I have downloaded 'Custom Views' sample application, so I could see how the apps are done.
But unfortunately, when I open the project I get errors at each class, see screenshot bellow:


Please help. :)
